True.
a method declared final can not be overridden, and a class declared as final can not be extended by its sub class.
There are two ways to reuse a class in C++. Composition and inheritance. With composition, any class data member can be an instance of an existing class. With inheritance, we can derive a new class from an existing class. Either way, we create a new class of object with all the properties of the existing class which can be extended and/or replaced with properties of our own.
Abstract classes are to be extended until to a concrete class.Can have both abstract & non abstract methods.An Abstract class can not be instantiated.A non abstract class can be extended to an abstract class.If At least one abstract method present in a class then that class must be abstract.abstract & final modifiers can never be together.abstract classes can have both abstract methods & non abstract methods.
When a derived class inherits from a base class, the base class functionality is being extended.
A superclass, also referred to as a parent class, is a class what which other classes are derived from. These derived classes are known as either subclasses or child classes.
classes can be extended and interfaces can be implemented.

In one class, there are 4 boys. With 20 classes in the school, the total number of boys is calculated by multiplying the number of boys per class by the number of classes: 4 boys/class × 20 classes = 80 boys. Therefore, there are a total of 80 boys in the whole school.

Sturges's Rule can be used to determine the number of class intervals for a frequency distribution by using the formula ( k = 1 + 3.322 \log(n) ), where ( n ) is the number of data points. While it helps in establishing the number of classes, it does not directly determine the class interval size. Instead, once the number of classes is established, the range of the data can be divided by the number of classes to find the class interval. Thus, Sturges's Rule is a useful guideline for class interval selection in data analysis.

The plural of "class" is "classes."
class is before classes.
