C++ Program to Find Transpose of a Matrix.

C++ Program to Find Transpose of a Matrix.

#include <iostream.h>

    cout << "Enter rows and columns of matrix: ";

    cin >> r >> c;

    // Storing element of matrix entered by user in array a[][].

    cout << endl << "Enter elements of matrix: " << endl;

    for(i = 0; i < r; ++i)

    for(j = 0; j < c; ++j)

    {

        cout << "Enter elements a" << i + 1 << j + 1 << ": ";

        cin >> a[i][j];

    }

    // Displaying the matrix a[][]

    cout << endl << "Entered Matrix: " << endl;

    for(i = 0; i < r; ++i)

        for(j = 0; j < c; ++j)

        {

            cout << " " << a[i][j];

            if(j == c - 1)

                cout << endl << endl;

        }

    // Finding transpose of matrix a[][] and storing it in array trans[][].

    for(i = 0; i < r; ++i)

Output:-

Enter rows and column of matrix: 2

3

Enter elements of matrix:

Enter elements a11: 1

Enter elements a12: 2

Enter elements a13: 9

Enter elements a21: 0

Enter elements a22: 4

Enter elements a23: 7

Entered Matrix:

1  2  9

0  4  7

Transpose of Matrix:

1  0

2  4

9  7
