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.)
