C# programming ? Part-1 @tabular

SUNIL GUTTA

Hi there

Write an application that allows a user to input the height and width of a rectangle and output the area and perimeter. Use methods for entering the values, performing the computations, and displaying the results. Results should be formatted and printed in a tubular display.

Should be named Rectangle
Prompt the user for the height and width in Main()
Pass the height and width to a method named ComputeArea() that returns the area back to

main

Pass the height and width to a method named ComputePerimeter() that returns the

perimeter back to main

Pass the height, width, area and perimeter to a method named DisplayResults() that displays

the results

Should look like this: http://i.imgur.com/mJSQyzG.png

Try this:

using System;

class Program
{
static void Main()
{
double height, width;
GetValues(out height, out width);
double area = ComputeArea(height, width);
double perimeter = ComputePerimeter(height, width);
DisplayResults(height, width, area, perimeter);
Console.ReadKey();
}

static void GetValues(out double height, out double width)
{
Console.Write("Enter the height: ");
height = double.Parse(Console.ReadLine());
Console.Write("Enter the width: ");
width = double.Parse(Console.ReadLine());
Console.WriteLine();
}

static double ComputeArea(double height, double width)
{
return height * width;
}

static double ComputePerimeter(double height, double width)
{
return (height + width) * 2.0;
}

static void DisplayResults(double height, double width, double area, double perimeter)
{
Console.WriteLine("Summary of Rectangle Measurements\n");
Console.WriteLine("Height: {0:F2}", height);
Console.WriteLine("Width: {0:F2}", width);
Console.WriteLine("Area: {0:F2}", area);
Console.WriteLine("Perimeter: {0:F2}", perimeter);
}
}

The program could use some data validation to make sure the height and width are > 0 but otherwise is complete.

Sure, just change the DisplayResults method to this:

static void DisplayResults(double height, double width, double area, double perimeter)
{
Console.ForegroundColor = ConsoleColor.Black;
Console.BackgroundColor = ConsoleColor.White;
Console.WriteLine("Summary of Rectangle Measurements".PadRight(80, ' '));
Console.WriteLine("Height: : {0,7:F2}", height);
Console.WriteLine("Width: : {0,7:F2}", width);
Console.WriteLine("Area : {0,7:F2}", area);
Console.WriteLine("Perimeter : {0,7:F2}", perimeter);
Console.ForegroundColor = ConsoleColor.White;
Console.BackgroundColor = ConsoleColor.Black;
}

Humm yes :) can't we keep some white backgroud so we can sure knew that the output is displayed in tabular thing rather on console directly ??

Thank you very very much
