c - This program sounds the bell!

Question

I'm a brand-new student in programming arena so I can't grasp this program written in my book that I have been following for a few days. The program is like this:

#include "stdio.h"

main()
{
 printf("a");
}

What does this program mean? Does this program mean that we could hear a ringing bell? I can't hear any ringing bell sound!!!

Answer 1

ASCII character 7 is the BELL character, and it's represented in C as a. Some terminals will produce a beep when this character is output on the terminal; nowadays, many don't. (I'm looking at you, Ubuntu.)
