Access Modifiers: To set the access levels of variables,methods (members of a class) we use
Access Modifiers.The different types of access specifiers available are:
1. Public
2. Private
3. Protected
Public: When we declare a variable, method as public, it means that we can access those from
outside the class but within a program . When we inherit a class all public members of the class
will be accessible by the derived class.
Usage: Prefix the variable or method definition by the keyword public.
Example: public:
int x;
public:
void print();
Private: When we declare a variable, method as private, it means that we can access them only
within the class. Private variables of a class can be accessed only through getter and setter
methods which are public. By default the members of a class are private, if we do not specify any
access modifier it is considered to be private. This is concept used to achieve encapsulation.
Usage: Prefix the variable or method definition by the keyword private
Example: private:
int x;
public:
void setX();
Protected: When we declare a class, variable, method.,etc as public, it means that we can access
them within the class and the class with inherits it i.e,protected members can be accessed by the
derived class or child class also.
Usage: Prefix the variable or method definition by the keyword protected
Example: protected:
int x;
1(c): class Rectangle: public Shape{
protected:
string _type;
public:
bool isSquare() {
if(width==height) return true;
return false;
}
double area() {
return width*height;
}
};
How are the Rectangle class and Shape class related?
Answer: D. The Rectangle class inherits the Shape class.
