As you want to get the details of Pointer in C Language so here is the information of the same for you:

A pointer is a variable whose value is the address of another variable, i.e., direct address of the memory location.

Like any variable or constant, you must declare a pointer before you can use it to store any variable address.

The general form of a pointer variable declaration is:

type *var-name;

Here, type is the pointer's base type; it must be a valid C data type and var-name is the name of the pointer variable.

The asterisk * you used to declare a pointer is the same asterisk that you use for multiplication.

However, in this statement the asterisk is being used to designate a variable as a pointer.
