Question
Using C++ ,Give the user menu three options, including:
Option A: Display a report showing the energy produced and the percentage of the grand total energy for each of the 13 types of energy for a given year. Prompt the user to enter the year.
Example: If the user enters 1994, the report might look like:
Energy produced by different sources for the year 1994:
Category Energy (Thousand Kilowatthours) Percentage of total energy
Coal 1666276091 53.947%
Petroleum 98676618 3.195%
Natural Gas 385689325 12.487%
