Question

Languge C Code

Write a program that acts as an integer calculator that supports a single arithmetic operation at a time. The user should enter the calculation on a single line. The program should continuously accept new inputs before until the user submits a blank line (return). The program should support all of the following operations: +, -, *, /, % (modulo). It should not be necessary to use the math.h library. Your program should not produce any output except for the answers to provided expressions.
