Char-Data Type

Character Data Type

C stores character type internally as an integer. Each character has 8 bits so we can have 256 different characters values (0-255).

Character set is used to map between an integer value and a character. The most common character set is ASCII.

Let take a look at example of using a variable which hold character 'A'.

#include<stdio.h>

	void main()
	{

	char ch = 'A';
	printf("%c\n",ch);

	ch = 65;// using integer representation
	printf("%c\n",ch);

	ch = '\x41';   // using hexadecimal representation
	printf("%c\n",ch);

	ch = '\101';   // using octal representation
	printf("%c\n",ch);

}

Here is the output

A
