How Many Ways Are There to Pass a Pointer to a Function

The four ways to pass a pointer to a function in C++ | surfdev.

How do you pass a pointer to a function?

Pass-by-pointer means to pass a pointer argument in the calling function to the corresponding formal parameter of the called function. The called function can modify the value of the variable to which the pointer argument points. When you use pass-by-pointer, a copy of the pointer is passed to the function.

Can we pass pointer to a function as parameter?

You cannot pass function to another function as parameter. But, you can pass function reference to another function using function pointers. Using function pointer you can store reference of a function and can pass it to another function as normal pointer variable.
