C# Sharp Exercises: Accept two matrices and check whether they are equal
C# Sharp Array: Exercise-30 with Solution
Write a program in C# Sharp to accept two matrices and check whether they are equal.
Sample Solution:-
C# Sharp Code:
using System;
public class Exercise30
{
public static void Main()
{
int[,] arr1 = new int[50,50];
int[,] brr1 = new int[50,50];
int i, j, r1, c1, r2, c2, flag =1;
Console.Write("\n\nAccept two matrices and check whether they are equal :\n ");
Console.Write("-----------------------------------------------------------\n");
Console.Write("Input the number of rows in the 1st matrix : ");
r1 = Convert.ToInt32(Console.ReadLine());
Console.Write("Input the number of columns in the 1st matrix : ");
c1 = Convert.ToInt32(Console.ReadLine());
Console.Write("Input the number of rows in the 2nd matrix : ");
r2 = Convert.ToInt32(Console.ReadLine());
Console.Write("Input the number of columns in the 2nd matrix : ");
c2 = Convert.ToInt32(Console.ReadLine());
Console.Write("Input elements in the first matrix :\n");
for(i=0;i<r1;i++)
{
for(j=0;j<c1;j++)
{
Console.Write("element - [{0}],[{1}] : ",i,j);
arr1[i,j] = Convert.ToInt32(Console.ReadLine());
}
}
Console.Write("Input elements in the second matrix :\n");
for(i=0;i<r2;i++)
{
for(j=0;j<c2;j++)
{
Console.Write("element - [{0}],[{1}] : ",i,j);
brr1[i,j] = Convert.ToInt32(Console.ReadLine());
}
}
Console.Write("The first matrix is :\n");
for(i=0;i<r1;i++)
{
for(j=0;j<c1 ;j++)
Console.Write("{0} ",arr1[i,j]);
Console.Write("\n");
}
Console.Write("The second matrix is :\n");
for(i=0;i<r2;i++)
{
for(j=0;j<c2 ;j++)
Console.Write("{0} ",brr1[i,j]);
Console.Write("\n");
}
/* Comparing two matrices for equality */
if(r1 != r2 && c1 != c2)
{
Console.Write("The Matrices Cannot be compared :\n");
}
else
{
Console.Write("The Matrices can be compared : \n");
for(i=0; i<r1; i++)
{
for(j=0; j<c2; j++)
{
if(arr1[i,j] != brr1[i,j])
{
flag = 0;
break;
}
}
}
if(flag == 1 )
Console.Write("Two matrices are equal.\n\n");
else
Console.Write("But,two matrices are not equal\n\n");
}
}
}
Sample Output:
Accept two matrices and check whether they are equal : ----------------------------------------------------------- Input the number of rows in the 1st matrix : 2 Input the number of columns in the 1st matrix : 2 Input the number of rows in the 2nd matrix : 2 Input the number of columns in the 2nd matrix : 2 Input elements in the first matrix : element - [0],[0] : 1 element - [0],[1] : 2 element - [1],[0] : 3 element - [1],[1] : 4 Input elements in the second matrix : element - [0],[0] : 5 element - [0],[1] : 6 element - [1],[0] : 7 element - [1],[1] : 8 The first matrix is : 1 2 3 4 The second matrix is : 5 6 7 8 The Matrices can be compared : But,two matrices are not equal
