When running any c++ program that requires an input value(see below), bloodshed will automatically close the console window once the user hits enter. I thought that the

(Toggle Plain Text)

cin.get();

line might work, but no luck. Any suggestions?

(Toggle Plain Text)

#include <iostream>
using namespace std;

int main ()
{
    int i;
    cout << "Please enter an integer value: ";
    cin >> i;
    cout << "The value you entered is " << i;
    cin.get();
    return 0;
}

If cin.get() doesn't work, that means you have more in the buffer than you've read. Consequently, cin.get () takes part or all of it, and having done its job, returns. Execution then continues to the end of the program. Use cin.sync () prior to the cin.get () to discard the contents of the buffer.

Or just do this:

#include <iostream>
using namespace std;

int main ()
{
    int i;
    cout << "Please enter an integer value: ";
    cin >> i;
    cout << "The value you entered is " << i << endl;
    system("pause");
    return 0;
}

Works like a charm. Thanks alot guys.

system ("pause") is, however, not portable. If that's of no consequence to you, go for it.

Would cin.sync () be better to use then?

cin.sync is for synchronizing, it has nothing do with pausing the program at the end.

DaWei · Jan 25th, 2006, 2:59 PM

cin.sync () followed by cin.get (), as stated in my initial response.
