Question

INPUT FILE INTO ARRAY. CHECKING FOR COMMAS AND SUCH. HOW TO DO? ****IMPORTANT**** PLEASE READ CAREFULLY ****IMPORTANT****

***GOALS***

HOW TO CHECK FOR COMMAS, TILL THE END OF FILE. IT WILL CHECK THE LINE FOR THE APPRORIATE FORMAT IN THE TEXT FILE. IF THERE IS MISSING A COMMA, IT WILL IGNORE, IF THERE IS A WHITE SPACE, IT WILL CORRECT AND READ LINE, IF IT IS MISSING 1 OF THE 3 INFORMATION, IT WILL IGNORE.

Display candidates’ names using displayList() function
 Execute the getWinner(Candidate[]) function to get the candidate with the highest number of votes. Display his name along with number of votes.
 Execute the getLast(Candidate[]) function to get the candidate with the lowest number of votes. Display his name along with number of votes.
 Calculate pScore for each candidate
 Sort candidates by votes
 Display sorted list using displayList() function
 For three records with the highest pScore, use the roundScore function to round the pScore
 Display list again using displayList() function

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* How would I do the readFile function? It says to check if the commas are present, and that the program will correct the line if there is white spaces. How do i use the find() function? 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 WHAT IS ALREADY THERE ON THE SKELETON, YOU MAY ADD EXTRA INFORMATION THOUGH:

#include <iostream>

#include <iomanip>

#include <string>

#include <stdlib.H>

#include <fstream>

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[]) {

Solution

code

void readFile(Candidate candidates[])
{
//Variables for taking the file, storing the lines into strings, and counting the amt of lines found.
string line;
ifstream infile;
int counter=0;

//Open file of cadidate data.
infile.open("elections.txt");
//Goes threw data in while loop.
while (!infile.eof())
{
getline(infile,line);//sets line in file to string variable.

//Finds proper format conditons in saved line of data.
int firstPos = line.find("F=");
int nextPos = line.find(",L=");
int thirdPos = line.find(",V=");

//Checks that line format conditions are true then stores it in struct array if true.
if (firstPos==0 && nextPos>0 && thirdPos>0)
{
//Sets the first name out of line.
candidates[counter].first = line.substr(2,line.find(",L=")-2);
//Cuts out used part of line.
line = line.substr(line.find(",L=")+3);
//Sets the last name from next part of line.
candidates[counter].last = line.substr(0, line.find(",V="));
//Cuts out used part of line up to votes.
line = line.substr(line.find(",V=")+3);
//Converts rest of string to double number.
double numVotes = atof(line.c_str());
//Stores double number into votes.
candidates[counter].votes = numVotes;
//Sets pScore as zero to start.
candidates[counter].pScore = 0;
//Increment counter.
counter++;
}
//If line of data isnt formatted properly, continue to next.
else
continue;
}

infile.close();
}
