C模拟CPP的方法重写(override)和多态 1. 所谓override,就是子类中重新实现了父类中的某一方法(子类和父类的同一个方法的方法体不同) 2. 所谓多态,最显著的一个特点就是父类指针指向不同的子类对象时,运行同一个方法会有不同的行为 3. C语言模拟继承时,父类对象必须是子类对象的第一个成员 4. 理解了C的...

In the C programming language until C23, at least one named parameter must appear before the ellipsis parameter, soR printz(...);is not valid until C23. In C++, this form is allowed even though the arguments passed to such function are not accessible, and is commonly used as the fallbac...
