The following
«include <iostream>
«include <fstream»
«include <cctype> // Needed for toupper
using namespace std;
int main()
{
// Define a file stream object here and use
// the file stream to open the file phones.dat
string name, phone;
cout << "This program allows you to add names and phone\n";
cout << "numbers to phones.dat.\n";
do
{
char add;
cout << "Do you wish to add an entry?";
cin >> add;
if (toupper(add) == 'Y')
{
// Write code here that asks the user for a name
// and phone number, then stores it in the file
}
} while (toupper(add) = 'Y');
// Don't forget to close the file.
return 0;

This DNA test measures the various parts of the sequence and assigns them a letter. While the letters could be anything from A to Z, the only letters that matter for this test are the letters {A,B,C,D} all other letters can be ignored completely. A sample will be tested, given a length of time and then tested again. Each time the scientist will generate a line of data.

Create a function with the following signature: nextBirthdate(filename, date) filename: parameter, which represents the CSV filename. date: parameter, which represents the current date. The function should open the CSV file, read the birthdate data, and determine which person's birthday will be celebrated next, given the current date. The name of the person should be returned. In other words, given a date, find the person whose birthday is next.
