opening a file in dos

how do you make dos open a seperate file like ms paint for example

The simplest way without knowing what exec-type functions your compiler supports would be

Code:

---

system ( "mspaint" );

---

what would be the whole program code for that?

Code:

---

...
#include <cstdlib>
...
int main()
{
  ...
  system("[enter system call here]");
  ...
}

---

He okay i'm a newb let me tell you that. Anyway, i find this a very unclear question. Open in dos?
C:\map\map\program.exe

c.c

That would be

Code:

---

<cstdlib>
using namespace std;

int main()
{
  system("C:\\map\\map\\program.exe");

 return 0;
}

---

Note the escaping(sp?) of the backslash. I think a forward slash will work too, but I'm not sure.

If you are in pure DOS or a DOS session (NOT available in XP) then you can call DOS int 21h and open a file via DOS or you can execute a dos interrupt from C which will automatically call DOS for you.

DOS has specific functions for opening child processes although they are somehwhat limited since it was never designed to be a multi-tasking OS.
