    End of Program

    This is a total noob question but when I run a simple program how do I keep my program window open until I enter a character from the keyboard. Like I said, I'm new at this and thought I might come here for help. Thanks in advance.

    Nevermind. I'm kind of slow at this, but I figured it out. Thanks.

    for example
    Code:
    #include<stdio.h>
    #include<conio.h>
    
    int main()
    {
       printf("input a char to exit the program\n");
       getch();
       return 0;
    }
    Nana C++ Library is a GUI framework that designed to be C++ style, cross-platform and easy-to-use.

    Thanks for the response.

    Well I thought I fixed it.

    I've tried the

    Code:
    #include <stdio.h>
    main()
    {
        char d1, d2, d3, d4;
        int x;
        scanf("%d%c%c%c%c", &x, &d1, &d2, &d3, &d4);
        printf("%d%c%c%c%c", x, d1, d3, d2, d4);
        getchar();
        return 0;
        
    }
    but it doesn't keep the DOS window open so that I can view the input numbers.

    scanf left a newline in the stream and getchar read it. Throw in another getchar to eat the newline and you'll be set.
    My best code is written with the delete key.
