C++ || Find The Prime, Perfect & All Known Divisors Of A Number Using A For, While & Do/While Loop This program was designed to better understand how to use different loops which are available in C++.

This program first asks the user to enter a non negative number. After it obtains a non negative integer from the user, the program will determine if the inputted number is a prime number or not, aswell as determine if the user inputted number is a perfect number or not. After it obtains its results, the program will display to the screen if the user inputted number is prime/perfect number or not. The program will also display a list of all the possible divisors of the user inputted number via cout.
