I am trying to overload the Comparison Operators, to have them compare the RMR of two fitness trackers. I need to change the RMR from a double to an int for the comparison. How would I do this when the RMR is calculated by a function. Here is my code.
#include <iostream>
#include <fstream>
#include <string>
#include <iomanip>
#include "FitnessTracker.h"
using namespace std;
struct Activity
{
string name;
int burnForLo; // <150lbs
int burnForMed; // 150-250
int burnForHi; // >250
}info[12];
void CreateStruct(Activity info[], ifstream &Activities);
void StartTracker(FitnessTracker &Tracker);
char DisplayAndMenu(FitnessTracker &Tracker);
void AddCalories(FitnessTracker &Tracker);
void ExerciseMenu(Activity info[], int &exercise);
void CalculateCalsBurned(Activity info[], int &exercise, FitnessTracker &Tracker);
void EndDay(FitnessTracker &Tracker);
void main()
{
char Menu;
int exercise;
FitnessTracker Tracker(0, 0, 0, 'M');
ifstream Activities;
CreateStruct(info, Activities);
StartTracker(Tracker);
do
{
Menu = DisplayAndMenu(Tracker);
if (Menu == 'A' || Menu == 'a')
AddCalories(Tracker);
else if (Menu == 'D' || Menu == 'd')
{
ExerciseMenu(info, exercise);
CalculateCalsBurned(info, exercise, Tracker);
}

EndDay(Tracker);
}while (Menu != 'Q' && Menu != 'q');
}
