Hey guys I'm working on a Pythagorean Triple program.

In my program everything worked and I found all the possible Pythagorean triples below the value 500. Unfortunately I had repeats due to the fact that the legs of the triangle could just "swap" value. I tried to correct the problem by using a three dimensional array called "used." Because I have a maximum of 500 on each side of the triangle I had to use 500 three times in my boolean value "used." I think this is just too large a value for my compiler but maybe I did something wrong. Check it out.

Code:

void calculate()
{
	int side1 = 1;
	int side2 = 1;
	int hypo = 1;
	int triplecounter = 0;
	bool used[500][500][500] = {false};

	for (side1 = 1; side1 <= 500; side1++)	{

		for (side2 = 1; side2 <= 500; side2++)	{

			for (hypo = 1; hypo <= 500; hypo++)	{

				if (used[side1][side2][hypo] == false)	{

					if (used[side2][side1][hypo] == false)	{

						if ((hypo * hypo) == (side1 * side1) + (side2 * side2))	{

							used[side1][side2][hypo] = true;

							used[side2][side1][hypo] = true;

							cout << "A Pythagorean triple is " << hypo << " " << side1 << " " << side2 << "\n\n";

							triplecounter = (triplecounter + 1);

						}

					}
				}
			}
		}
	}

	cout << triplecounter << "\n\n";
}
