Could you please suggest me some good books to master pointers?
Pointers are explicitly-typed memory addresses. A variable, function parameter, method parameter, return type, structure field, or class member that you declare as a pointer contains the memory address of a pointee (the object that the memory address refers to).
You can write memory addresses to pointer variables and read memory addresses from pointer variables. You can dereference pointer variables to get at the pointee and you can take address of an object to get a pointer, including pointer variables themselves (a pointer to a pointer, or double-pointer).
You may decrement pointer variables and you may increment pointer variables, which decrements and increments the stored memory address by the pointee's size. 

C's Arrays and pointers are similar, but cannot be used interchangeably.

C++ has rules for up-casting and down-casting pointers in an object hierarchy.

This should get you started.
