#include <cstdlib>
#include <iostream>
using namespace std;

int main() {
double ctemp, ftemp;

cout << "Input a celsius temp and press ENTER: ";
cin >> ctemp;
ftemp = (ctemp * 1.8) + 32;
cout << "Fahrenheit temp is: " << ftemp;

return 0;
}

Its meant to convert Celsius temp to Fahrenheit.....but I see it works It just closes really fast.

Add cin.get() or getch() before return 0; That way you wil need to hit a key before it closes.

Really popular one is system("pause");

But the problem with system ("pause") is that it's windows only. Also i heard it's less efficient than just cin.get(); etc.

The problem with system("pause") is that is has to go allocate memory in your actual system, then pause everything your doing. This can add up to slower run-time in the long run.

seems to me if you want to pause it, runtime isn't a big issue. Anyway I didn't know that. I will add it to my code from now on.

That didn't work and I had too add ";" b4 return or it would compile after i did what you said? .....mind post the code whole so I see if i am doing it right?

IT WORKED ...thx guys
