An integer is said to be a perfect number if the sum of its divisors, including 1 (but not the number itself), is equal to the number. For example, 6 is a perfect number, because 6 = 1 + 2 + 3. Write a function isPerfect that determines whether its parameter (type int) is a perfect number and returns a bool. Use your function in a test program that prompts the user to enter the lower and upper boundaries for where to look for the perfect numbers and then outputs all perfect numbers in the given range (including the endpoints).
