\a

The way programmers can annoy the hell out of the people who run their programs. It is an escape character that is known as the "bell character" that makes the internal speaker in your computer beep. '\a' can be used in many programming languages, including C, C++, and PASCAL.

Below is an example written in C that will make your computer beep forever (or at least until you close the program).

#include <stdio.h>
int main()
{
for(int i=1;i>0;i++)
printf("\a");
}
