在C++中，有許多強大的面向對象程序設計特性可以幫助我們更有效地編寫程式。其中一個重要的特性是虚函数，它允許我們在父類中聲明一個函數為虚函數，並在子類中重寫（override）這個函數，從而實現多態性。這意味著在運行時，系統將根據對象的實際類型來調用相應的函數。
另一個關鍵字是运算符重载，它使我們可以對C++中的內建運算符，如+、-、*等進行重載，從而讓其支持我們自定義的數據類型。這樣一來，我們就可以定義運算符對新的類型進行操作，使得我們的程序更具彈性。
在C++中，我們也可以使用常量來定義不可修改的變量，這樣可以確保程序的穩定性和安全性。另外，靜態變量或函數則可以在整個程序中保持其值的持久性，而不會隨著函數的調用而被重置。
總的來說，C++提供了豐富的面向對象程序設計特性，包括虚函數、重寫、運算符重載、常量和靜態變量或函數等，這些特性使得我們可以更靈活地設計和編寫程序。
Keyword: Virtual Function, Override, Operator Overloading, Constant, Static Variable or Function, Title: Object-Oriented Programming Features in C++,
Article: In C++, there are many powerful features of object-oriented programming that can help us write code more efficiently. One important feature is virtual functions, which allow us to declare a function as virtual in the base class and override it in the derived class, achieving polymorphism. This means that at runtime, the system will call the appropriate function based on the actual type of the object.
Another keyword is operator overloading, which enables us to overload built-in operators in C++ such as +, -, *, etc., to support our custom data types. This way, we can define operators to operate on new types, making our program more flexible.
In C++, we can also use constants to define variables that cannot be changed, ensuring the stability and safety of the program. Additionally, static variables or functions can maintain their values throughout the program without being reset with each function call.
Overall, C++ provides rich features of object-oriented programming, including virtual functions, overriding, operator overloading, constants, and static variables or functions, allowing us to design and write programs more flexibly.
