Published on : 30th Sep 2021

Escape sequences is used to format output. It is composed of two or more characters starting with \ (Backslash).
Let's us discuss some useful escape sequences in C programming.
\n => New line
\b => Backspace 
\t => Horizontal tab 
\v => Vertical tab
\r => Carriage return (Go to the beginning of the current line) 
\' => Single quote
\" => Double quote 
\\ => Backslash 
\f => Form feed (go the next page or section)
\ddd => Octal number 
\xdd => Hexadecimal number 
\0 => Null value (It's backslash followed by zero.)
Example:
#include <stdio.h>

int main(int argc, char** argv)
{
	char num1[] = "\276";
	char num2[] = "\x38";
	printf("How are you?\nI'm fine.");
	printf("\n");
	printf("Octal number = %s\n", num1);
	printf("Hexadecimal number = %s\n", num2);
	return 0;
}
Output: 
How are you?
I'm fine.
Octal number = ╛
Hexadecimal number = 8
Explanation: 
Here, \n is used to print a new line.
In num1,  \276 is converted to to its equivalent ASCII number, then it is getting printed.
The similar thing is happening for num2.
