Question

Hello, I need to divide my code in this different parts.

Use a standard approach to source files in this assignment: a .cpp for each function (you have at least two – main and ageCalc) a header file for the student struct, properly guarded

Code:

#include <iostream>

#include <string>

#include <fstream>

#include <algorithm>

#include <vector>

#include <iomanip>

using namespace std;

#define nullptr NULL

#define MAX_SIZE 100

struct Student

{

    string firstName;

    char middleName;

    string lastName;

    char collegeCode;

    int locCode;

    int seqCode;

    int age;

};

struct sort_by_age

{

    inline bool operator()(const Student *s1, const Student *s2)

    {

        return (s1->age < s2->age);

    }

};

int ageCalc(Student *studs[], Student *&youngest);

int main()

{

    Student *students[MAX_SIZE] = {nullptr};

    ifstream Myfile;

    Myfile.open("a2data.txt");

    if (!Myfile.is_open())

    {

        cout << "Could not open the file!";

        return 1;

    }

    vector<string> words;

    string line;

    while (!Myfile.eof())

    {

        getline(Myfile, line);

        line.c_str();

        int i = 0;

        string word = "";

        while (line[i] != '\0')

        {

            if (line[i] != ' ')

            {

                word = word + line[i];

                i++;

            }

            else

            {

                if (word != "")

                    words.push_back(word);

                word = "";

                i++;

            }

        }

        words.push_back(word);

    }

    Myfile.close();

    int count = 0;

    string fname = words.at(count);

    count++;

    int n = 0;

    while (count < words.size() - 2)

    {

        Student *s = new Student;

        s->firstName = fname;

        string mname = words.at(count);

        s->middleName = mname[0];

        count++;

        s->lastName = words.at(count);

        if (words.at(count).size() >= 12)

        {

            if (words.at(count)[1] >= '0' && words.at(count)[1] <= '9')

            {

                count--;

                s->middleName = ' ';

                s->lastName = words.at(count);

            }

        }

        count++;

        string id = words.at(count);

        count++;

        s->collegeCode = id[0];

        string loc = "";

        loc = loc + id[1];

        loc = loc + id[2];

        s->locCode = stoi(loc);

        string seq = "";

        for (int j = 3; j < 9; j++)

        {

            seq = seq + id[j];

        }

        s->seqCode = stoi(seq);

        string age = "";

        age = age + id[9];

        age = age + id[10];

        age = age + id[11];

        s->age = stoi(age);

        fname = id.erase(0, 12);

        students[n] = s;

        n++;

    }

    words.clear();

    sort(students, students + n, sort_by_age());
