    How to create a scrolling cmd window?

    Hello,

    I have a question about compiling with MS-DOS. For example, if I execute this code:
    Code:
    #include <stdio.h>
    int main()
    {
        int k;
        
        system("cls");
    
        k = 0;
    
        while ( k < 20 )
        {
             printf("The Value of k = %3d\n\n",(k+1) );
             k = k + 1;
        }
    
        printf(\n\n);
    
    }
    I achieve this output:

    As you can see, there is no scrolling bar and I can't even see the numbers above 11. Is there a way to fix this in the compiler settings or the code? Thanks.

    You're obviously running the program from inside some kind of IDE... check it's settings... or... open cmd.exe and run the program from the OS...

    I have actually found the answer on another forum, superuser.com. Here it is as follows:

    ...but here in XP land (and for a few Windows versions before that) you can get to the properties you're looking for either by right-clicking the icon/shortcut you use to open the command prompt, or by left-clicking the icon in the top left corner of the command window. In Properties, go to the Layout tab and increase Screen buffer size: Height to some big number like 1000. If you do it that last way, when you click OK to exit the Properties dialog, it will ask if you want to make the settings the new default. Some variation on all that likely exists in Windows 7.
    Thanks.

    One would not suspect that since in Win7, Vista, Xp and win2000 the default buffer size has always been 50 and the screen height has always been either 100 or 300.

    If you didn't know those settings were there... how'd they get changed?

    My net book was brought pretty recently and I am the only user so I think those settings were the default, again pretty surprising for win Xp and up.
