trouble getting c program to execute another program

I'm mainly interested in the simple goal of getting a C program to

I just want to get a C program to do

c:\windows\system32\cmd.exe /k dir or c:\windows\system32\cmd.exe /k c:\windows\system32\cmd.exe /k dir

I found a windows C compiler.. called lcc-win32

Here is the code i'm using, at the moment just aiming at launching cmd.exe

#include <iostream>
#include <fstream>
using namespace std;
int main(){
    ifstream inFile;
    inFile.open("c:\windows\system32\cmd.exe");
    if(!inFile){

      cout<<"Cannot open file bish."<<endl;
      system("pause");
      return 1;
      }

    system("pause");
}

But i'm getting a lot of errors cpp: c:\cprogs\hw2.c:1 Could not find include file cpp: c:\cprogs\hw2.c:2 Could not find include file and others

Compilation + link time:0.0 sec, Return code: 1

I'm hoping to just have found some example code on the net that I can amend but I can't even get any such code to compile.

--added---

I found some example code, I figured out to make the \\ 'cos i've some experience programming.

#include <stdlib.h>

int main()
{
    system("c:\\windows\\system32\\cmd2.exe /v:on c:\\windows\\system32\\cmd2.exe /v:on");
    return 0;
}

and that seems to work.

You're opening the executable file, not executing it. Check out the "system" call.

First of all, you need to escape your slash characters. "\\" translates to a single backslash.

But from what it seems, you don't actually need to worry about that at all. I see that you are using the system command. You don't need to execute cmd.exe at all in order to use system. Try simply

int main()
{
    system("pause");

    return 0;
}
