C# Sharp Exercises: Display the upper triangular of a given matrix
C# Sharp Array: Exercise-27 with Solution
Write a program in C# Sharp to print or display the upper triangular of a given matrix.
Sample Solution:-
C# Sharp Code:
using System;
public class Exercise27
{
public static void Main()
{
int i,j,n;
int[,] arr1 = new int[50,50];
Console.Write("\n\nDisplay the upper triangular of a given matrix :\n");
Console.Write("----------------------------------------------\n");
Console.Write("Input the size of the square matrix : ");
n = Convert.ToInt32(Console.ReadLine());
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());
}
}
Console.Write("The matrix is :\n");
for(i=0;i<n;i++)
{
for(j=0;j<n ;j++)
Console.Write("{0} ",arr1[i,j]);
Console.Write("\n");
}
Console.Write("\nSetting zero in upper triangular matrix\n");
for(i=0;i<n;i++)
{
Console.Write("\n");
for(j=0;j<n;j++)
if(i>=j)
Console.Write("{0} ",arr1[i,j]);
else
Console.Write("{0} ",0);
}
Console.Write("\n\n");
}
}
Sample Output:
Display the upper triangular of a given matrix : ---------------------------------------------- Input the size of the square matrix : 3 Input elements in the first matrix : element - [0],[0] : 1 element - [0],[1] : 2 element - [0],[2] : 3 element - [1],[0] : 4 element - [1],[1] : 5 element - [1],[2] : 6 element - [2],[0] : 7 element - [2],[1] : 8 element - [2],[2] : 9 The matrix is : 1 2 3 4 5 6 7 8 9 Setting zero in upper triangular matrix 1 0 0 4 5 0 7 8 9
