C++ PROGRAM

Running the Race (class runner)
Write a program that asks for the names of five runners and the time it took each of them to finish a race. The program should display who came in first, second, and third place

Input Validation: Only accept positive numbers for the times.   

The program should include:
-Constructor (default, copy constructor, with parameters, default arguments

-In the main program:
-Define a dynamic array composed of runner instances, where the number of runners is given by the user.

- The program must contain functions of:
-To Enter the information of the runners and their respective times. -
-Function:to Prints the first three positions.
-Function: to sort by the parameter of the times in the runners in ascending order.

- Validate your program with five runners.

- Implement the program Using Dynamic Memory in the name of the runner

-Implement other program using a string type variable in the name of the runner

Explanation / Answer

#include<iostream>

using namespace std;

class runner{
private:
   string* names;
   double* time;
   int count;
public:
   void acceptRunners() {
       cout << "Enter number of runners: ";
       cin >> count;
       names = new string[count];
       time = new double[count];

       for (int i = 0; i < count; i++) {
           cout << "Enter name of player " << i+1 << ": ";
           cin >> names[i];
           do {
               cout << "Enter time of player " << i+1 << ": ";
               cin >> time[i];
           } while(time[i] < 0);

       }
   }

   void sort() {
       for(int i = 0; i < count -1; i++)
           for(int j = 0; j < count - i - 1; j++)
               if (time[j] > time[j+1]) {
                   double tmp_time = time[j];
                   time[j] = time[j+1];
                   time[j+1] = tmp_time;

                   string tmp_name = names[j];               names[j] = names[j+1];
                   names[j+1]= tmp_name;

               }

   }

   void printWinners() {
       for (int i = 0; i < (count < 3? count:3); i++) {
           cout << "Rank "<< (i+1) << ": "
<< names[i] << " time: " << time[i] << endl;
       }
   }
};

int main() {
   runner r;
   r.acceptRunners();
   r.sort();
   r.printWinners();
}
