how to shutdown system c++

To shutdown a system using C++, you can use the system() function and pass the appropriate command as an argument. Here's an example:

#include <cstdlib>

int main() {
    system("shutdown -s -t 0");
    return 0;
}

This code will call the system() function with the command "shutdown -s -t 0", which instructs the system to shut down immediately (-s) without any delay (-t 0).

Please note that shutting down a system programmatically can have serious consequences, so use this code with caution.
