Aim:
To write a program in C# to perform conversion of dollars to rupees.
Algorithm:
ALGORITHM FOR COMPONENT.
Step 1: Create a namespace as currwithcomp.
Step 2: Create a class called currency as public.
Step 3: Inside the class declare the private variables x of type integer.
Step 4: Define a property variables x.
Step 5: In the property we have the get and set method.
Step 6: Get method is used to get the value form the user and set is used for
setting the user value to the original variables.
Step 7: Define a method called doll() as public.
Step 7.1: Return the value of x * 46.
Step 7.2: End of the method.
Step 8: End of the component.
AGORITHM FOR MAIN.
Step 1: Create a class called curr.
Step 2: Define the main function.
Step 2.1: Create an object ob for currency.
Step 2.2 : Get the value of x using Console.Readline() method.
Step 2.3: Print the converted value using Console.Writeline() method.
Step 2.4: End of the main.
Program:
COMPONENT
Code:
using System;
namespace CompCS
{
public class Conv
{
private int i=0,j=45;
public int varI
{
get{return i;}
set{i=value;}
}
public int sum()
{
return i*j;
}
}
}Code:
using System;
using CompCS;
class ConvertComp
{
public static void Main()
{
Conv obj = new Conv();
Console.WriteLine("Enter the dollar amount u want to convert:");
int x = int.Parse(Console.ReadLine());
obj.varI = x;
Console.WriteLine("Dollar value : {0}",obj.varI);
Console.WriteLine("Ruppes value : {0}",obj.sum());
}
}1.Create a dll file for the component
csc /target:library Convert.cs
2.Create an exe file for the main
csc /reference:Convert.dll ConvertComp.cs
3.Run the exe file
ConvertComp
Output:
Enter the dollar amount u want to convert:30
Dollar value : 30
Ruppes value : 1350
