Answer 6

Pointer variable is a one kind of variable that points another variable. It points another variable by storing address location of that variable. To declare pointer, you need to use * sign followed by meaningful variable name.

Suppose,
int a = 10; // variable declaration
int *p; // pointer declaration
p = &a; // p store the address of a
*p = 10 // *p equals to 10, means *p indirectly access a variable value by storing address location of a.

In C by default array name acts as a pointer to first element of the array. That may be called as internal pointer.
