Question

How do i find the highest ratio in a file using c++?

I have the code that already averages out the info in a certain txt file:

I understand that i could use an 'if' statement to sort out the info, but how would that be written?

this is the info in the txt file:

10
52   58
145   70
261   90
98   66
78   35
99   45
233   130
66   25
42   15
307   180

(the "10" is number of lines; first column represents the total_number_of_monsters_killed; second column represents the total_number_of_minutes_played ).

Explanation / Answer

The complet C++ code

#include <iostream>
#include <fstream>

using namespace std;

//TODO:
//Write the game with the best monster kill / time ratio to a file

void main() // int main()
{
        ifstream in_file;
        in_file.open("lol_stats.txt");

        int number_of_games_played = 0;
        in_file >> number_of_games_played;

        double total_number_of_monsters_killed = 0.0;
        double total_number_of_minutes_played = 0.0;
        double Best_ratio = 0.0; // variable to store the best ratio
        double Best_monster_kills = 0.0;// variable to store monster_kills for best ratio
        double Best_time_in_minutes = 1.0;// variable to store time_in_minutes for best ratio
        for (int i = 0; i < number_of_games_played; i++)
        {
                double monster_kills, time_in_minutes, ratio;

                in_file >> monster_kills;
                in_file >> time_in_minutes;

                total_number_of_monsters_killed += monster_kills;
                total_number_of_minutes_played += time_in_minutes;
              
                ratio = monster_kills/time_in_minutes;// Evaluating the ratio
                if(Best_ratio < ratio) // Find the best ratio by comparison
                {
                       Best_ratio = ratio; // updating the Best ratio
                       Best_monster_kills = monster_kills;// updating the Best_monster_kills
                       Best_time_in_minutes = time_in_minutes;// updating the Best_time_in_minutes
                }
        }

        double avg_number_of_monsters_killed_per_minute = 0.0;
        avg_number_of_monsters_killed_per_minute = total_number_of_monsters_killed / total_number_of_minutes_played;

        cout << "avg_number_of_monsters_killed_per_minute: " << avg_number_of_monsters_killed_per_minute << endl;
        cout << " The highest ratio = " << Best_monster_kills << "/" << Best_time_in_minutes << " = " << Best_ratio << endl;// result

        getch(); //return 0;
}

OUTPUT

avg_number_of_monsters_killed_per_minute: 1.93417
The highest ratio = 261/90 = 2.9
