How to INSTANT accept a value?

[CosminPerRam]

Hi forum, i want to know if there's a funtion to instant accept when i press any key. Thanks in advance for any tryes to fix my problem, sorry for my english, this isn't an homework, im beginner!

To understand How i want:

Normal:

cin >> a;
//Enter the value of a;
//Pressing "Enter" for sending it.
//And the code continue....  

How i need to be:

cin >> a;
//Enter only 1 key
//Instant accept without needed to press "enter key", something like skiping the "enter" key.
//And the code continue.....

I don't think there's a standard way to do this, but often the function is called getkey(). See if your development environment supports it.

Under Windows and with Visual Studio you can use _getch() - other compiler under Windows might support it too.
