The pointer operation refers to the application of certain operators of the pointer. He is a separate theme derived from ordinary computments, why he must follow a specific constraint in order to ensure proper operation.
For example, for calculations, the result of its operation P is determined based on the type P itself, rather than pointing to P 1, and the compiler will automatically point the result to the lower value of the next value in the P array, that is, the actual address is in P Add a single element length.
