Memory representation of char data type in C

Char data types may be signed or unsigned. Size
of char data type is 8 bit. Both signed and unsigned have different memory
representation.


Memory representation of unsigned
char: In
unsigned char all 8 bit is used as data bit


Memory representation of unsigned char a= 7;

Binary equivalent of 7
is:  111

For 8 bit we will add 5
zero in the left side i.e. 00000111. In
the memory:
