Finging the highest charges in an array

HI ALL. I'M LOOKING FOR A SOLUTION FOR MY CODE. I WANT TO FIND THE HIGHEST CHARGE AFTER AN ARRAY HAS SHOWN UP(SPEAKER'S FEE). WHAT CAN I DO??
THANKS

HERE'S MY CODE:

#include "stdafx.h"
#include <iostream>
#include <iomanip>
using namespace std;

struct Bureau
{
	char name[50];		// Name
	char phoneNum[50];	// Phone number
	char topic[50];		// Speaking topic
	float fee;			// Charges of speaker
};

int main()
{
	Bureau person[200];	// Array of structures
	int index = 0;		// Loop counter
	int speakers;		// Number of speakers to be reserved
	
	
	// Get the number of speakers to be reserved.
	cout << " How many speakers need to be reserved? ";
	cin >> speakers;
	while (speakers < 0 || speakers > 200)
	{
		cout << " Please enter a valid number that do not lesser than zero or greater than two hundred. " << endl;
		cin >> speakers;
	}
		cout << endl << endl;
	
	for (int count = 0; count <= 50; count++)
	{
		// Get the information of speaker.
		cout << " Bureau for speaker: " << (count + 1) << endl;
		cout << " Enter the speakers name: ";
		cin.ignore();
		cin.getline(person[count].name, 50);
		cout << " Enter the phone number of " << person[count].name << " : ";
		cin >> person[count].phoneNum;
		cout << " Enter the topic of " << person[count].name << " : ";
		cin.ignore();
		cin.getline(person[count].topic, 50);
		cout << fixed << showpoint << setprecision(2);
		cout << " Enter the fee of " << person[count].name << " : ";
		cin >> person[count].fee;
		while (person[count].fee <0)		// Input Invalidation
		{
			cout << " Please enter a positive amount. ";
			cin >> person[count].fee;
		}
		cout << endl << endl;
		
		// Display a list of speaker information.
		cout << " Name: " << person[count].name << endl;
		cout << " Phone number: " << person[count].phoneNum << endl;
		cout << " Topic: " << person[count].topic<< endl;
		cout << " Fee: $ " << person[count].fee << endl << endl;
	}
	
	return 0;
}
