char data type in c

Character data type:

• ‘char’ is the keyword used to declare character data type in C program.
• Using char data type, we can store alphabets, digits and special symbols.
• We must specify the character using single quotes.
• “%c” is the format specifier to display the symbols.

#include <stdio.h>
int main()
{
	char v1 = 'a';
	char v2 = '5';
	char v3 = '$';
   	printf("v1 value is : %c \n", v1);
	printf("v2 value is : %c \n", v2);
	printf("v3 value is : %c \n", v3);
	return 0;
}

Output:
v1 value is : a
v2 value is : 5
v3 value is : $

Memory representation:

• In computer, memory always represents in bytes.
• Byte equals to 8 bits.
• Binary information will store as bits into memory
• The minimum and maximum values we can store into byte as follows:

How computer stores symbols and alphabets into memory?

• Every symbol or alphabet or digit will be automatically converted into binary value using character system.
