# Assignment#1 Spring 2010 CS201: Introduction to Programming

Problem Statement: Exchange of currency rates

You are required to write a program for Currency Exchange rates. The basic idea is that user/reader will be able to interchange different currencies using our program. User will have three options i.e. Pakistani Rupees, US Dollars, and Euro.

Detailed Description:

1.  The program should display

Please select currencies that you want to exchange.

Description:

Enter ‘R’ for Pakistani Rupees.

Enter ‘E’ for Euro.

Enter ‘D’ for Dollar.

Then your program should take these inputs,

2.  Depending upon the choices that user has entered, your program will further display the prompt

3.  Then the program should take two inputs from the user as:

-----------------------------------------------------------------

Please select the currency that you want to convert :

Please select the currency that you want to convert into:

-----------------------------------------------------------------

4.  After getting both inputs, program will calculate the currency rates on the basis on this information.

1 Euro = 112 Rupees.

1 Dollar = 84 Rupees.

1 Euro = 1.33 Dollars

1 Dollar = 0.75 EUR

After calculating the conversion rate for the selected currencies display it on the screen.

In the end of the program, user should be asked if he/she wants to make another conversion.

If user presses y then the whole program should start again. If user presses n then the program should terminate.

Sample Output

 Dev c++ Output: Please select currencies that you want to exchange. Description:         Enter ‘R’ for Pakistani Rupees.         Enter ‘E’ for Euro.            Enter ‘D’ for Dollar.       Please select the currency that you want to convert : E              Please select the currency that you want to convert into: D     Please enter the amount in Euro : 12     12 Euro = 16 Dollars     Do you want to make another conversion? (y/n) : y     Please select currencies that you want to exchange.   Description:        Enter ‘R’ for Pakistani Rupees.        Enter ‘E’ for Euro.           Enter ‘D’ for Dollar.      Please select the currency that you want to convert : R             Please select the currency that you want to convert into: D      Please enter the amount in Rupees : 90      90 Rupees = 1.07143 Dollars      Do you want to make another conversion? (y/n) : n

Hints:

• You have to use if/else statements to switch among different currency combinations.
• For repeating the whole program again by prompting the user, you have to use a char variable “choice” which will take the choice of the user in yes or no (y or n). You can use while or do-while loop for this purpose.
• You must write your comments in critical areas of the program to explain the logic that you have used in that specific point. Do not use comments where they are not needed.
• The output of your program may differ with one or two digits after fraction point. It won’t be an issue of deduction of marks.

Tariq bhai mere pass to abhi tak books hi nai ponchi or computer pe b 1 lec tak nai parh saka bijli ki waja se.plz hlp me.
It is very easy to solve this assignment.
First you just creat the whole display of the output program with the help of " cout " statement.
Then start writing the calculation code sequentially with the help of " If Else" statement.
I think every one can solve it like this.

Take care
