Program for matrix multiplication

Answer 1

The following C# program will take two matrices of 2*2 order in its input and then print the product of them.

using System;

using System.Collections.Generic;

using System.Text;

namespace matrix_muliplication

{

class Program

{

static void Main(string[] args)

{

int i,j,k,l;

int[,] matrix=new int[2,2];

int[,] matri=new int [2,2];

int[,] matr=new int [2,2];

Console.WriteLine("Enter 1st 2*2 matrix: \n");

for (i=0;i<2;++i)

{

Console.WriteLine("Enter "+ (i+1) +"# row: ");

for (j=0;j<2;++j)

{

matrix[i,j]=Int32.Parse( Console.ReadLine());

}

}

Console.WriteLine("\n");

Console.WriteLine("Enter 2nd 2*2 matrix: \n");

for (i=0;i<2;++i)

{

Console.WriteLine("Enter "+(i+1)+" # row: ");

for (j=0;j<2;++j)

matri[i,j]=Int32.Parse(Console.ReadLine());

}

Console.WriteLine();

Console.WriteLine("Matrix muliplication");

for (j=0;j<2;++j)

{

for (i=0;i<2;++i)

{

for (l = 0; l < 2; ++l)

{

matr[i, j] = matr[i, j] + (matrix[i, l]) * (matri[l, j]);

}

}

}

for (i = 0; i < 2; i++)

{

for (j = 0; j < 2; j++)

{

Console.Write(matr[i, j] + "\t");

}

Console.WriteLine();

}

}

}

}
