Question
First, create and copy the below data (not the captions) into a file name Referees.dat
ID FName LName Grade
0001 Mike Apple CLUB
0012 Josh Boeing STATE
0103 Linda Intel STATE
0084 John Rambus NATIONAL
0205 Becky Sirius CLUB
0045 Tom Skyworks CLUB
0807 Kevin Suzuki NATIONAL
0074 Henry Xilinx STATE
You are to write a program to do the followings:
Define an enumeration type RefereeGrade including 5 values UNKNOWN, CLUB, STATE, NATIONAL and FIFA.
Define a structure named SReferee containing data members for the following information:
· Id (typed string)
· First Name (typed string)
· Last Name (typed string)
· Grade (typed RefereeGrade)
Then, create an array of 30 elements typed SReferee to read the data from the file Referees.dat into this array.
Create a menu with the following options:
1.List all referees
2.List all referees of a specific grade
3.List all referees with grade less than a specific grade
4.List all referees with grade more than a specific grade
5.List information of a specific referee using the Id
6.List information of a specific referee using the names
7.Add a referee
8.Remove a referee using Id
9.Update referee grade using Id
10.Quit
For option Quit, before quitting your program, you have to write all referee information back to the file Referees.dat to keep the updated information of referees.
The coding language is c++ and I have to get it done by saturday so hopefully that is a good amount of time.
And if you could comment a lot so i could see what each line does, that would be great.
My teacher gave this skeleton/frame to use so if you could copy and paste it and do it from there that would be amazing:
#include <iostream>
#include <string>
using namespace std;
struct SReferee
{
// Your definition here
};
int menu ();
void listAllReferees ();
void listRefereesOfSpecificGrade ();
void listtRefereesWithGradeLessThanSpecificGrade ();
void listtRefereesWithGradeMoreThanSpecificGrade ();
void listtRefereeInfoWithId ();
void listtRefereeInfoWithNames ();
void addNewReferee ();
void removeReferee ();
void updateRefereeGrade ();
void Quit();
SReferee referees[30];
// Function to read referee information from the file Referees.dat
void readRefereeInfo();
// Function to write referee information back to the file Referees.dat
void writeRefereeInfo();
void main()
{
// Read referee information from the file Referees.dat
readRefereeInfo();
int choice;
do {
system("CLS");
choice = menu();
switch (choice) {
case 1:
listAllReferees ();
