Write a program that mimics a calculator. The program should take as input

two numbers and an arithmetic operation $(+,-,*,$ or $/)$ to be performed. It

should then output the numbers, the operator, and the result. $($For division,

if the denominator is zero, output an appropriate message.$)$ Some sample

outputs follow:

$3+4=7$

$13*5=65($use C# in visual studio$)$
