So, I'm writting a program that will call another program that i've already written and im getting some unexpected results when I compile..heres what i've got

CODE

#include <iostream>
#include <fstream>

using namespace std;

int main()
{

   system("create_file.exe");


    ...random other stuff....
     cout << "DONE" << endl;

    return 0;
}


I thought that you could use system() with program calls..but i guess i'm just not sure how to use it. This is the error i get upon compiling and executing

QUOTE

'create_file.exe' is not recognized as an internal or external command, operable program or batch file.


Any ideas on how to fix this?

Well, you can definitely use system() for making system calls. It passes the string argument to the command processor, which then executes it.

However, create_file.exe is not a standard command on any system that I am aware of. This would only work if you already have a program named "create_file.exe" that is on the path of the command processor, and that error is telling you that this is not the case. Have you created this executable somewhere? And what exactly is this call supposed to do?

create_file.exe was a c++ program that I wrote to basically create a file, insert a value then close. I created a shortcut for the EXE on my desktop. so do i need to include the path to my desktop in the call for create_file?

Thanks

The system call should include the path to the executable, not the shortcut. Unless, of course, the executable is already in the same directory as the calling program.
