A pointer a pointing to the memory address associated with a variable b, i.e., a contains the memory address 1008 of the variable b. In this diagram, the computing architecture uses the same address space and data primitive for both pointers and non-pointers; this need not be the case. In computer science, a pointer is an object in many programming languages that stores a memory address. This ...
Pointers allow us to change and access the system memory directly. Pointer improves the performance for repetitive processes. Languages such as C and C++ use pointers a lot. However, other languages can also have pointers, though they may not be the same.
Guide to Pointers in Data Structure. Here we discuss why do we need pointers in data structure along with its working and C program on pointers.
