Description
Lab #3. Programming assignment (100 pts):
Write a computer program in C which will simulate a calculator. Your calculator needs to support the five basic operations (addition, subtraction, multiplication, division and modulus) plus primality testing (natural number is prime if it has no non-trivial divisors). Example of the output follows:
Calculator Menu:
- Addition
- Subtraction
- Multiplication
- Division
- Modulus (integers only)
- Test if prime (integers only)
- Exit
Please choose an operation: 2
Enter the first number: 18
Enter the second number: 20
18 – 20 = -2
Calculator Menu:
- Addition
- Subtraction
- Multiplication
- Division
- Modulus (integers only)
- Test if prime (integers only)
- Exit
Please choose an operation: 6
Enter the number to be tested: 22
Not prime: 2 x 11 = 22
Calculator Menu:
- Addition
- Subtraction
- Multiplication
- Division
- Modulus (integers only)
- Test if prime (integers only)
- Exit
Please choose an operation: 7 Good Bye!
You program MUST be bug-free, well commented (Including author information, program description, lab section, date, etc.)
