C++ Basics: Introduction to Pointers

Pointers play a major role in dealing with computer memory. It becomes quite important to learn about pointers when you are working with low-level stuff like dynamic memory handling. This concept is much more popular in the C language and not verrry important in C++. C++ handles all the dirty work for us leaving nothing to worry about. Anyways it is still important to understand this stuff if you are (let's say) planning to work in a huge company with high-performance products. Thank me later.

A pointer is a variable that stores the address of another variable. Unlike other variables that hold values of a certain type, pointer holds the address of a variable. For example, an integer variable holds (or you can say stores) an integer value, however an integer pointer holds the address of a integer variable.
