c unsigned char size
How many bits is an unsigned char in C?
unsigned char can hold values between 0 and 255. signed char can hold values between -127 and 127.
What is the size of char in C?
In practice, char is usually 8 bits in size and short is usually 16 bits in size (as are their unsigned counterparts).
What is the size of signed char?
The smallest group of bits the language allows use to work with is the unsigned char , which is a group of 8 bits.
