Question

INPUT FILE INTO ARRAY. CHECKING FOR COMMAS AND SUCH. PLEASE READ CAREFULLY.

void readFile(Candidate candidates[]) – reads the elections.txt file, fills the candidates[] array. Hint: use substr() and find() functions. Set Score to 0.

void List(Candidate candidates[]) – prints the array of Candidate structs. One candidate per one line, include all fields. Use setw() to display nice looking list.

void displayCandidate(Candidate candidates[]) – prints the complete information about the candidate

.
Candidate First(Candidate candidates[]) – returns single struct element: candidate with highest score

Candidate Last(Candidate candidates[]) – returns single struct element: candidate with lowest score

void Votes(Candidate candidates[]) – function sorts the candidates[] array by number of votes, the order in candidates[] array is replaced

void Scores(Candidate candidates[]) – calculates the percentage score for each candidate. Use the following formula: ??????=(CandidateVotes)/(sum of votes)*100%

Correct line for the reference: F=John,L=Smith,V=3342

The line errors that your program needs to detect, are as follows:

incorrect token / separator, example in line 5: F=Steven,L=JohnV=4429 --- (comma missing) – lines with this error need to be ignored

space in token, example in line 3: F=Hillary,X=Clinton, V=1622 --- lines with this error need to be read, error fixed, data included in your dataset

empty line, example in line 6 – empty lines need to be ignored

Example Textfile

F=Michael,L=John,V=3342

F=Danny,L=Red,V=2003

F=Hillary,L=Clinton, V=1588

F=Albert,L=Lee,V=5332

F=Steven,L=JohnV=4429

*IMPORTANT* Please be DETAILED in explanations of each part of code. Beginner Coder. *IMPORTANT*

Code Skeleton We HAVE to follow. How Would i go about using this skeleton? YOU CANNOT CHANGE FUNCTIONS OF VARIABLES, BUT YOU MAY ADD TO IT. THE CODE MUST HAVE WHAT IS LISTED IN THE SKELETON CODE:

#include <iostream>

#include <iomanip>

#include <stdlib.h>

#include <fstream>

#include <string>

using namespace std;

struct Candidate {
string Fname;
string Lname;
int votes;
double Score;
};

const int MAX_SIZE = 100;

void readFile(Candidate[]);

void List(Candidate[]);

void Votes(Candidate[]);

void displayCandidate(Candidate);

Candidate First(Candidate[]);

Candidate Last(Candidate[]);

void Scores(Candidate[]);

int main() {

}

void readFile(Candidate candidates[]) {

string line;

ifstream infile;

infile.open("elections.txt");

while (!infile.eof()) {

getline(infile,line);

// your code here
