Question

Electricity is generated nationwide from a number of sources, including coal, nuclear, hydroelectric, wind, and more. The Department of Energy publishes various reports each year related to energy. Some of the reports are located at http://www.eia.doe.gov/emeu/aer/elect.html . One of the reports is: Table 8.2b Electricity Net Generation: Electric Power Sector, 1949-2013. A subset of this table for 1980 – 2015 (with formatting and headings removed) is available on Blackboard   in the data file is named Energy Data.dat. It is shown below.

The file Energy.dat is arranged as follows: Column 1 contains the year.

Columns 2-14 contain the following information:

Column

Energy (in Million Kilowatt-hours) generated by

Energy Category

2

Coal

Fossil Fuel

3

Petroleum

Fossil Fuel

4

Natural Gas

5

Other Gases

6

Nuclear Electric Power

7

Hydro-Electric Pumped Power

8

10

Program Requirements

Write a C++ program according to the following requirements:

1. Open the data file Energy.dat and read each column into an array (13 arrays total).

2. In addition to the 13 energy categories, create arrays for 3 useful totals:

Total Fossil Fuel Energy (sum of all fossil fuels)

Total Renewable Energy (sum of all renewable sources)

Grand Total Energy (sum of all 13 types of energy)

3. 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 2013, the report might look like:

Energy produced by different sources for the year 2013:

Category

Energy (Million Kilowatt-hours)

Percentage of total energy

Coal

1572179.442      

9.382385

Petroleum

24094.141

0.143788

Natural Gas

1019962.207

6.086887

Option B: Determine the year in which the peak production of energy occurred (absolute value) for any of the 16 categories (13 in the table and the three totals). Also display the value of the energy.

Example: if the user selects nuclear as the category, the output might be:

The peak production of energy by nuclear power of 806968.301 million kilowatt hours occurred in 2010

Option C: Create an output data file to be later opened by Excel in order to graph. Allow the user to specify the name of the file. Submit the output file under assignments. Call the file Option C.txt.

Any of the 16 categories of energy for a given year (for example, Wind Energy or Total Renewable Energy)

Additional Requirement: Allow the user to correct any bad inputs (invalid year or menu selection, etc.)

Test Cases: Run the program for the following test cases and submit the results:

Option A: Generate reports for 1994, 2015 and at least one more year.

Option B: Generate reports for Wind Energy, Total Renewable and two more choices

Explanation / Answer

#include <fstream>
#include <iostream>
#include <string>
using space std;

int main()
{

ifstream inFile;

int neglible[300]; //size of arrays bigger than number of entries in data file
int series1[100];
int series2[100];

int i=0;
inFile.open("happiness.dat");
if (inFile.fail())
{
cout << "Error" << endl;
return 1;
}
while (!inFile.eof())
{
inFile >> neglible[i];
inFile >> series1[i];
inFile >> series2[i];
i++;

cout << series1[i] << endl; // display values in the array to check that the correct values have been imported   
}
inFile.close();

return 0;

}
