As a reminder, the name of a variable (or function, type, or other kind of item) is called an identifier. C++ gives you a lot of flexibility to name identifiers as you wish.

A variable whose value ….A return statement (with no return value) can be used in a void function -- such a statement will cause the function to return to the caller at the point where the return statement is executed. This is the same thing that happens at the end of the function anyway.

In an inheritance (is-a) relationship, the class being inherited from is called the parent class, base class, or superclass, and the class doing the inheriting is called the child class, derived class, or subclass. In the above diagram, Fruit is the parent, and both Apple and Banana are children.A local variable’s scope begins at the point of variable definition, and stops at the end of the set of curly braces in which it is defined (or for function parameters, at the end of the function). This ensures variables can not be used before the point of definition (even if the compiler opts to create them before then).

Deleting a single variable. When we are done with a dynamically allocated variable, we need to explicitly tell C++ to free the memory for reuse. For single variables, this is done via the scalar (non-array) form of the delete operator: delete ptr; ptr = nullptr;Jul 6, 2012 · 如果你已经学过一门编程语言,并且打算成为专业C++开发者,从《C++ Primer 第四版》入手不会让你走弯路。. 值得特别说明的是,学习本书不需要事先具备C语言知识。. 相反,这本书教你编写真正的C++程序,而不是披着C++ 外衣的C程序。. 《C++ Primer 第四版》的定位 ...

In C++, any name that is not defined inside a class, function, or a namespace is considered to be part of an implicitly-defined namespace called the global namespace (sometimes also called the global scope ).
