Answer 1

A pointer is a variable which is use to store the address of another variable.

e.g,

int *var1,var2;

var1 = &var2;

Pointers are used program to access the memory and manipulate the address.

in the example you can change the value of var2 since manipulation is done direcly on the memory of var2.

In computer programming, a dereference operator, also known as an indirection operator, operates on a pointer variable, and returns the location-value, or l-value that it points to in memory. In the C programming language, the deference operator is denoted with an asterisk (*).

In linkedlist you can create infinite list(or node) using pointer, because pointer help to dynamically allocate memory at run time.
