Escape Sequences in C

Escape sequences are basically control characters used for formatting the output. These are combinations of a backslash and a character in lowercase. We have already used “\n”, which shifts the curser to the next line. Table lists the escape sequences defined in C language.

Illustrates application of some escape characters.

#include<stdio.h>
int main () { 
 printf("\a Hello!\nHow are you?\n"); 
 printf("I am learning C.\n"); 
 printf("\tAm I physically fit?"); 
 printf("\nAm\tI physically" " fit?\n"); 
 return 0; 
} 

The output of this program is as given below. Because of code “\a” you will hear a beep sound. Compare the spaces specified in the code with those obtained in the output.
