Guidelines for Lab-TAs 1. Each lab TA is assigned two days in a week. The lab sessions will be held @ CS Dept- DCF from 7.30pm to 10pm on all weekdays. TAs MUST report by 7.15pm to the respective Lead TA and mark their attendance. Repeated late comings will be reported to the Coordinator and HoD. 2. The smooth conduct of the lab sessions depends entirely upon the TAs' commitment and support. Please cooperate with the Coordinator and the Lead TAs. Prepare well for the lab sessions as per the assignment schedule given in the lab manual. Every day have a 5 min viva voce session with each student. 3. TAs should collect the mail ids and phone numbers of their respective students on the first day itself. This is required to communicate with the students regarding any sudden change in lab schedule. Similarly TAs have to share their contacts with their respective students. 4. Grading of assignments will be done ONLY in the lab, and during the allocated sessions. Students assigned to you should come only on the assigned day, and they can work till 11pm in lab for practice (if necessary). 5. All assignments submitted on the due date (i.e., the date of the assignment) will be given full credit of 15 marks. Then, for each delay of 1-week, 2 marks will be reduced. Assignments will not be given credit after the buffer week. 6. A student who finishes the assignment after the buffer week can email to the Coordinator and the Lead TA for that day. It will be considered only if it will make a significant difference to the grade. Regular TAs should not encourage or accept late submissions by email. 7. TAs who grade lab assignments will enter the marks in the mark-sheets given to him/her by the Lead TA. Later, the Marks-TAs will enter the marks on Moodle. Changes in marks, if any, must be reported to the Lead TA, who will work with the Coordinator and the Marks-TAs to update the same. 8. If a TA is unable to come to the lab on his/her assigned day, it is the TA's responsibility to find another CS1100 TA who has lab duty on ANOTHER day and inform the Coordinator (via mail and cc to Lead TA), at least 48 hours in advance, unless there are extenuating circumstances such as sickness, sudden travel, etc. Leave without duty arrangement will not be granted under any circumstances. The TA who is taking leave should ensure that the replacement TA is reporting in time. 9. All TAs have to do hall invigilation and paper correction of CS1100 quizes and end semester exams. TAs can avail the summer vacation only after getting approval from the Coordinator. (End Sem paper correction is on May 11, Sat) 10. On the first lab day of a month, TAs are requested to submit the filled up TA work load form to the concerned Lead TAs. After getting the signature from both the Lead TAs, submit the form to John Jose (Logistics Lead TA), in PACE Lab. Once the forms are signed by the coordinator an email will be send to all TAs mentioning that they can sign the acquitance bill in CS Office. 11. TAs should not spend the time for CS 1100 lab session for their personal assignments / projects etc. 12. Usage of cell phone and laptops inside the DCF labs are prohibited while the lab sessions are in progress.

General Instructions to students 1. Time: 7.30 PM - 9.30PM on all week days. 2. Venue: CSE Dept-DCF Software Lab and Systems Lab 3. Account Access: The students should carry their Institute ID on all lab days.

Each student should login using the User ID assigned to him/her. Backup of files stored in the accounts are not assured. 4. Teaching Assistants: One TA has been identified for every 6 students in a particular session. Each TA will be associated with the same set of students throughout the semester. The TAs will help the students in doing the assignments and evaluate the assignments. 5. Lead TAs (Day coordinators): A Lead TA is also assigned per lab day to coordinate the smooth conduct of the lab. The Lead TA will record the attendance and day wise marks of the students. Students can approach the respective Lead TAs for any help and clarifications. 6. Systems: On on Day-1, the TAs will allot permanent seating positions and systems to students which they have to follow through out the semester. 7. Evaluation: Total weightage for the assignments is 25%. Each assignment is worth 15 marks. The student should enter the code for all the programs of an assignment in the lab during the session. (a) The assignments shall be evaluated only in order. If a student does not complete an assignment in a particular session, he/she may complete the same during the week and get it evaluated during the following week. (b) Assignments are due on the same date itself as specified in the corresponding descriptions. The student can submit the assignment, without penalty, on the same day before 9:30pm. After that, for every week of delayed submission, 2-mark (out of 15) penalty will apply. (c) Labs 1-3 submitted after the end of the first buffer week will not be evaluated. However, the marks obtained will be considered only if it makes a significant difference in passing the course. Labs 4-8 will not be evaluated after the second buffer week. 8. All disputes regarding the marks obtained by a student should be settled between the TA and the student on the same day of evaluation. No further revision of marks is possible. 9. Change of slots for students: Change of assigned slot by students is not allowed. Students having any difficulty in attending the practice session in the assigned slot should contact the Coordinator. 10. Holidays: In case a weekday is declared as an Institute Holiday, the lab session for that batch will be conducted on the same day or on Saturday during the same week. The Lead TA (day coordinator) will decide the time, and inform the TAs and students. 11. Timetable Changes: If the Institute declares a different day’s time table for a given day, (On March 26 Tuesday, Friday TT to be followed), that WILL NOT apply to the Programming Assignment schedule. On March 26 students assigned to Tuesday only will attend the lab session.

