Pointers are variables that store memory addresses of other variables in programming languages.
Pointers allow direct access and manipulation of memory locations.
They are commonly used in programming languages like C and C++.
Pointers can be used to pass variables by reference, allowing modifications to the original value.
They can also be used to dynamically allocate memory.
Example: int* ptr; // declares a pointer to an
