C++ Problem

This is my C++ program why does the sqrt() function not work correctly
#include <iostream>
#include <cmath>
using namespace std;

int main ()
{
    int a;
    cout << "Input a";
    cin >> a;
    int b;
    cout << "Input b";
    cin >> b;
    int c;
    cout << "Input c";
    cin >> c;
    int n;
    n=(-4.00*a*c);
    int q;
    q=sqrt(n);
    int d;
    d=q+b*b;
    int r;
    r=(-1.00+d)/(2.00*a);
    int s;
    s=(-1.00-d)/(2.00*a);
    if (r>0.00)
    cout << "(x+" << r <<") ";
    else if (r<0.00)
    cout << "(x" << r <<") ";
    if (s>0.00)
        cout << "(x+" << s <<") ";
    else if (r<0.00)
        cout << "(x" << s <<") ";
}

What do you mean? Your program runs perfect for me.

Probably because you used int to hold it instead of double.

Oh. It must be terminal that is messed up

YHBT

float InvInvSqrt(float x)
{
    union {
        float f;
        int i;
    } tmp;
    tmp.f = x;
    tmp.i = 0x5f3759df - (tmp.i >> 1);
    float y = tmp.f;
    return (1/(y * (1.5f - 0.5f * x * y * y));
}

NOW YOU'RE THINKING WITH QUAKE

Probably because you're picking positive values for a and c

sqrt works best when code is wrapped in code tags.

>>6
Unions, fucking magic.

>>9
They're like unicorns but without the c and r.

>>10
They're like onions with a s/u/o/i, but magic.
