C# Console Application program to Create a user defined matrix and find Lowest number [closed]

by

Put this outside your “main” method to get make sure the user gives a number.

private static int GetNumber(string request)
{
    bool succeeded = false;
    Console.WriteLine(request);
    string reply="";
    while(!succeeded)
    {

        reply = Console.ReadLine();
        try
        {
            int.Parse(reply);//Attempt to convert "reply" into an integer.
            succeeded = true;
        }
        catch
        {
            Console.WriteLine(request+" (make it a number)");
        }
    }
    return int.Parse(reply);
}

And then use this for your main method.

public static void Main()
{
    int rows = GetNumber("Enter no of Rows:");
    int columns = GetNumber("Enter no of Columns:");
    int[,] matrix = new int[rows,columns];
    for(int row = 0; row < rows; row++)
    {
        for (int column = 0; column < columns; column++)
        {
            matrix[row,column] = GetNumber("Enter value for sector Row: "+(row+1)+" Column: "+(column+1));
        }
    }
    int smallestnumber = matrix[0,0];
    for(int row = 0; row < rows; row++)
    {
        for (int column = 0; column < columns; column++)
        {
            if(matrix[row,column] < smallestnumber)
            {
                smallestnumber = matrix[row,column];
            }
        }
    }
    Console.WriteLine("Lowest number is: "+smallestnumber);
}

I took a liberty here as your example says “Enter row value 1…Enter column value 2” however each individual value in a matrix would be represented by both a row and a column.
