Pointer Mastery

Pointers are a derived data type in C that contain memory addresses as their values. They are used to store the address of another variable, allowing for direct access to the memory location. Pointers can be used to access and manipulate data stored in the memory.

The advantages of using pointers in C programming include: (i) Simplifying programs and reducing their length, and (ii) Helping in the allocation and deallocation of memory during program execution.

Pointers must be declared before use to store the address of a variable. They are declared using the asterisk () symbol followed by the data type. Pointers are used to access and manipulate data stored in memory by dereferencing the pointer using the asterisk () operator.
