What are escape sequences in C?

Ayesha Naeem

An escape sequence in C is used to conveniently format the strings and outputs of a program.

The escape sequence does not appear in the output when written in a character or string literal, rather it is represented through its functionality. The escape sequence consists of a backslash and any other character from the C character set.

Types of escape sequences

Below are the 15 types of escape sequences that C provides:

Escape Sequence Meaning Description
\a Alarm or Beep Generates a beep that alerts the user when the program is executed.
\n New Line Starts a new line in the output/string.
\t Horizonal Tab Adds a horizontal tab in the output/string.
\r Carriage Return Places the cursor at the start of the current line.
\f Form Feed Places the cursor at the start of the next page.
\v Vertical Tab Adds a vertical tab in the output/string.
\\ Backslash Displays a backslash in the output/string.
\' Single Quote Displays a single quote in the output/string.
\" Double Quote Displays a double quote in the output/string.
\nnn Octal Number Represents an octal number.
\xhh Hexadecimal number Represents a hexadecimal number.
\0 Null Adds a 0 character and usually denotes the termination of a string.
\b Backspace Backspaces a single character.
\? Question Mark Displays a question mark.

Examples

The following code demonstrates the use of various C escape sequences such as \n, \t, \?, and \":

#include <stdio.h>


int main() {
 
 printf("---\\n---\n");
 // Example 1
 printf("What are escape sequences in C\nEducative.io");
 printf("\n");
 printf("---\\t---\n");
 //Example 2
 printf("What are escape sequences in C\tEducative.io");
 printf("\n");
 printf("---\\?---\n");
 // Example 3
 printf("What are escape sequences in C \? Educative.io");
 printf("\n");
 printf("---\\\"---\n");
 // Example 4
 printf("What are escape sequences in C \" Educative.io");
 printf("\n");
 printf("---\\\'---\n");
 // Example 5
 printf("What are escape sequences in C \' Educative.io");
 printf("\n");
 printf("---\\xhh---\n");
 // Example 6
 printf("What are escape sequences in C \x3a Educative.io");
 printf("\n");
 printf("---\\nnn---\n");
 // Example 7
 printf("What are escape sequences in C \123 Educative.io");
 printf("\n");
}

Explanation

Example 1

\n will display the string following that character in next line.

Example 2

\t will add a horizontal tab where it is written.

Example 3

\? will display a ? where it is written.

Example 4

\" will display a " where it is written.

Example 5

\' will display a where it is written.

Example 6

\xhh will take the hexadecimal value and convert it to decimal, then it will display the corresponding ASCII character. In this example, x3a is 58 in decimal, and the corresponding ASCII character is :.

Example 7

\nnn will take the octal value and convert it to decimal; then, it will display the corresponding ASCII character. In this example, 123 is 83 in decimal, and the corresponding ASCII character is S.
