In C/C++ values are represented as binary numbers and not checked for invalid ranges. This means that the signed 8 bit value 127 plus one is -128 because the addition causes an integer overflow.

Signed integer overflows evoke undefined behavior, while unsigned overflows are mathematically defined (they wrap around).
