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.
| 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 | value |
|---|---|---|---|---|---|---|---|---|
| 1 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | -128 |
| 0 | 1 | 1 | 1 | 1 | 1 | 1 | 1 | 127 |
| 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 |
