C++ Variables and Types - Online Tutorials Library C++ also allows to define various other types of variables, which we will cover in subsequent chapters like Enumeration, Pointer, Array, Reference, Data structures, and Classes Following section will cover how to define, declare and use various types of variables Variable Definition in C++ A variable definition tells the compiler where and how much storage to create for the variable A
How To Write C++ Variables - Nick McCullum The characteristics and scope of C++ variables is also tremendously important In this article, I explained C++ variables (and their characteristics, scope, and attributes) in detail
