In C++, a pointer is a variable that holds the memory address of another object. It "points" to the memory location where another variable or object is stored. By using pointers, you can indirectly access and manipulate the data stored in memory.
Here are some key points to understand about pointers in C++:
Pointers are a powerful feature in C++ that allows for more advanced memory manipulation and dynamic memory management. They enable efficient memory usage and provide flexibility when working with data structures, arrays, and dynamic objects. However, incorrect use of pointers can lead to bugs, such as segmentation faults or memory leaks, so it's crucial to handle them with care and ensure proper memory management.
