Transposing a matrix

Here, we will read a matrix from the user and then transpose the matrix. The transpose of the matrix means, here we replace the rows by columns in the matrix.

Algorithm/Steps

The steps to transpose a matrix in C# are:

• Create a matrix i.e., a two-dimensional array.
• Input the matrix elements.
• To transpose a matrix, just use two loops. Run the outer loop till columns and the inner loop till rows.
• It will print the transpose of a matrix.

C# program to transpose a matrix

The source code to transpose a matrix is given below. The given program is compiled and executed successfully on Microsoft Visual Studio.

```//C# program to transpose a matrix.

using System;

class MatrixDemo
{
public static void Main(string[] args)
{
int i = 0;
int j = 0;

int row = 2;
int col = 2;

int[,] Matrix= new int[row, col];

Console.Write("Enter the elements of matrix: ");
for (i = 0; i < row; i++)
{
for (j = 0; j < col; j++)
{
}
}

Console.WriteLine("\nMatrix: ");
for (i = 0; i < row; i++)
{
for (j = 0; j < col; j++)
{
Console.Write(Matrix[i, j] + "\t");

}
Console.WriteLine();
}

Console.WriteLine("Transpose of matrix : ");
for (i = 0; i < col; i++)
{
for (j = 0; j < row; j++)
{
Console.Write(Matrix[j, i] + "\t");

}
Console.WriteLine();
}
}
}
```

Output

```Enter the elements of matrix: 1
2
3
4

Matrix:
1       2
3       4
Transpose of matrix :
1       3
2       4
Press any key to continue . . .
```

Explanation

In the above program, we created a class MatrixDemo that contains a Main() method. The Main() method is the entry point for the program, Here, we created a 2-D array to represent a matrix with size 2X2. Then we read elements of the matrix form user and then print the transpose of the matrix by replacing rows by columns.
