Problem Statement

APC-PRAC-039.c

Write a C program to print all unique combinations of three numbers (a, b, c) such that: 1 ≤ a, b, c ≤ 30 and a² + b² = c² (Pythagorean triplets)

Source Code

#include <stdio.h>

int main()
{
    printf("a² + b² = c² :  ");
    int i, j, k, sq1, sq2, count = 0;
    for (i = 1; i <= 30; i++)
    {
        sq1 = i * i;
        for (j = i + 1; j <= 30; j++)
        {
            sq2 = j * j;
            for (k = j + 1; k <= 30; k++)
            {
                if (sq1 + sq2 == k * k)
                {
                    printf("(%d, %d, %d)  ", i, j, k);
                    count++;
                }
            }
        }
    }
    printf("\n\nCount: %d\n", count);
    return 0;
}
