How is this code written?

Question

Write a program that receives a positive integer from the user and checks whether it can be written as a sum of two whole squares. If true, display the letter 7, otherwise display the letter N. Example: 26 = 5^2 +1^1

Answer 1

Make a nested for loop (similar to a bubble sort argo) that go from 1 to square root of the number., use two pow functions from the cmath header, add them together and test against the number.
(probably easier to write the actual code than explain).
