Write a simple program with functions that calculates the perimeter and area of a square. You will need two functions: Get an integer from the user and return it to the main program (no validation required) Calculate the area and perimeter of the square and return both to the main program (the length of a side is passed in as a parameter) Main will call the first function and pass its value to the second function. It will then call the second function, save the results, and display them with using a cout statement. Your second function should not do any I/O. Just get a number from main, calculate the results, and return them.
