Question

C++

I need to make a program to help keep score. The program should first ask for the number of players in the game and the number of rounds to be played. Based on the number of players, the program should then ask for the names of the players and write them to a file. If no file exists, the program should create one. For each of the rounds, the program should accept the scores for each of the players. After each round, append the scores to the file.

Answer 1

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

int main() {
    string name, fileName;
    cout << "Enter file name: ";
    cin >> fileName;
    ofstream out(fileName.c_str(), ios_base::app);
    int n, rounds, score;
    cout << "Enter number of players? ";
    cin >> n;
    cout << "Enter number of rounds? ";
    cin >> rounds;

    for (int i = 0; i < rounds; ++i) {
        out << "Round " << i+1 << endl;
        out << "--------------------" << endl;
        for (int j = 0; j < n; ++j) {
            getline(cin, name); // read newline character
            cout << "Enter name: ";
            getline(cin, name);
            cout << "Enter score: ";
            cin >> score;
            out << name << ": " << score << endl;
        }
        out << endl;
    }

    out.close();
    return 0;
}
