I just did formula to convert foriegn currency into US dollars below.

#include<iostream.h>

double amount = 0.0; /*Stores user input*/

int main()
{
cout<<"Currency Conversion"<<endl;

cout<<"--------------------\n";

cout<<"Enter the amount in US Dollar: "; /*Prompt user for amount*/

cin>>amount; /* Read in the amount*/

/*Convert the amount to each currency type and print it out*/

cout<<amount<<" US Dollars = "<<amount/0.6072<<" Swiss Francs\n";
cout<<amount<<" US Dollars = "<<amount/1.4320<<" British Pounds\n";
cout<<amount<<" US Dollars = "<<amount/0.0081<<" Japanese Yens\n";
cout<<amount<<" US Dollars = "<<amount/0.6556<<" Canadian Dollars\n";
cout<<amount<<" US Dollars = "<<amount/0.8923<<" Euros\n";

}

Now I am trying to write code for a menu (displayed as a loop) that allows users to choose which currency and the amount of the foreign currency they wish to convert to US dollars. Function(s) (besides main()) must be used.
