today's day
the name of the program source file
the short description what this program is doing
list of the variables with the short description for each variable -
name, type, purpose (this part could be done in the program by adding
comment after each variable declaration).
- You should be in lab3 directory under CSCI151 directory
- Problem 1 (50 points): Write a C program lab3Test1.c
that reads four integers and caclulates the sum, product, and the average of
the input numbers. Since, we are working with the integers your average will be
the integer part of the real average value. You don't need to use decimal point
arithmetics in this program. The output of the program will include: your name
and the
caclulated results with the appropriate message. The results should be
printed on different lines.
- After you finished writing , compile (type: gcc lab3Test3.c)
and
run
(type: a.out) your program to check
that your program returns a correct output.
Run your program at least three times before you submit the printout of
the source file and show me the output.
Submission Step:
- Show me the output
- Print and submit
the source file (the program) by typing lpr -Pnetlaser
lab3Test1.c
- Program (50 points): Write a C program
lab3Test2.c
that reads two 4-digits positive integers. The program finds the sum
of the digits of the first input number and the product of the digits of
the second input number.
Submission Step
- Show me the output.
- Print and submit the
source file (the program) by typing lpr -Pnetlaser
