The following problem in C++ ?
Repetition
Write a program that reads an exchange rate for converting English currency to U.S. currency and then reads several values in English currency and converts each amount to the equivalent U.S. currency. Display all amounts with appropriate labels. Use sentinel-controlled or end-of-file-controlled loops for the input.
In this program you will learn the use of loops to repeatedly take input from the user and also about sentinel or guard to known when to stop taking inputs from the user.
The program is well-documented with comments so that it can be easily understood.
