Keyboard interrupt on Turbo C++ 3.1

My name is Andrea. I'm using Turbo C++ on an old PII 350 MHz with dos 7. I've written a while cycle which does something. I have to check a which letter of the keyboard has been pressed without checking it in the cycle in order to avoid it to slow down. Is there a way to set an interrupt like in arduino to stop the cycle only when a key is pressed? I've tried with bioskey(0) in the cycle but it slows it down too much....

You can use the getch() function in <conio.h>, which pauses program execution until one key is pressed, and returns the character of the pressed key.

Example:

#include <stdio.h>
#include <conio.h>

int main()
{
    puts("Hello World, press any key to continue.");
    getch();
    puts("Finished");
    

    return 0;
}

Note that <conio.h> is a non-standard library. The <conio.h> library and the function are also available in modern versions of Visual C++, but the function is called _getch().
