Expert Solution & Answer
Chapter 1, Problem 15E
Explanation of Solution
Declaration “derivedClass” follows “genClass”:
- Declaration of “derivedClass” class follows “genClass”.
- The “genClass” would act as base class and “derivedClass” acts as subclass.
- A base class is declared so that its member data instances could be shared with any of other inclusions of same base in further derived classes.
- The technique used is termed as virtual inheritance.
- The functions in base class could be used by derived classes.
Refer question 15 from chapter 1 for given declarations.
Member function invocation:
- The function “process1()” in “derived Class” contains integer parameters, the function declaration is hidden in “genClass”...

Object-Oriented Programming
Create a Java program that has the following:
Inheritance - Create a superclass and one or more subclasses that inherit properties and methods from the superclass.
Polymorphism - Show polymorphism by using method overriding and method overloading.
Provide an example of runtime polymorphism by creating objects of the subclasses and calling overridden methods.
Encapsulation - Demonstrate the concept of encapsulation by applying access modifiers (private, protected, public) appropriately in your program.
Abstraction - Utilize abstract classes and methods in your program to illustrate abstraction.
Show examples of the following words: super, this, static, final

Question 9
Which XXX will avoid a memory leak?
class MyClass {
public:
MyClass();
int value;
private: int* ptr;
};
MyClass::MyClass () {
ptr = new int;
*ptr = 0;
delete ptr;
}
int main() {
int value = 100;
int *ptr1= new int;
//XXX
ptr1 = &value;
O delete value
O delete MyClass
O delete ptr1
O delete ptr
Consider the following class code segment:
class aNewClass {
public: …….
private:
string name;
int *q;
int length;
};
// constructor
aNewClass::aNewClass() {
q = new int[10]; // dynamic data
….
}
Name at least ONE thing you should add/code for the dynamic data in this class. (HINT: Look at the member variables).
