A valid loop for pausing a program after it ends

Question

I'm a novice programmer and have been learning C++ recently, after some research in how to pause my program at the end I upgraded from

system.get(); 

to a

cin.ignore();   
cin.get();  

combo. Would I be better suited to writing an if loop to wait for input at the end to close out the program, I understand that later in my experiences pausing the program at the end will cause user errors at the end.

I'm looking for the better way to do this.

In general, you don't need a loop to wait for the User to press a key.

Try:

std::cout << "Paused.  Press ENTER to continue.\n";
std::cin.ignore(10000, '\n');

This does not rely on the OS having a "pause" command.

Note: you may need a loop if you are polling for a keypress. Detecting a keypress is an operating system function, and you need to use specific OS API.
