Chapter 10, Problem 24PE

Create a Matrix class and implement the following member functions: The constructors and the destructor getSize() which returns the size of the matrix; setValue( int position, int value) which sets the value in the matrix at given position; getValue (int position) which returns the current value at given position; an add method which adds two matrices together; A= ● ● a subtract method which subtract two matrices together; a multiply methods which multiplies two matrices together, if possible; an overlap function which overlaps two matrices together. The augment function takes two matrices A and B of size mlxnl and m2xn2, respectively, and produce a new matrix C of size mLxnL, where mL (resp. nL) is the largest between m1 and m2 (resp. nl and n2). The values of C will either come from the original matrices by overlapping matrix B over matrix A. Wherever a value is not available it initialized to default value 0. For example: If you overlap two matrices A of size 4x2 and B of size 3x5,…

array of Payroll ObjectsDesign a PayRoll class that has data members for an employee’shourly pay rate and number of hours worked. Write a program withan array of seven PayRoll objects. The program should read thenumber of hours each employee worked and their hourly pay ratefrom a file and call class functions to store this information in theappropriate objects. It should then call a class function, once foreach object, to return the employee’s gross pay, so this informationcan be displayed.

: A designer in 3D graphics company wants to design a matrix as a two-dimensional array. The size of 2D array could be the last two digit of arid number. Initially he creates a class matrix that provides the member function to check that no array index is out of bounds. Make the member data in the matrix class a 10-by-10 array. A constructor should allow the programmer to specify the actual dimensions of the matrix (provided they’re less than 10 by 10). The member functions that access data in the matrix will now need two index numbers: one for each dimension of the array. Here’s what a fragment of a main() program that operates on such a class might look like: If my Arid Number is  20-Arid-254 then:    // in case of zero consider next digit  matrix m1(5, 4); // define a matrix object  int temp = 12345; // define an int value m1.put(3, 4, temp); // insert value of temp into matrix at 3,4 temp = m1.get(3, 4); // obtain value from matrix at 3,4
