'''signed char''' is the smallest signed integer type in C++, it often gets typedef-ed as "byte" (alternatively people use [[unsigned char]] for that reason) because it uses one byte of memory (depending upon what architecture defines it as, but no less than 8 bits). The range of values that can definitely be stored in this type is -128 – 127.

==Relationship with char==
'''signed char''' uses exact same amount of memory as '''char''', the main difference happens during the output; '''char''' gets interpreted as the code of [[ASCII]] character, while '''signed char''' is interpreted as [[two's complement]] signed integer.

==Other C++ datatypes of the same size==
* [[char (C++)|char]]
* [[unsigned char]]

==Other C++ data types storing signed integers==
* [[signed short int|short]] no less than 16 bits, no less than char
* [[signed int|int]] no less than 16 bits, no less than short
* [[signed long int|long]] no less than 32 bits, no less than int
* [[signed long long int|long long]] no less than 64 bits, no less than long
