Write a program that mimics a calculator. The program should take as input two integers and then 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 are below:

Example 1:

Input:

Enter the first number: 10

Enter the second number: 15

Enter the arithmetic operator: +

Output

10 + 15 = 25

Example 2:

Input:

Enter the first number: 5

Enter the second number: 6

Enter the arithmetic operator: *

Output

5 * 6 = 30
