A class in C++ is a user-defined type or data structure declared with any of the keywords class, struct or union (the first two are collectively referred to as non-union classes) that has data and functions (also called member variables and member functions) as its members whose access is governed by the three access specifiers private, protected or public.
C++ uses the three modifiers called public, protected, and private. [3] C# has the modifiers public, protected,internal, private, protected internal, private protected, and file. [4] Java has public, package, protected, and private; package is the default, used if no other access modifier keyword is specified. The meaning of these modifiers may ...
The choice of a variable name should be mnemonic — that is, designed to indicate to the casual observer the intent of its use. One-character variable names should be avoided except for temporary "throwaway" variables. Common names for temporary variables are i, j, k, m, and n for integers; c, d, and e for characters. int i;
In C++, the only difference between a struct and a class is the default access level, which is private for classes and public for structs. [3] To illustrate the benefit: consider a public variable which can be accessed from any part of a program.
In computer programming, a global variable is a variable with global scope, meaning that it is visible (hence accessible) throughout the program, unless shadowed.The set of all global variables is known as the global environment or global state.
