void pointer
The concept of void pointer: it is a typeless pointer that can point to any type of data, it can be called a generic pointer or a generic pointer
Some things to note about the void pointer:
1. In C language, you can use void pointer instead of other types of pointers at any time, and void pointers can point to variables of any data type
2. If you use the void pointer to obtain the variable it points to, you need to convert the strong type of the void pointer to a data type pointer that matches the same variable type
3. Any type of pointer can be directly assigned to the void pointer without strong type conversion
