pointers function type * function name ([formal parameter type declaration table]) {function Body}Pointers to functions A general definition of a pointer to a function: Data type (* pointer variable name) (parameter type list) Call Mode: (* pointer variable name) (actual parameter list) Int (*functionpointer) (int a); Functionpointer = func; Func i

Pointers are really easy to understand, and others are not as magical and difficult as everyone imagined.first, the meaning of the pointer: The pointer is actually a variable, it does not hold the data, but the data in memory address. Of course the pointer can also hold the address of the function (method), which will be mentioned later. The key for declaring a
