新标准C++ 程序设计课后题答案学习资源

《新标准C++程序设计》是一本常用的C++教材，它循序渐进地介绍了C++编程的基础知识和高级特性。每一章的末尾都有一些课后习题，这些习题对于读者巩固所学内容、深入理解编程思路非常有帮助。然而，很多读者在完成这些习题时会遇到困难，甚至找不到答案。本文就是为这些读者提供帮助的。

1. What is inheritance? What is a derived class? What is a base class?

- Inheritance is a mechanism of creating a new class by deriving the properties of an existing class. The new class is called a derived class and the existing class is called a base class.

- A derived class is a class that inherits properties and methods from its base class.

- A base class is a class that is used as a foundation for other classes to inherit from.

2. What is polymorphism?

Polymorphism is the ability of a class to take on multiple forms. It is achieved through inheritance and virtual functions. Polymorphism allows objects of different types to be treated as if they were objects of the same type.

3. What is the importance of templates in C++ programming?

Templates are important in C++ programming because they allow generic programming. Templates allow you to write code that can operate on a variety of data types without being tied to any specific data type.

4. What is a destructor in C++?

A destructor is a special function that is called when an object is destroyed. It is used to release any resources that were acquired by the object during its lifetime, such as memory or file handles.

5. What is the difference between a class and an object?

A class is a blueprint or template for creating objects, while an object is an instance of a class. A class defines a set of properties and methods that an object can have, while an object has specific values for those properties and can call those methods.
