Thread: Keep running program and 'int' problem

I'm using this program in C++ to calculate wind chill:

Code:

#include <cstdlib>
#include <iostream>
#include <math.h>

using namespace std;

int main(int argc, char *argv[])
{
    cout << "Wind Chill Calculator...\n" ;
    cout << "By William Seed\n" ;
    int temp, vel;
    int ch;
    cout << "Enter the temperature:";
    cin >> temp;
    cout << "Enter the wind speed:";
    cin >> vel;
    ch = 35.75 + (.6215 * temp) - (35.75 * pow(vel,.16)) + (.4275 * temp * pow(vel,.16));
    cout << "The wind chill is: ";
    cout << ch;
    cout << "\n";
    system("PAUSE");
    return EXIT_SUCCESS;
}

I have two problems:

1. (most important) I want this program to keep running until I tell it to stop (using imput as yes or no.
2. If I try to use a decimal for 'temp', then the program ends...

I'm new, so no flaming, please.

Thanks in advance,

Will
