32-bit Calculator

Introduction:

The objective of this experiment is to create a simple 32-bit calculator.  The calculator will display a menu asking the user what operation they would like to perform.  The operations supported should be: Addition, Subtraction, Multiplication, and Exponentiation.  Once the user selects an operation, the program will ask the user for the values and perform the operation.  The multiplication and exponentiation operation must be implemented as a loop that adds numbers repeatedly. You are not to use the mul, imul, or pow functions to perform multiplication and exponentiation.  Once the program computes the value and displays the result, it should return to the original menu until the user chooses to exit.

I have many problem with coding nearly 129 errors, but I have reduce all the errors.

My partner name is Fredrick Jah.
