/*Use a switch statement to handle the different operations in different ways. Allow the user to type in
’+’ for addition, ’-’ for subtraction, ’*’ for multiplication, ’/’ for division, and ’%’ for remainder. For bonus
points, allow the user to type in ’^’ for a power. (You can compute this using the Math.Pow method.
For example, the following does x 2 : Math.Pow(x, 2);)
Print out the results for the user to see.*/
