Lab 04: To demonstrate command of I/O
Note: Students must demonstrate their lab in the following week of March XXXXXXXXXXth, 2021 to get the
grade. This lab is worth 20marks. A Missed demonstration will result in 25% grade deduction. Late
submission and late demonstration to the lab is welcomed but with a loss of marks. That is, you do not
earn full marks for late submission. 10% penalty for every day late up to 50%. Work will not be ac-
cepted after 10 days.
You must talk to your lab professor in case of any unprecedented situation which may result in late
submission.
You are required to submit the screenshot of your terminal showing successful execution of the pro-
gram (including relevant display messages or output statements) along with properly commented (as
per assignment submission standards doc on BrightSpace) .c file and makefile of your code.
Problem Statement: Collaborating Plotter
You are asked to write a C program coPlot.c that will cooperate with the end-user, accept
keyboard input during execution, and output the results based on the user's commands.
More precisely, your program will support the following "commands" typed-in by the end-user
during runtime:
1> Bit operations:
Logic Gate Operands Manipulation
it_or
int2> bitwise OR of the two specified integers
it_and
int2> bitwise AND of the two speci-fied integers
it_xor
int2> bitwise XOR of the two specified integers
it_shift_left
k> shift the bits of the integer s k bits to the left
it_shift_right
k> shift the bits of the integer s k bits to the right
2> String Operations:
everse
- reverse of the specified string
3> Termination:
exit - stop the execution of your program

When your program is started, it should ask the user for a command to run. Once the user
types-in the command, your program should do the processing and print the results to the
screen. This shall continue until the user types the exit command, at which point your program
terminates.
Here is an example run:
• :~> ./coPlot
Please enter a command to run.
it_or 15 25
31
Please enter a command to run.
it_and 15 25
9
Please enter a command to run.
it_xor 15 25
22
Please enter a command to run.
everse hello
olleh
Please enter a command to run.
everse CST_8234_Intro_to_C_Prog
gorP_C_ot_ortnI_4328_TSC
Please enter a command to run.
exit
Good Bye!
Useful Tips:
• Use the function atoi, defined in stdlib.h, to convert string input from the user to an
integer for the bitwise operations.
• chars have numerical values in ASCII (for example 'a' has the numerical value 97, 'A' has
value 65, and '0' has value 48 in ASCII). Additionally, sequential characters have sequential
numerical values (for example, 'b' has value 98 and 'c' has value 99). Thus, to get the
character forward from char c, you can just do c+1.
Submission Instructions
• You must submit your source code (.c file) and makefile in the assigned submission folder on
BRS section 010 (activities Assignments). We don’t need your entire project folder.
• You will need to demo this code in your lab session, the week of March 22-26th, 2021. During
demonstration, you must be able to answer any questions related to the assessment.

• Your programs will be compiled with GCC and tested on WSL. Keep in mind that your assign-
ment testing will be on fixed environment and therefore your applications is expected to run
on that.
Marking Scheme

Academic Integrity Reminder
Remember that you may have general discussions about how to approach this problem with your
peers, but you should work on the final solution by yourself alone.
