Explanation of Solution
Difference between object and class:
The following table shows the difference between “object” and “class”.
| Object | Class |
| An object is an instance of a class. | A class is a category of objects. |
| An object represents an entity in the real world that can be distinctly identified. | A class uses variables to define data fields, and functions to define behaviors of the class. |
|
Object is followed by the class name. | Class name is represented with the keyword “class”. |
|
Syntax for creating an object: Classname objectname; Sample code: Circle r1; |
Syntax for defining a class: class classname { // Body of the class }; Sample code: //Declare the class class circle { Private: double radius; }; |

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()).
