Program Looping question

**BIt_toRreNt** · 02-10-2005

Hi I just started to learn C++ so please forgive me for any newbie things I say during this post. I went through the tutorial on this site and made it through the beginners section. What I didnt learn was how to loop programs like calc.exe over and over again as a joke or to make my own startup folder. Please any suggestions on how to set this up is appreciated. Thank you

Infinite loops are simple with a while or do-while loop.

Code:

#include <iostream>

int main()
{
   while(true)
   {

       std::cout << "Stuff happens here" << std::endl;
    
   }
}

Code:

int main()
{
    for(;;)
    {
        //put your program in here
    }
    return 0;  //this line will never be reached
}

how do you mean 'make my own startup folder'? if you mean the folder 'my documents' points to in windows, I believe that's written in the registry somewhere. in linux, type usermod -d path username

What I meant by start up folder was to make a program using C++ that could open up all my rendering and cad programs instead of having to select the ones i need all the time. Being as lazy as i am I like to have light wave rhino and Bryce open instead of me opening each one at a time. I dont want to put them in windows start up folder becasue i dont go on my computer everytime jus to do cad and rendering. So i just wanted to make a program that could auto execute those programs. Maybe I should just make a quick batch file and stop worrying how to make it in C++ Thanks for your guys help by the way.

assuming you're using windows, know exactly where these files are, and simply double-clicking them will open them the way you want, you can use system calls:

Code:

#include <cstdlib>

int main()
{
    system("start path to file");
    system("start path to second file");
    return 0;
}

be warned, however, that this introduces the possibility of a major security breach. if you're only using this on your machine, this shouldn't be a problem though. also note that if you move the files you'll have to change your code and recompile the program.

perhaps a better way of doing this is writing a batch script:

Code:

@echo off
start path to first file
start path to second file

save that as something.bat, put it on your desktop, and run it...

edit: I didn't even read the last line of your post until just now, but yes, that would be the better way to do it...
