Use C++

Write a program that keeps track of a speakers' bureau. The program should use a structure to store the following data about a speaker:

Name

Telephone Number

Speaking Topic

Fee Required

The program should use an array of at least 10 structures. It should let the user enter data into the array, change the contents of any element, and display all the data stored in the array. The program should have a menu-driven user interface.

Input Validation: When the data for a new speaker is entered, be sure the user enters data for all the fields. No negative amounts should be entered for a speaker's fee.

Please, comment your code.

#include <cstdlib>
#include <iostream>
#include <string>

using namespace std;

// Structure lists
struct speakerInfo

string name;
string phoneno;   
string speakTopic;  
int feeReq;
};

//Function prototypes
void getSpeaker(speakerInfo *);
void printSpeaker(speakerInfo *);
void editSpeaker(speakerInfo *);

int main()

int NUM_SPEAKERS = 10; //The number of speakers
int index; //Loop counter...

//Choice for menu

const int enter = 11,
