C#: Subtraction of two Matrices
Write a C# Sharp program for the subtraction of two matrixes.
Sample Solution:-
C# Sharp Code:
using System;
public class Exercise20
{
public static void Main()
{
int i, j, n; // Declare variables for loop control and matrix size
int[,] arr1 = new int[50, 50]; // Declare the first matrix
int[,] brr1 = new int[50, 50]; // Declare the second matrix
int[,] crr1 = new int[50, 50]; // Declare the resultant matrix for subtraction
// Display a message prompting the user to input the size of the square matrix (less than 5)
Console.Write("\n\nSubtraction of two Matrices :\n");
Console.Write("------------------------------\n");
Console.Write("Input the size of the square matrix (less than 5): ");
n = Convert.ToInt32(Console.ReadLine());
/* Input elements into the first matrix */
Console.Write("Input elements in the first matrix :\n");
for (i = 0; i < n; i++)
{
for (j = 0; j < n; j++)
{
Console.Write("element - [{0},{1}] : ", i, j);
arr1[i, j] = Convert.ToInt32(Console.ReadLine()); // Store user input in the first matrix
}
}
/* Input elements into the second matrix */
Console.Write("Input elements in the second matrix :\n");
for (i = 0; i < n; i++)
{
for (j = 0; j < n; j++)
{
Console.Write("element - [{0},{1}] : ", i, j);
brr1[i, j] = Convert.ToInt32(Console.ReadLine()); // Store user input in the second matrix
}
}
// Display the first matrix
Console.Write("\nThe First matrix is :\n");
for (i = 0; i < n; i++)
{
Console.Write("\n");
for (j = 0; j < n; j++)
Console.Write("{0}\t", arr1[i, j]); // Print elements of the first matrix
}
// Display the second matrix
Console.Write("\nThe Second matrix is :\n");
for (i = 0; i < n; i++)
{
Console.Write("\n");
for (j = 0; j < n; j++)
Console.Write("{0}\t", brr1[i, j]); // Print elements of the second matrix
}
/* Calculate the subtraction of the matrices */
for (i = 0; i < n; i++)
{
for (j = 0; j < n; j++)
crr1[i, j] = arr1[i, j] - brr1[i, j]; // Perform subtraction of elements and store in the resultant matrix
}
// Display the resultant matrix after subtraction
Console.Write("\nThe Subtraction of two matrices is : \n");
for (i = 0; i < n; i++)
{
Console.Write("\n");
for (j = 0; j < n; j++)
Console.Write("{0}\t", crr1[i, j]); // Print elements of the resultant matrix
}
Console.Write("\n\n");
}
}
Sample Output:
Subtraction of two Matrices : ------------------------------ Input the size of the square matrix (less than 5): 2 Input elements in the first matrix : element - [0,0] : 2 element - [0,1] : 4 element - [1,0] : 6 element - [1,1] : 8 Input elements in the second matrix : element - [0,0] : 1 element - [0,1] : 3 element - [1,0] : 5 element - [1,1] : 7 The First matrix is : 2 4 6 8 The Second matrix is : 1 3 5 7 The Subtraction of two matrix is : 1 1 1 1
