Run .exe from a c++ program

How can we do this. How can we run .exe from a c++ program.

Suppose I have a file located in C: name "abc.exe".

Now how will I execute this "abc.exe" file from a c++ program????????

Assuming Windows, this fires up notepad:

Code:

HANDLE open_notepad()
{
    STARTUPINFO si = {sizeof( STARTUPINFO)};
    PROCESS_INFORMATION pi;
    CreateProcess( "c:\\windows\\notepad.exe",
                   0, 0, 0, 0, 0, 0, 0, &si, &pi);
    return pi.hProcess;
}

Or perheps something like this if you do managed:

Code:

System::Diagnostics::Process::Start("C:\\abc.exe");

Managed is not C++. C++/CLI is a managed language, and usually they mean "native" C++.

You can also use the standard system() function, or you can use popen(), or one of the spawn() functions...
