Detailed Description

Structure of a character attribute consists of 4 bit fore- and 3 bit background color, and a single blink bit.

Bit fields can notably simplify the access and code readability.

Note: Type punning is indeed undefined behavior in C++. However, gcc explicitly allows this construct as a language extension. Some compilers (other than gcc might allow this feature only by disabling strict aliasing (-fno-strict-aliasing). In StuBS we use this feature extensively due to the improved code readability.
