    If your needs are simple and a text based program, you can print a line with the line-feed character to simulate this. Here is an example

    Code:
    #define DOTS_10 ".........."
    #define SPAC_10 "          "
    int main(void)
    {
        for (int i=1; i <= 10; i++) {
            do_something();
            printf("%1.*s", i, DOTS_10);
            printf("%1.*s\r", 10-i, SPAC_10);        
        }
        printf("\nDone!\n");
        return EXIT_SUCCESS;
    }
    Each time you print \r the cursor goes to the beginning of the line and overwrites what was there before. So the result gradually completes to show the entire line of dots

    A more sophisticated approach is to use a GUI library which has classes and methods for drawing graphical progress bars to the screen. There are also text-based libraries which have these as well. Ncurses + CDK is one example for text mode.

    To create graphical progress bars, use a GUI library. Examples are Qt, GTK and on Windows you can use the WINAPI if you want. Try searching for winapi progress bar example for examples

    The last supported OS for bloodshed dev-c++ was windows 2000.

    Perhaps you should upgrade.
    Visual Studio Express 2012 Products | Microsoft Visual Studio
    smorgasbordet - Pelles C
    Code::Blocks
    Orwell Dev-C++ | Free Development software downloads at SourceForge.net

    Oh, and moved to the windows board.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
