Knowledge Point 1. Are there bool types in C language?
From http://blog.csdn.net/liuqiqi677/article/details/6703615
I have never noticed that when I recently wrote a DSP Algorithm in C language, I accidentally found that the bool type variables

BOOL is a standard C + + data type
BOOL is a standard C + + data type, and the value is true and false. A single byte, depending on the compiler, if several bool objects are listed together, each may take up a bit.
BOOL is a Microsoft-defined
I. Differences between BOOL and bool are found on the Internet:

BOOL is int type
Bool is Boolean
2. Different Lengths
Bool has only one byte

Normally we would declare the BOOL variable:
class CMyClass { ... BOOL m_bVar1; BOOL m_bVar2; BOOL m_bVar3; BOOL m_bVar4; BOOL m_bVar5; BOOL m_bVar6; BOOL m_bVar7; BOOL m_bVar8; ... };
