A pointer is a programming concept used in computer science and software development.
It is a variable that stores the memory address of another variable or object. Pointers are essential for dynamic memory allocation and data manipulation in languages like C and C++.
They enable efficient memory management and access to data structures by referencing the location of data in a computer’s memory.
Pointers are a powerful tool but require careful use to avoid memory-related errors such as segmentation faults or memory leaks in programs.
