How to open a notepad in C++ then still continue using the c++ program even when the notepad is open? I tried system("filename.txt") But I can't continue using the c++ program unless I close the notepad file. is this possible?

    Not possible portably. Each OS is going to need different code. Looks like Boost has a library for it, as usual, or at least almost in this case, as it's [not quite in there](http://stackoverflow.com/questions/1683665/where-is-boost-process). – chris Mar 18 '15 at 15:53
  • Spawn a thread and open the editor from there. But chances are, once you're looking at `system()` in your C/C++ code, your program is FUBAR anyway. There are only very few meaningful use cases for `system()`, and I have not really come across one yet in the wild. ;-) – DevSolar Mar 18 '15 at 15:57

As an alternative, you can use ShellExecute like this:

ShellExecute(NULL, "open", _T("notepad.exe"), NULL, NULL, SW_SHOWNORMAL);

You didn't write on what OS you're on but on windows you can use 

system("start notepad.exe");

for example:

#include <iostream>

int main (void){

    system("start notepad.exe");
    std::string x;
    std::cin>>x;
    std::cout<<x;
    return 0;
}

the trick is the "start" command rather then just the filename

  • -1 for system(). Causes a lot of trouble including potential security vulnerability, unintended behavior and program possibly being recognized as a virus. – Spook Apr 14 '22 at 09:52
