Thread: Split PDF with GS and a little addon

Hello together
Please i have here a little toy to learn and for "possible" usage.
the goal are that i need to split me pdf document to single sides.

with the Appl GS, i can this do without problem, but i need to edit
any time my batch script. here i was thinking with this little app
that i have here i can do any workaround, and ask how meny pages you have, and this will do automatic this split.

Please are this a possible realistic way??
thanks meny time for your possible help
regards and thanks
Mauri

Code:

#include <stdio.h>
#include <process.h>


int main()
{
    int choice=0;


    printf("\n******* this App will split your PDF in single PDF Sites **********\n");
    printf("1. how meny pages have your PDF 1\n");
    printf("2. how meny pages have your PDF 2\n");
    printf("3. how meny pages have your PDF 3\n");
    printf("4. how meny pages have your PDF 4\n");
    printf("5. how meny pages have your PDF 5\n");
    printf("6. how meny pages have your PDF 6\n");
    printf("7. how meny pages have your PDF 7\n");
