C++ help fix my dynamic array program

#include  #include  #include  #include  #include  using namespace std; struct Classes { string names; //Holds names of the students string *courses; //Number of students int num; //Holds the courses the student is taking }; int main(int argc, const char * argv[]) { fstream fin; fin.open ("courses.txt"); int size; //Number of students fin >> size; Classes * a = new Classes[size]; //Array of struct which holds a students name and classes char el; fin.get(el); for (int ct = 0; ct > a[ct].num; a[ct].courses = new string [a[ct].num]; //Array that holds a student courses for ( int ct2=0; ct2 > a[ct].courses[ct2]; } fin.get(el); } cout > choice; while (choice != 'Q') { if (choice == 'D') { cout > courses; cout > choice; } system("pause"); } 

courses.txt looks like this:
