Code:
#include <iostream>

using namespace std;

int sqrt(int a, int b)
{
    for (b = 1; b*b <= a;) {
        b = b + 1;
    }
    return b - 1;
}
int main()
{
    int n = 36;
    int n2;
    
    cout << sqrt(n, n2) << endl;
    
    system("PAUSE");
    
    return 0;
}

I know, I know... My sqrt function really does suck, but I'm not a math genius. Anyway, just didn't want to use math libraries. (Don't make fun of me!) Sad