List of Essential Linux, Emacs and Debugger Commands Getting Started: To login, type your username (Your roll number in lowercase letters) at the Login: prompt, and your password (same as your username) at the Password: prompt. Open a shell window from Applications -> Accessories -> Terminal menu.

Linux Shell Commands: mkdir dirname Make a directory dirname rmdir dirname

Remove the directory dirname

cd dirname

Change the current working directory to dirname

cd ..

Change the current working directory to the parent directory

cd ~

Change the current working directory to your home directory

pwd

Show your current working directory

mv srcfile destfile

Rename the srcfile as destfile

cp srcfile destfile

Copy one file, srcfile to destfile

cp srcfile(s) destDir Copy many file, srcfile(s) to destDir rm -i file(s)

Delete file(s)

ls -l

List files in the directory with their details (size, time of creation)

gcc –o prog prog.c Compile the C program in the file prog.c and create the executable file prog gcc –g –o prog prog.c Compile the C program in the file prog.c and create the executable file prog that can be used for debugging with gdb ./prog

Run the program prog

Special characters in file and directory names: * - wildcard matches any string; ? - matches any single character; ~ - your home directory

Gedit Editor: Gedit is a popular text editor. Launch gedit by clicking on Applications->Accessories ->Text Editor, or from the command line by typing gedit. It is a graphical editor and if you are familiar with MS Word or Wordpad, you will find the navigation familiar. gedit provides syntax highlighting capabilities for many file types including .c and .h files. Note that syntax highlighting does not work on new files with new names. If your file name has an extension like .c or .h, gedit automatically colors the source code. You can open multiple files in multiple tabs. It is quite customary for programmers to have the .c and .h files open at the same time. Online help is available by clicking on Help -> Contents.

Useful Commands in gedit: File -> Save As filename

Save the content in the file filename

File -> Save

Save the content in the current file

File -> Open

Open another file in a new tab

File -> Close

Close the file in the current tab

Ctrl + C

Copy the blocked text

Ctrl + X

Cut the blocked text

Ctrl + V

Paste the marked block

File -> Quit

Exit gedit

Writing Programs in gedit: Section 7 of online help deals with various programming features available in gedit. Edit -> Preferences brings up a menu that has plenty of options for editing programs. The options are shown in multiple tabs. 1.In the View tab, you can choose to display line numbers and highlight the current line. Also, turn on the option for showing you matching brackets. 2.In the Editor tab, change the tabspace to 4 and choose to insert spaces instead of tabs. Also, enable auto-indentation for formatting nested loops and functions neatly. 3.There are plenty of plugins available in the Plugins section. You may find some of them useful. Your editor preferences are automatically saved and are stored across multiple sessions. When you open gedit the next time, these options are automatically turned on.

A Standard for C Code by Prof. Timothy A. Gonsalves Following a coding standard is part of professional programming. This enhances the readability of your code, it improves the quality and makes it easier for other programmers to read and modify your code. Names To make the code self-documenting, choose meaningful names for variables. Abbreviations may be used so long as they are widely accepted. A good test of names is: can you read your code to a fellow programmer over the phone? For names that consist of multiple words, capitalize the first letter of each word. Distinguish classes of names as follows: Functions, Macros, Types, Classes: First letter uppercase (eg. GetInput(), LengthType, Compute() ). Constants: All uppercase, separate words with '_' (eg. MAX_LINE_LEN, PI, VOTING_AGE) Variables: First letter lowercase (eg. roomMessDistance, inBuf, myId, windowHt, wallWidth) Names should differ in more than one character, especially if they are of the same type. E.g., for the transmit and receiver buffers, txBuf and rxBuf differ in only the first character which occurs on adjacent keys on the keyboard. txBuf and rcvBuf is a better choice. Use the following abbreviations to identify particular names: Type Ptr Fl Str Chr Tab Num Ctrl Cmd Cnt Que Len

Defined type (e.g. typedef struct {...} MsgType;) Pointer (e.g. bufPtr, msgPtr, pktPtr) Boolean (e.g. moreFl) String (e.g. promptStr) Character (e.g. inChr, outChr) Table (e.g. relayTab, relayTabPtr) Number (e.g. numCourses) ["No" could be confused with the negative] Control (e.g. CTRL_C) Command (e.g. LastCmd) Count (e.g. wordCnt) Queue (e.g. inBufQuePtr) Length (e.g. roadLen)

