FWIW, here's my code, tested with g++ 3.2 on a laptop running RH Linux 8.0. AFAIK it is standard C++ and should work on VC++ with no problems too (can someone verify this for me please, because I can only test it for myself on monday at work - thanks in advance).
Code:
#include <iostream>
using namespace std;
class Student {
public:
int x, y;
Student(int a, int b);
};
Student::Student(int a, int b) {
x = a; y = b;
}
int main(void) {
int num_students;
cout << "Enter # of students: ";
cin >> num_students;
Student *student = new Student[num_students](5, 3);
for (int i = 0; i < num_students; i++) {
cout << "Student #" << i+1 << ". " << student[i].x << ", " << student[i].y << endl;
}
delete [] student;
return 0;
}
Thanks for the vote of confidence 7stud

Aw shoot, guess I'd have to declare a constructor with no arguments to make it work with VC++ 6.0. Guess this should work then:
Code:
#include <iostream>
using namespace std;
class Student {
public:
int x, y;
Student();
Student(int a, int b);
};
Student::Student() {
x = 5; y = 3;
}
Student::Student(int a, int b) {
x = a; y = b;
}
int main(void) {
int num_students;
cout << "Enter # of students: ";
cin >> num_students;
Student *student = new Student[num_students];
for (int i = 0; i < num_students; i++) {
cout << "Student #" << i+1 << ". " << student[i].x << ", " << student[i].y << endl;
}
delete [] student;
return 0;
}
Thanks for testing it out

apologies accepted
 scorp, that is quite exactly what i meant. but, you will have to add Create(x,y) function to intialize x and y, and to retrieve the info from the user. you will also have to do it in your g++ version. what you have done there is to initalize ALL the x and y's with 3 and 5... i don't think that how it should be... anyway, i think we have covered this thread all around.
