Question

I need this solution using C++

Write a report over programming. Include numbers on your submission to identify which part of the assignment you are taking care of. 1. (10 points) Include a title that explains in a sentence what you learned or noticed. 2. (70 points) Include your code for the programming assignment Write a code to print to a csv file and read from a csv file 3. (10 points) The output of your code that shows what you have works. 4. (10 points) A conclusion that discusses what you learned or noticed during the assignment.

Answer 1

2)C++ code to print to an csv file:

1. #include <iostream.h> // inlcude iostream and string libraries
2. #include <fstream.h>
3. #include <string.h>
4. using namespace std;
5. ofstream outputFile; // create an ofstream for the file output
6. ofstream fs
7. filename = "exampleOutput.csv";// create a name for the file output std::string
8. int i; int A; int B; int C; // create some variables for demonstration
9. int main(int argc, char** argv)
10. {
11. fs.open(outputFile,filename); // create and open the .csv file
12. outputFile << "Column A" << "," << "Column B" << "Column C" << std::endl; // write the file headers
13. int i = 1;// i is just a variable to make numbers with in the file
14. for (int counter = 0; counter < 10; counter++)// write data to the file
15. {
16. A = i + 5; // make some data
17. B = i + 10;
18. C = i + 20;
19. outputFile << A << "," << B << "," << C << std::endl;// write the data to the output file
20. i = i * 5; // increase i
21. }
22. outputFile.close(); // close the output file
23. return 0;
24. }

C++ code to read from a csv file:

1. #include <string>
2. #include <vector>
3. #include <sstream> //istringstream
4. #include <iostream> // cout
5. #include <fstream> // ifstream
6. using namespace std;
7. /**
8. * Reads csv file into table, exported as a vector of vector of doubles.
9. * @param inputFileName input file name (full path).
10. * @return data as vector of vector of doubles.
11. */
12. vector<vector<double>> parse2DCsvFile(string inputFileName) {
13.     vector<vector<double> > data;
14.     ifstream inputFile(inputFileName);
15.     int i = 0;
16.     while (inputFile) {
17. i++;
18.         string s;
19.         if (!getline(inputFile, s)) break;
20.         if (s[0] != '#') {
21.             istringstream ss(s);
22.             vector<double> record;
23.             while (ss) {
24.                 string line;
25.                 if (!getline(ss, line, ','))
26.                     break;
27.                 try {
28.                     record.push_back(stof(line));
29.                 }
30.                 catch (const std::invalid_argument e) {
31.                     cout << "NaN found in file " << inputFileName << " line " << l
32.                          << endl;
33.                     e.what();
34.                 }
35.             }
36.             data.push_back(record);
37.         }
38.     }
39.     if (!inputFile.eof()) {
40.         cerr << "Could not read file " << inputFileName << "\n";
41.         __throw_invalid_argument("File not found.");
42.     }
43.     return data;
44. }
45. int main()
46. {
47.     vector<vector<double>> data = parse2DCsvFile("test.csv");
48.     for (auto l : data) {
49.         for (auto x : l)
50.             cout << x << " ";
51.         cout << endl;
52.     }
53.     return 0;
54. }
