The idea of analogy learns arrays and pointers, and C + + provides low-level composite types like vectors and iterators-arrays and pointers. Similar to vectors, arrays can hold a set of objects of a certain type, but the difference is that the

The pointer can point to a variable, an array, or a function, which is a pointer to a function whose name is actually the starting address in the program's memory. A pointer to a function can pass an address to a function or it can be returned from
