c unsigned char vs char

Usually char is signed, but it depends on the system and on the language.
In C char is usually signed 8 bit, in Java char is unsigned 16 bit I think.

Why use unsigned char?

Use unsigned char if you want small integers, in the range 0 to 255.
Use signed char if you want small signed integers, range -128 to 127 guaranteed.
If the plain one is signed or not is implementation dependent.
I'd suggest using the fixed length integer types in inttypes._{8 mai 2019}

What is the difference between unsigned char and char in C?

(Signed) chars store a single byte of memory.
The value stored by this byte can range from -128 to 127.
Unsigned chars also store one byte, but since it is unsigned, the possible range of value is 0 to 255 instead._{4 jan. 2021}

Is char the same as signed char?

A char is a distinct type from signed char and unsigned char , and the three types are not compatible.
