Question

1. Modify the program to output that line N times. That is, output a square of N lines each with N characters. Example output for parameters N=5 and S="*" should appear as follows: 多多本事事 串串串串串 事事事串串 事事事事事 2. Modify the DrawChars method so that the number of the line appears at that position within the line. That is, line i must have N-1 copies of S with the additional character in place i that must be the least significant digit of the number i. Note that you will need to add an extra parameter to know what position, or line, you are currently drawing. Example output for parameters N=11 and S="*" should appear as follows: 2本來車車座座 率*3串串串串串串图库 本本本市5本陣陣陣海库 本本本本石車車座座率 多多本中中中了李李李李 多多本事本本8*本客 多多本事李李李李李 来来来来来来来李** 多多多多多多多*1

Below is the code in C# for the above question:

*********************** 1. ***********************
using System;
using System.Collections.Generic;
using System.Text;

namespace PracP1
{
public class Program
{
public static void Main(string[] args)
{
int n = 0;
string s = "";

// check if 2 arguments
if(args.Length == 2)
{
if(int.TryParse(args[0],out n))
{
// successful parse to use n
s = args[1]; // Second argument is character
// draw a line of characters
DrawChars(n, s);
}
else
{
// Unsuccessful parse so no n value
}
}

// Wait for user to have read the output.
Console.WriteLine();
Console.Write("<Press enter to finish>");
Console.ReadLine();
}

static void DrawChars(int n,string s)
{
// this gives the square of n lines each with n character s
for(int i=0;i < n; i++)
{
for(int j=0;j< n; j++)
{
Console.Write(s);
}
Console.WriteLine();
}
Console.WriteLine();
}
}
}

static void DrawChars(int n,string s)
{
// integer variable k that keep track of line number
int k = 1;
for(int i=1;i <= n; i++)
{
for(int j=1;j<= n; j++)
{
// if j is equal to i then print the number k
if (j == i)
{
Console.Write(k);
}
// else print the character.
else
{
Console.Write(s);
}

}
// incrementing k by 1.

// if k becomes greater than 9 then set k to 0.
if (k > 9) k = 0;
Console.WriteLine();
}
Console.WriteLine();
}
}
}

Refer to the screenshot attached below to better understand the code and indentation:

Output:

1. N = 5 and S = "*"

2. N = 11 ans S = "*"
