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.
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");
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.
