Why Boolean Data Type Occupies One Byte
In C , booleans occupy a byte of memory, despite their binary nature. This is a consequence of hardware limitations rather than any inherent properties of the data type.
The underlying hardware, specifically the CPU, cannot efficiently address and manipulate data smaller than a byte. By requiring booleans to occupy a byte, the CPU simplifies memory management and optimizes performance.
Absence of Smaller Integer Types
Similarly, there are no integer types smaller than 8 bits (one byte) because:
When designing emulators, it is necessary to consider the limitations of the CPU being emulated. By understanding the reasons behind the byte-sized booleans and the absence of smaller integer types, you can accurately model the behavior of the target CPU in your emulated system.
