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 takes two integer parameters, called start and end. The function determines and prints all the perfect numbers between start and end (e.g between 1 and 100). Print the divisors of each perfect number to confirm that the number is indeed perfect. In C++
