將任意數字的特定單詞讀入一個cstring

Question

我試圖用struct/union實現將文本文件讀入一個cstring數組。首先，這是我的文本文件看起來像：

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 

現在，忽視了明顯的亞洲popstar引用我的講師決定，以填補這個例子 - 我希望能夠之前閱讀的第一個數字CSCI，這是數字或課程及其各自的成績，並自動化（循環）文本文件中的所有3（或更多）學生。

我沒有寫任何代碼來描述我在這裏要描述的內容，但這裏是我到目前爲止的內容。

#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; 
} 

這是處理所有的陣列信息我最後的文本文件，是什麼樣子：

任何幫助表示讚賞，感謝。

可以在每門課程表中讀這樣：

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`... 
}
