How to find pythagorean triplet for which a + b + c = 1000 in C++

Answer 1

#include <iostream>

int main()
{
    const int sum = 1000;
     
    for (int a = 1; a <= sum / 3; a++) {
        for (int b = a + 1; b <= sum / 2; b++) {
            int c = sum - a - b;
            if (a * a + b * b == c * c) {
                std::cout << "a = " << a << " b = " << b << " c = " << c;
            }
        }
    }
}
 
 
  
// (200 ^ 2 = 40000) + (375 ^ 2 = 140625) = 180625 = 425 ^ 2
 
 
  
  
/*
run:
  
a = 200 b = 375 c = 425
  
*/
