Question
Chapter 4, Problem 6E
Program Plan Intro
Abstract Base Class:
- At least a single pure virtual function is present in an Abstract class. For sub classes interface is provided by Abstract class.
- The instantiation of Abstract class is not possible whereas refrences and pointers could be created.
- Abstract class contains a pure virtual function along with normal functions and variables
- The purpose of Abstract class is to for up cast. So that its interface could be used by derived class.
- The implementation of all of pure virtual functions is necessary for all classes that inherit an Abstract class. Otherwise they would also become Abstract.

The main() method asks the user to provide the dimension n for a square matrix. A square matrix has an equal number of rows and columns. b. The main() method receives the value of n and calls the matrixSetUp() method that creates a square matrix of size n and populates it randomly with integers between 1 and 9. c. The main method then calls another method named printMatrix() to display the matrix in a matrix format. d. The main method also calls a method named findSumAndAverage() which: • Receives the generated matrix as input. • Calculates the sum of all elements in the matrix. • Calculates the average value of the elements in the matrix. • Stores these values (sum and average) in a single-dimensional array and returns this array • e. The main method prints the sum and average based on the result returned from findSumAndAverage()). Enter the dimension n for the square…arrow_forward
