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:
1. Different Types
BOOL is int type
Bool is Boolean
2. Different Lengths
Bool has only one byte
The BOOL length depends on the actual environment. Generally, it can be regarded as 4

Bool? The data type that can be null can contain three different values: True, false, and null. So bool? Type cannot be used in conditional statements, such as if, for, or while. For example, this Code cannot be compiled and a compiler error cs0266
