How to make this keyboard shortcut work as many times as I want?

I am new to programming and also to stackoverflow and C++ is a very complicated language so please help help me here because I can't figure this out

#include <shlobj.h>
#include <shlwapi.h>
#include <objbase.h>
    #include<iostream>
    #include<conio.h>
    using namespace std;
    int main()
    {

char key_press;
        int ascii_value;

        key_press=getch();
        ascii_value=key_press;
        if(ascii_value==32) {
        ShellExecute(NULL, "open", "C:\\Users\\Usman\\Desktop\\Folders-Files\\Performance\\code\\bat\\downloads-folder-organizer.bat", NULL, NULL, SW_SHOWNORMAL);
}
return 0;

    }

The above code is meant to run a file "downloads-folder-organizer.bat" when I press the spacebar by detecting ascii value of a pressed key. However I can only do this once because after that the program closes. I googled and googled but no one seemed to address this problem because they were all talking about keeping the console window from closing, infinite loops etc. Can anyone help me?
