Explanation of common symbols in C Language

1. # include <> Format: reference the standard library header file. The Compiler starts searching from the standard library directory;

2. # include "" Format: reference non-standard library header files. The Compiler starts searching from the user's working directory;

3. In C, the "^" symbol is a bitwise operation, XOR, or;

4. in C language, symbols & yes & representation and operations, for example, a & B indicate that a and B perform and operate;

5. What does the symbol mean in C language? For example, c = a-> B

A is a pointer to a struct or consortium.-> indicates that a Member is called.

6. in C language, the symbol "! = "And" = "mean? For example,! = B, a = 0

! = Indicates that the logic is not equal to the number and = indicates whether the result is equal:

For example:

Int a = 3, B = 4

A! = B, the value of a is not equal to the value of B, so! = B is correct

A = 0 is used to determine whether a is equal to 0. Obviously, it is not equal to 0, so it is false.
