Escape Sequence in C

An escape sequence is a sequence of characters that does not represent itself when used inside a character or string literal.

In C, all sequences consist of two characters, the first of which is the backslash, \ (called the "Escape character"); the remaining characters determine the interpretation of the escape sequence.

ESCAPE SEQUENCE	MEANING
\a	Alarm or Beep
\b	Backspace
\f	Form Feed
\n	New Line
\r	Carriage Return
\t	Tab (horizontal)
\v	Vertical Tab
\\	Backslash
\’	Single Quote
\”	Double Quote
\?	Question Mark
\nnn	Octal Number
\xhh	Hexadecimal Number
\0	Null

Example programs of some of the commonly used escape sequences:-

1. '\n'

#include <stdio.h>
int main() {
    printf("Hello,\n");
    printf("How are you?");
    return 0;
}

2. '\t'

#include <stdio.h>
int main() {
    printf("Hello,\t How are you?");
    return 0;
}

3.  ' \b '

#include <stdio.h>
int main() {
    printf("Hello,,\b How are you?");
    return 0;
}

4. ' \v '

#include <stdio.h>
int main() {
    printf("Hello,");
    printf("\v How are you?");
    return 0;
}

5. ' \\ '  ,  ' \' '  ,  ' \" '  &  ' \? '

#include <stdio.h>
int main() {
    printf("Slash :- \\");
    printf("Single Quote :- \' ");
    printf("Double Quote :- \" ");
    printf("Question Mark:- \? ");
    return 0;
}
