Triple For Loop

Question

I must use a triple for loop to display all the possible pythagorean triples by using the brute force method. My program just prints 2 for what seems like an infinity.

#include <iostream>

using namespace std;

int main()
{
int count = 0;
int side;

cout << "Side 1\tSide 2\tHypotenuse" << endl;

for (int side1 = 1; side1 <= 500; side1++){
cout << side1;
for (int side2 = side1; side2 <= 500; side2++){
cout << side2;
for (int hypotenuse = side2; hypotenuse <= 500; hypotenuse++){
hypotenuse = (side1 * side1) + (side2 * side2);
cout << hypotenuse;

}
}
}
cout << "A total of " << count << " triples were found." << endl;

system("pause");
return 0;
}

Answer 1

#include <iostream>
using namespace std;

int main()
{
int count = 0;
int side;

cout << "Side 1\t\t Side 2\t\t Hypotenuse" << endl;

for(int side1 = 1; side1 <= 10; side1++)
{
for(int side2 = side1; side2 <= 10; side2++)
{
for(int hypotenuse = side2; hypotenuse <= 10; hypotenuse++)
{
side = (side1 * side1) + (side2 * side2);
cout << side1 << string(10, ' ') << side2 << string(10, ' ') << side << endl;

}
}
}
cout << "A total of " << count << " triples were found." << endl;

return 0;
}

Well actually inside the inner most for loop you are changing the value of hypotenuse variable, that's why loop was infinite.
I changed the hypotenuse variables with side variable which was unused.
Also I changed the 500 to 10 in each for loop for testing purpose, you can change it back to 500 it will work fine.

Answer 2

It prints a character n times.
In line string(10, ' ');
It prints 10 spaces

Answer 3

Can you please explain what the string(10, '') is?
