I am trying to read a text file into a cstring array with struct/union implementations. First off, this is what my text file looks like:
F South Korea
Male Psy Park Jae Sang
31 - 12 - 1977
3 CSCI114 55 CSCI103 44 GangNam 100
S Female Super Junior
5 - 8 - 1978
2 CSCI114 60 CSCI103 80
F People Republic Of China
Unknown James Bond
11 - 12 - 1976
4 CSCI114 54 CSCI124 66 CSCI007 99 CSCI123 28
Now, ignoring the obvious Asian popstar references my lecturer decided to fill this example with - I'd like to be able to read the first number before the CSCI, which is the number or courses and their respective grades and automate(loop) it for all the 3 (or possibly more) students in the text file.
I have not written any code for what I'm trying to describe here but here is what I have so far.
#include <iostream>
#include <fstream>
#include <cstdlib>
#include <ctime>
using namespace std;
const int MAX = 80;
struct Birthday
{
char day[MAX];
char month[MAX];
char year[MAX];
};
struct Local
{
char name[MAX];
char gender[MAX];
Birthday bd;
char subjects [MAX];
};
struct Foreigner
{
char name[MAX];
char nationality[MAX];
char gender[MAX];
Birthday bd;
char subjects [MAX];
};
union Student
{
Local localStudent;
Foreigner foreignStudent;
};
enum CountryType {S, F};
struct UowStudents
{
CountryType ct;
Student st;
};
int fileToArray (fstream& afile, char fileName [], UowStudents& x);
int main ()
{
srand(time_t(NULL));
fstream afile;
UowStudents x [MAX];
char fileName[MAX];
cout << "Enter filename: ";
cin >> fileName;
int size = fileToArray (afile, fileName, *x);
}
int fileToArray (fstream& afile, char fileName [], UowStudents& x)
{
afile.open(fileName, ios::in);
if (!afile)
{
cout << fileName << "could not be opened for read" << endl;
exit (-1);
}
//file to array.
char locale;
char dateJunk;
afile >> locale;
afile.getline(x.st.foreignStudent.nationality, MAX);
afile >> x.st.foreignStudent.gender;
afile.getline(x.st.foreignStudent.name, MAX);
afile >> x.st.foreignStudent.bd.day;
afile >> dateJunk;
afile >> x.st.foreignStudent.bd.month;
afile >> dateJunk;
afile >> x.st.foreignStudent.bd.year;
//Tests my cstring arrays to see everything is copied in correctly.
cout << locale << " " << x.st.foreignStudent.nationality;
cout << endl;
cout << x.st.foreignStudent.gender;
cout << x.st.foreignStudent.name;
cout << endl;
cout << x.st.foreignStudent.bd.day << " - ";
cout << x.st.foreignStudent.bd.month << " - ";
cout << x.st.foreignStudent.bd.year;
return 0;
}
This is what my final text file with all the array information processed, would look like:

Any help is appreciated, thanks.
You can read in each course list this way:
int numOfCourses;
afile >> numOfCourses;
for (int i = 0; i < numOfCourses; i++)
{
string course;
afile >> course;
int grades;
afile >> grades;
// Fill in structure from `course` and `grades`...
}
