Question

Write code to read a list of song names and durations from input. Input first receives a song name, then the duration of that song. Input example: Time 424 Money 383 quit.

#include <iostream>
#include <string>
#include <vector>
using namespace std;

class Song {
public:
void SetNameAndDuration(string songName, int songDuration) {
name = songName;
duration = songDuration;
}
void PrintSong() const {
cout << name << " - " << duration << endl;
}
string GetName() const { return name; }
int GetDuration() const { return duration; }

private:
string name;
int duration;
};

int main() {
vector<Song> songPlaylist;
Song currentSong;
string currentName;
int currentDuration;
unsigned int i;

cin >> currentName;
while (currentName != "quit") {

/* Your code goes here */

}

for (i = 0; i < songPlaylist.size(); ++i) {
currentSong = songPlaylist.at(i);
currentSong.PrintSong();
}

return 0;
}
