I am a Computer Science and I am having a problem on writing this perl program for one of my classes. i haven't taken perl in about two years and do not remember how to set the syntax up or execute the program. Am I suppose to use C++? The class that I am taking is Web Applications. The program states the following:

A right triangle can have sides that ate all integers. The set of three integer values for the sides of a right triangle is called a Pythagorean triple. These three sides must satisfy the relationship that the sum of the squares of two of the sides is equal to the square of the hypotenuse ( famous a^2+b^2=c^2 formula). Find all Pythagorean triples that are not larger than 500 for side, side2, and hypotenuse. Use a triple nested for loop that tries all possibilities.

I do not need the full program. I just need to know the syntax to set the triples up and how I would execute the program.
