Concept explainers

Concept of memory addresses in pointers

The concept of pointers in high-level languages was introduced in C programming. Pointers are simply the variables that are used to store memory addresses of another variable. These special variables are generally used in the languages such as C Programming and C++ Programming, where it allows the programmer to work more deeply with memory and its addresses.
