CS201 Assignment 2 Solution Spring 2021


CS201 Assignment 2 Spring 2021 solution idea:

 

CODE:

#include <iostream>

#include <conio.h>

using namespace std;

int ShowMatrix()

{

                int row1=2;

                int column1=2;

                 int matrix[2][2] = { {7, 15} , {13, 5}  };

   cout<<"The matrix is:"<<endl;

   for(int i=0; i<row1; ++i) {

      for(int j=0; j<column1; ++j)

      cout<<matrix[i][j]<<" ";

      cout<<endl;

   }

}

   int showTranspose ( )

{

   int transpose[2][2], row=2, column=2, i, j;

   int matrix[2][2] = { {7, 15} , {13, 5}   };

  

   cout<<endl;

   for(i=0; i<row; ++i)

   for(j=0; j<column; ++j) {

      transpose[j][i] = matrix[i][j];

   }

   cout<<"Transpose of matrix:"<<endl;

   for(i=0; i<column; ++i) {

      for(j=0; j<row; ++j)

      cout<<transpose[i][j]<<" ";

      cout<<endl;

   }

}




int           calculateDeterminant()

{


                int  determMatrix[2][2],determinant;

                int matrix[2][2] = { {7, -15} , {13, 5}  };



                determinant = ((matrix[0][0] * matrix[1][1]) -

                                                                                (matrix[0][1] * matrix[1][0]));



                cout << "\nThe Determinant of 2 * 2 Matrix = " << determinant;              

}




int showAdjoint()

{

                  int ch,A2[2][2] = {{7, -15} , {13, 5}},AD2[2][2],C2[2][2];



        C2[0][0]=A2[1][1]; C2[0][1]=-A2[1][0]; C2[1][0]=-A2[0][1]; C2[1][1]=A2[0][0];



        AD2[0][0]=C2[0][0]; AD2[0][1]=C2[1][0]; AD2[1][0]=C2[0][1]; AD2[1][1]=C2[1][1];

        cout<<"\n\nAdjoint of A is :- \n\n";

        cout<<"|\t"<<AD2[0][0]<<"\t"<<AD2[0][1]<<"\t|\n|\t"<<AD2[1][0]<<"\t"<<AD2[1][1]<<"\t|\n";



}



int main()

{

                int choice = 0;

                cout<<"Enter your choice "<<endl;

                cout<<"Press 1 to display the matrix and its transpose"<<endl;

                                cout<<  "Press 2 to find adjoint and determinant of the matrix"<<endl;

                                cout<<"Press any other key to exit.";

                                cin>>choice;



  if (choice ==1)


                {

             
                ShowMatrix();

    showTranspose ( );

                }

    else if (choice == 2)

    {

        
    showAdjoint();            

                calculateDeterminant();

                }

                else

               

                system("pause");

}
