Donot use link to tutorial of this site.It is not working.
thanks

If ur OS is Windows then forget abt it. It never worked for me either.

I'm not sure if you are getting a compile time or runtime error, but I believe system() is part of stdlib.h. Try including that.

If that does not solve your problem, please give a description of the error you are receiving.

Also, your current working directory might not be what you think it is. Consider using the full path to 'myprogram.exe', instead of assuming it will be found.

Or have the executable file in the directory of the other program.

Try omitting the .exe off of the end.

That wont do it. How about Try; "Giving some useful information such as what isnt working... Some errors maybe? Some symptoms? Throw us a bone!"

The problem is that you are just saying run this program when the current working directory is somewhere else.

Do this:

Code:

---

#include <stdio.h>
#include <stdlib.h>

int main()
{
  system("c:\\system\\program.exe");
  return0;
}

That should work

And don't put in stdio.h because you do not need it... ;)

!!!!!ANSI!!!!!!

Code:

---


#include <stdlib>
using namespace std;  // or using std::system

int main()
{
    system ("cls");
    system ("pause");
    system ("ping http://www.yahoo.com");
    system ("yourfile.exe");
    system ("pause");
    system ("cls");
    return 0;
}

Go back to the C++ board. We don't use name spaces or "<stdlib>" here.

LOL...

Sorry about that... followed it in from a link. ;)

Do you use system? I thought that was a C++ standard function?????

Guess it is... so woops!!! :D

Many functions that are standard to C are also in C++. Just like the syntax is the same. Basicly C++ is an extension of C, and as such, it has many similar functions and behaviour.
