A matrix is given in source data. You have to write user defined functions and create a menu in C++ keeping in mind the following requirements:

1. Press 1 to display the matrix and its transpose.
(Hint: Transpose of a matrix can be achieved by changing its rows into columns or columns into rows.)

2. Press 2 to find adjoint and determinant of the matrix.
(Hint: To find adjoint of a matrix, we change the places of its diagonal elements and the signs of non-diagonal
elements; To find determinant of matrix, we subtract the product of non-diagonal elements from the product
of diagonal elements.)

3. Press any other key to exit.

Source data:
(Use two dimensional array to store following matrix)

Instructions to write C+program:

Write functions to display the matrix; find transpose, adjoint and determinant of the matrix. Following function names should be used for consistency

Sample Output
1) When 1 is pressed
2) When 2 is pressed
3) When any other key is pressed

To display matrix To show transpose To show adjoint To find determinant showMatrix(); showTranspose(); showAdjoint(); calculateDeterminant();
