Question

Step 2: Create the method specified below.

static int GetValidWidth(string prompt)

Input parameters

prompt: message for user describing the input required

Returns

A non-zero width entered by the user

Step 3: Create the method specified below.

static int GetValidHeight(string prompt)

Input parameters

prompt: message for user describing the input required

Returns

A non-zero positive height entered by the user

Step 4: Create the method specified below.

static void DisplayBox(int width, int height, char fillChar)

Input parameters

width: width of each row of the box

height: number of rows in the box

fillChar: character to draw the box with

Outputs

Displays the specified box and fills it with repetitions of fillChar.

Step 5: From the main() method, prompt and retrieve the width of the box by calling the GetValidWidth(string) method, and the height by calling GetValidHeight(string) using appropriate prompts and then read in a fill character for the box (assume valid input), call the DisplayBox(int,int,char) method to display a filled box.

Step 6: Test your program using the following test plan.

Test Plan
Test case	Test Data	Expected result	Checked
Width Height Draw box with	5 6 %	%%%%% %%%%% %%%%% %%%%% %%%%% %%%%%
Width Height Draw box with	10 5 *	********** ********** ********** ********** **********

Coding Requirements

The following coding standards must be followed when developing your program:

• A C# comment block at the beginning of the source file describing the purpose, input, process, output, author, last modified date of the program such as shown below:
• Write only one statement per line.
• Write only one declaration per line.
• Use camelCase for local variable names and method arguments.
• Use PascalCase for method name and constant variable names.
• If continuation lines are not indented automatically, indent them one-tab stop (four spaces).

The language should be used is Csharpfor the code

Answer 1

Answer = We need to print Box with specific width, height and character specified by user. The program is in "C#" language and comments are shown by "//" operator.

Source Code:

using System.IO;
using System;
// Program class in C#
class Program
{
// Method of class to take width of box
static int GetValidWidth(string prompt){
Console.WriteLine(prompt);
string value=Console.ReadLine();
int width=Convert.ToInt32(value);
return width;
}
// Method to take height of box
static int GetValidHeight(string prompt){
Console.WriteLine(prompt);
string value=Console.ReadLine();
int height=Convert.ToInt32(value);
return height;
}
// Method to display Box on Display
static void DisplayBox(int width, int height, char fillChar){
for (int i = 1; i <= height; i++)
{
for (int j = 1; j <= width; j++)
{
Console.Write(fillChar);
}
Console.WriteLine();
}   
}
// Main function
public static void Main()
{
// call method to take width
int width=GetValidWidth("Enter Width of Box: ");
Console.WriteLine(width);
// cal method to take height
int height=GetValidHeight("Enter Height of Box: ");
Console.WriteLine(height);
// take character input to display box
Console.WriteLine("Enter character to draw the box: ");
char fillChar=Console.ReadLine()[0];
Console.WriteLine(fillChar);
// call method to display box
DisplayBox(width,height,fillChar);
}
}

Output:

Enter Width of Box: OT Enter Height of Box: 9 Enter character to draw the box: % 70707070707070707070 ////////// 70707070707070707070 ////////// 70707070707070707070 ////////// 70707070707070707070 ////////// 70707070707070707070 ////////// 7070707070707070707 //////////

This is the screenshot of output of above program.
