. It's a pointer variable which can hold the address of another pointer variable. It de-refers twice to point to the data held by the designated pointer variable. Both allocates memory from heap area/dynamic memory.

it is used to access array element
It is used in call by reference method
It is used for dynamic memory allocation
It is used in data Structure like tree graph and linked list etc.

Pointers in C are easy and fun to learn. Some C programming tasks are performed more easily with pointers, and other tasks, such as dynamic memory allocation

A pointer differs in the way that a pointer is a variable that points to another variable. A pointer holds the memory address of that variable. That variable contains a value. Pointers are also called address variables because they contain the addresses of other variables.

Pointers used as Writeable Function Parameters. ... If one has a pointer to the variable instead of the variable itself as the parameter then, even though that pointer gets copied, one can use its value, the memory address, to directly access the memory where the value of the original variable is stored.

1:pointers increase the execution speed
2:a pointers enable us to access a variable that is defined outside the function
3:pointres are more efficient in handling the data tables
4:pointers reduce the length and complexity of a program
5:the use of pointer array to character strings results in savimg of data storage space in
memory

The reason is that pointers are used to bodge into C some vital features which are missing from the original language: arrays, strings, & writeable function parameters. They can also be used to optimize a program to run faster or use less memory that it would otherwise.
