A problem with C++ program

At4ri · 06-13-2009, 12:01 PM

I have a bit of a problem with my C++-programs. I get them to work and all that but when I want them to display an end result it goes wrong. It's not that it doesn't work it's just that the program closes itself before i get to view the result. Basicly i cant get the program to pause before closing down.

----------------------------------------------------

Ex
// convert.cpp
#include <iostream>
double stonetokg(double);
int main()
**
using namespace std;
double stone;
cout << "Input weight in stone:";
cin >> stone;
double kilo = stonetokg(stone);
cout << stone << " stone is ";
cout << kilo << " kilogram." << endl;
cin.get();
return 0;
}

double stonetokg(double sts)
**
return 6,35 * sts;
}

----------------------------------------------------

Don't know if it's a problem caused by vista or not.

Edit: re-read your code. How are you executing the program?(from an IDE? just through windows? command prompt?)...

Re-Edit:
Found the problem:

Code:

cin >> stone;

You don't specify that the user has to press enter anywhere, so the last cin.get(); just finishes the user input for the above line...

Change it to:

Code:

cin >> stone;
cin.ignore();//ignores the enter and takes the users input

Cheers,

Thanks a lot jamie for the help. Tried it and it worked. I open it in cmd since its a console application.

Btw it looks like this:
