Someone posted some C++ windows code for displaying marquee text and I thought well isn't that interesting. He incorporated notepad and a own bunch of other windows stuff that will never work in my Linux world, so I wrote my own code for Linux to display a text message that would scroll to the right in a never ending loop. Now this code was written quickly in the wee morning hours but here it is. Now I thought initially that this would be simple, but you know it was really quite difficult....G4143

You should try writing a program like this....scroll a text message to the right in a never ending loop

Code:

#include <stdio.h>

#include <stdlib.h>

#include <unistd.h>

#include <stdbool.h>

//marquee

int mystrlen(char *s)

{

    int i = 0;

    while (*s++)

        ++i;

    return i;

}

char msg[] = "this is the message to display forever and ever and ever!";

int main(int argc, char**argv)

{

    int i;

    int len = mystrlen(msg);

    int start = len - 40;

    int istart = start;

    system("clear");

    while (true)

    {

        --istart;

        for (i = 0; i < 40; ++i)

        {

            if ((istart + i) >= len)

            {

                fputc(msg[(istart + i) - len], stdout);

            }

            else

            {

                fputc(msg[istart + i], stdout);

            }

        }

        if (istart == 0) istart = len;

        fflush(NULL);

        sleep(1);

        system("clear");

    }

    exit(EXIT_SUCCESS);

}

I have Windows, but i got used to translating, and i solved the problem . . . i didn't have library included !
