Pointers in C
Pointer means variable that store memory address
In this video the explanation of pointer has been described.
For using pointer the declaration, Initialization and dereferencing should be
used. How declaration, Initialization and dereferencing is done is very well
explained in this video with the help of example.
Pointers are one of the core components of the C Programming language
which can be used to store the memory address of other variables,
functions or even other pointers. The use of pointers allows low-level
memory access, dynamic memory allocation and many other functionality
in C. Pointer is a derived data type that can store the address of other C
variable or a memory location. We can access and manipulate the data
stored in that memory location using pointers. The size of the pointer
depends upon the architecture of the computer.
The use of the pointer can be divided into three steps :
1. Pointer Declaration
2. Pointer Initialization
3. Dereferencing
