For dynamic memory allocation: Pointers are used in the allocation and deallocation of memory while the program is being executed. Call by Reference: The pointers are used to pass the reference of a VARIABLE to another function. Data Structures like a graph, tree, linked list, etc.: The pointers are used to CONSTRUCT a number of data structures like graph, tree, linked list, and so on.
