Question

Here’s the code

#include <iostream>
#include <cmath>

int main()
{
    float c, d;
    for(int a = 1; a < 1000; ++a) {
        for(int b = 1; b < 1000; ++b) {
            c = (a*a) + (b*b);
            c = sqrt(c);
            d = a + b + c;
            if(d==1000) {
                std::cout << a << "," << b << "," << c << std::endl;
                break;
            }
        }
    }
    system("pause");
    return 0;
}

Cannot run it on my system Dev-C++ 4.9.9.0.

But when tried it in an online compiler and it gave the output but with the following output:

200,375,425
375,200,425

Disallowed system call: SYS_fork

Answer 1

I’d imagine that the online compiler disallows calling

system("pause");

since that creates a new process. Try removing that line and see if it runs better!

Another way of pausing at the end of the program would be to include iostream at the top, and then wait for input at the end, before returning:

//At the top
#include <iostream>

// Before return 0;
std::cin.get();
