Question

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

alot of people give me either partial answers, or incorrect skeleton. PLEASE YOU CAN'T CHANGE WHAT IS THERE, YOU CAN ONLY ADD.

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

}

infile.close();

}

void List(Candidate candidates[]) {

}

void Votes(Candidate candidates[]) {

}

void displayCandidate(Candidate candidates) {

}

Candidate First(Candidate candidates[]) {

}

Candidate Last(Candidate candidates[]) {

}

void Scores(Candidate candidates[]) {

}

***NOTE*** I HAVE BEEN EITHER GETTING PARTIAL ANSWERS, OR ANSWERS THAT OBVIOUSLY DID NOT READ AND FOLLOW WHAT NEEDS TO BE DONE.

FOR THE LOVE OF GOD. READ PLEASE. I KEEP ASKING QUESTIONS BUT NONE OF YOU ANSWER IT THE RIGHT WAY AND GIVE ME WHAT YOU WANT.
