Question

I have the same problem as mentioned in the linked question. The console window (in VS 2010) disappears immediately after running the program. I use a cin.get(); at the end of the main function, but the problem still remains. Any idea about the possible reason? You can check out the code in main:

int main()
{
    const int arraysize = 10;
    int order;
    int counter;
    int a[arraysize] = {2,6,4,45,32,12,7,33,23,98};

    cout<<"Enter 1 to sort in ascending order\n"
        <<"Enter 2 to sort in descending order\n";
    cin>>order;
    cout<<"Data items in original order\n";

    for(counter=0;counter<arraysize;counter++){
        cout<<setw(4)<<a[counter];
    }

    switch (order){
        case 1: cout<<"\nData items in ascending order\n";
                selectionSort(a, arraysize, ascending);
                break;
        case 2: cout<<"\nData items in descending order\n";
                selectionSort(a, arraysize, descending);
                break;
        default: return 0;
    }

    for(counter=0;counter<arraysize;counter++){
        cout<<setw(4)<<a[counter];
    }

    cout<<endl;
    cin.get();

    return 0;
}

link : C++ on Windows – the console window just flashes and disappears. What's going on?

Answer 1

My guess is that

default: return 0;

get executed.

EDIT:

You’re right, that’s not the issue. Read this.

The quick fix is:

cout<<endl;
cin.ignore(); // <---- ignore previous input in the buffer
cin.get();

But you might want to read the article for further info on the behavior.
