I was just wondering if anyone knew how i could make a beeping come from the computer when the user presses a key(such as enter)?

For example, a quiz and when they finish it(and press enter), a beeping comes from the computer before DOS closes.

You gotta be kidding me, please don't use those annoying beeps in one of your programs, I'll delete your program, hack your website and call the cops to storm your house

You can disable the beeps if they annoy you, you know. They're useful to provide audible feedback or to grab the user's attention in the absence of more advanced methods for doing so.

..hi, i'm sorry for break into it...

...but will someone explain the parsing of that

(Toggle Plain Text)

std::cout << anything

?? - just now a 'little' on c, so as i would try it would look like this

(Toggle Plain Text)

#include <stdlib.h>
char  *anything;
void main () {
    wirte ( 1 ,  *anything , strlen (anything)) }

...is that correct?

No it's not, and why not use printf?

(Toggle Plain Text)

#include <stdio.h>
char * anything = "hi";
main()
{
	printf("%s\n", anything);
}

I'd still just use C++.
