using c# Create a 5 function (+, -, *, /, and modulus) calculator. This calculator should loop until esc is typed. For example, I should be asked for num 1, then some operation (+, -, *, /, and modulus) to another num 2. Provide the results, and then provide a way to esc the program or do another operation (+, -, *, /, and modulus) to the result.
