What are some advanced pointer techniques in C?

Advanced pointer techniques in C include pointer arithmetic, function pointers, and pointers to pointers. Would you like to explore any specific technique?

Can you explain pointer arithmetic?

Pointer arithmetic allows you to perform operations on pointers, such as incrementing or decrementing them to navigate through arrays. For example, if you have an integer array, incrementing a pointer to the first element will point it to the second element.

What about function pointers?

Function pointers are pointers that point to the address of a function. They allow you to call functions dynamically and can be used for callback functions or implementing function tables.

How do I use pointers to pointers?

Pointers to pointers are used to store the address of another pointer. This is useful in scenarios like dynamic memory allocation for multi-dimensional arrays or when you need to modify a pointer in a function.
