    Simple c++ program

    I am trying to figure out how to make a program perform the following funtion "cpc -B *.cpc -O 1" where 1 is the directory... What that function does is converts .cpc files into .tif files... It would be ran out of my c:\cpc folder and I would like to be able to choose a directory to convert the new .tifs in to.... Can anyone recommend the best way of going about this? I am very new to c++ and trying to read all I can..

    Are you looking for a program that already exists?

    If you are planning on writing one yourself, I think it would be a bit much for a beginner.

    Can you write it yourself?

    I'm sorry for explaining it bad.. I already have the program that converts them.. But as it is I have to type out cpc -B *.cpc -O 1 every time, and I want to make it to where all I have to do is double-click an icon on my desktop and have it pop up and ask something to the effect of "what directory would you like to save your files in?" and have it make one...

    Put together as something like this.
    Code:
    #include <stdio.h>
    #include <stdlib.h>
    #include <string.h>
    
    int main(void)
    {
       char path[FILENAME_MAX];
       fputs("path? ", stdout);
       fflush(stdout);
       if (fgets(path, sizeof path, stdin))
       {
          char command[sizeof path + 30];
          char *newline = strchr(path, '\n');
          if (newline != NULL)
          {
             *newline = '\0';
          }
          sprintf(command, "cpc -B *.cpc -O %s", path);
          puts(command); /* to see the created command line */
          system(command);
       }
       return 0;
    }
    Example:
    path? c:\
    cpc -B *.cpc -O c:\
    Like that?

    You can normally achieve that with a little bit of batch file programming.
    It's very easy if your shell is bash though.
    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.
