input: length of side -- int

output: perimeter -- message to stdout

Write a C++ program that accepts a single numeric value as the length of the side of an equilateral triangle or the length of a square.

Compute the perimeter of each one by using the formula:

perimeter = 3 * side for the triangle and

perimeter = 4 * side for the square .

The program dialog should look like this:

Enter the length of a side (in inches): 50.1 The perimeter of as square w/ 1 side of length 50.1 = 200.4 inches The perimeter of an equilateral triangle w/ 1 side of length 50.1 = 150.3 inches
