Mass Class Declaration

[bigggnick]

Hello all,

I am new to C++ and have a question for everyone. I want to create a bunch of different object classes. For example, if I had an object called student, where each student has a name and id. The id is also the name of the object of student. So if I wanted to make 10 new students, where each student had an id of 1 to 10, how would I do that? Ideally, I'd like to do something like:

for(int i = 0; i < 10; i++){
Student i;
}
6.setName(fwhofdih);

But obviously that doesn't work. Its clear I'm new to all this. Any ideas on how I can do this? Thanks!

you could make a vector of students, or an array, if you wanted.

I'm trying to do it using objects, if at all possible. Would i put the student object into the vector?

[ultifinitus]

You would put instances of the Student class into the vector. Like so:

 vector<Student*> studpoints;

 studpoints.push_back(new Student(constructor));

 //dont forget to delete your newly allocated space the following function will do what you need, thank

   template <class C> void FreeClear( C & cntr ) {
    for ( typename C::iterator it = cntr.begin(); 
              it != cntr.end(); ++it ) {
        delete * it;
    }
    cntr.clear();
   }

note: this is using pointers to students not student objects.

Like this?

class Student
{
 private:
  int id;
  ... //other fields

 public:
  Student(int sid) {
    id = sid; //assign the id in the constructor
  }

  //create a method to get the student's id since the id field is private (hidden outside this class)
  int getID() {
    return id;
  }
  ... //other methods
};

//main function
int main() {
  Student roster[10]; //make a place to hold your students
  for( int id = 0; id < 10; id++ )
    roster[id] = Student(id); //create a Student with id id and store it into the roster at index id
  ... //do stuff with roster
}

Let me know if you have any questions.

I got it figured out, thank you all very much! I appreciate it.
