Pointers are functions in C++ which allows varying sizes of arrays.
Option: (a)
Explanation:
- There are some problems that are to be raised when declaring fixed array sizes. They are no expansion and exceeding maximum.
- To resolve this, dynamic allocation array has been constructed. In order to create a variable that will point an array allocated dynamically, we have to declare it as a pointer to the element type.
- A dynamically allocated array can be declared as a pointer. Here we should not use the declaration part of fixed array size.
