C++ program to transpose matrix.

C++ program to transpose given 3X3 matrix.

#include<iostream>

using namespace std;

int main()

{

  int arr[3][3], arrTrans[3][3];

  int i,j;

 

//Logic for reading matrix from user...

  cout << "Enter 3 x 3 matrix:\n\n";

  for(i=0;i<3;i++)

   for(j=0;j<3;j++)

    {

     cout << "Enter element arr["<< i << "]["<< j <<"]:";

      cin >> arr[i][j];

    }  

  cout << "\nThe Original matrix is: \n";

  for(i=0;i<3;i++)

  {

  for(j=0;j<3;j++)

     cout << "\t" << arr[i][j];

  cout << endl;

  }

  cout << endl;

//Logic for transposing matrix...

  for(i=0;i<3;i++) {

  for(j=0;j<3;j++)

     arrTrans[j][i] = arr[i][j];

  }

 

//Logic for printing Transposed matrix...

  printf("The Transpose of the matrix is: \n");

  for(i=0;i<3;i++) {

  for(j=0;j<3;j++)

     cout << "\t" << arrTrans[i][j];

  cout << endl;

  }

  return 0;

}

Output of program

Enter 3 x 3 matrix:

Enter element arr[0][0]:1

Enter element arr[0][1]:2

Enter element arr[0][2]:3

Enter element arr[1][0]:4

Enter element arr[1][1]:5

Enter element arr[1][2]:6

Enter element arr[2][0]:7

Enter element arr[2][1]:8

Enter element arr[2][2]:9

The Original matrix is:

        1       2       3

        4       5       6

        7       8       9

The Transpose of the matrix is:

        1       4       7

        2       5       8

        3       6       9