Internal Documentation Apart from external documentation such as pseudo-code, flow-charts, state transition diagrams, function-call hierarchies, and prose, the program files should contain documentation. Begin each file with a comment including the following fields: /******************************************************************* * sort.c – for sorting integers filename with one-line description * Purpose: uses bubble-sort algorithm... purpose in detail * Compilation: use the supplied makefile Instructions for compiling * Revision history: Chronological list of changes/bugfixes * A. Programmer, 7/7/77 * released version 1.0 * C. Debugger, 8/8/88 * fixed stack overflow with null input * Eager B. Eaver, 9/9/99 * added ANewProc() to support 3-D * Bugs: Known bugs/limitation/testing to be done * The program occasionally crashes when two users * access the database simultaneously during the new moon. **************************************************************/

Declare each variable on a separate line, followed by an inline comment explaining the purpose of the variable. Use char *inBuf; // buffer for received keystrokes char *outBuf; // buffer for text going to the printer

rather than char *inBuf, *outBuf; // input and output buffers If there are a large number of variables, group them in blocks by function, and alphabetically within each block. Note: temporary variables such as loop indices need not follow some of these rules. Preceding each function, include a comment block as follows: /******************************************************************* * GetInput - get input from the keyboard. * Args: Stores the string in the buffer buf, max size is bufSize * Returns: number of characters stored in buf * or -1 on error. * Method: a brief description if necessary. * Bugs: list known bugs and limitations * To be done: if anything ********************************************************************/ int GetString(char *buf, int bufSize) { ... } /* End of GetString() */

Within the body of the function, on separate lines at the start of each major block (if, while for, switch), describe briefly the purpose and peculiarities of the block. For obscure statements, include an inline comment. Avoid obvious comments such as: i++;

/* increment i */

Layout Indent the code according to the following scheme and use blank lines to indicate breaks in the flow

of control. This improves the readability. while (moreFl) /* The main loop, terminates when done */ { if (i == 2) DoSomethingAppropriate(); else DoSomethingElse(); for (j = 0; j < maxFile; j++) /* Mumbo-jumbo for each file */ { total += table[i].wordCnt; i = j + k; cnt = j – 1; } } /* while (moreFl) */

Useful Features Some C language features that will enhance the quality of your code: Header files: collect macro, type, constant and global variable declarations and prototypes for public functions in one or more .h include files. Never include code in .h files. Group logically related functions into separate .c files. Use a utility such as make to automate rebuilding the program. Information hiding: declaring a function static makes it private to he module (i.e., file) in which it is declared. Likewise for data. In a header file, define #define PRIVATE static and use it for private functions and data: PRIVATE int myCount; PRIVATE void LocalFunc(); Function prototypes: use these to enable the compiler to check for consistency of arguments. In a header file, include function prototypes for all public functions. Remember to use void for functions that do not return any value. Enumerated types: use enum rather than a sequence of #defines. This is less error-prone and enables the compiler to check type consistency. Type casts: use explicit typecasts to avoid warning messages from the compiler about operands of different types.

substitute x = 1, then PI/4 =

arctan( x) = 1−13 / 3+ 15 / 5 −17 / 7 + ...

You must take the desired digits of accuracy d as input and print the result of .

Practice Experiments Assignment 1 (along with A2) Write a program that takes your last and first name from keyboard and then prints it out. e.g Input : Narang Gagan Output : Gagan Narang Assignment 2 (along with A2) Write a program that finds the volume of a hemisphere. The radius is given as an input. Assignment 3 (along with A3) Write a program to determine whether a given number is positive, negative, odd or even using a single switch statement. e.g Input: 4 Output : Even Positive Assignment 4 (along with A4) Write a program that takes a number and prints the multiplication table of it as given in the following example. e.g Input : 5 Output : 5*1=5 5 * 2 = 10 . . 5 * 10 = 50 Assignment 5 (along with A5) Write a program which takes an array, A, of n integers and a number, k. The program should then create two arrays, B and C, where B contains the elements of A which are smaller than k and C contains elements of A which are greater than k. Values of A and the number k has to be fed by keyboard.

e.g, if the A contains [3, 4, 1, 7, 2, 8, 6, 11, 0, 9] and k has value 5, then, B contains [3, 4, 1, 2, 0] and C = [7, 6, 8, 11, 9] Assignment 6 (along with A6) Write a program with a function, getLCM(int, int) that takes two numbers and returns the LCM of two numbers. Assignment 7 (along with A7) Write a recursive function to display first 20 numbers of a Fibonacci sequence. In a Fibonacci sequence the sum of two successive terms gives the third term. Following are the first seven terms of the Fibonacci sequence: 1 1 2 3 5 8 13
