Creating array of pointers in C++

An array of pointers is an array of pointer variables. It is also known as pointer arrays. We will discuss how to create a 1D and 2D array of pointers dynamically. The word dynamic signifies that the memory is allocated during the runtime, and it allocates memory in Heap Section. In a Stack, memory is limited but is depending upon which language/OS is used, the average size is 101.

 

Dynamic 1D Array in C++: An array of pointers is a type of array that consists of variables of the pointer type. It means that those variables can point to some other array elements.
