Calling custom objects whose names contain numbers in Objective-c

Question

I have declared custom objects in Objective-c project:

Student* student1 = [[Student alloc]init];
Student* student2 = [[Student alloc]init];
Student* student3 = [[Student alloc]init];
Student* student4 = [[Student alloc]init];
Student* student5 = [[Student alloc]init];
Student* student6 = [[Student alloc]init];

How can I call them in cycle

for (int i=1; i<=6; i++)
{
}   ?

You should be using an array for this – Hamish Jun 12 '16 at 09:58 — Hamish, Jun 12 '16 at 09:58
**You don't!** Use an array. – luk2302 Jun 12 '16 at 09:58 — luk2302, Jun 12 '16 at 09:58

You can't directly do that. You could use an array (either C-style or an NSArray) and then iterate over that (using zero-based indexes or a for-in loop).

For example:

NSArray* students = @[ [[Student alloc] init],
                       [[Student alloc] init],
                       [[Student alloc] init],
                       [[Student alloc] init],
                       [[Student alloc] init],
                       [[Student alloc] init],
                     ];
for (int i = 0; i < students.count; i++)
{
    Student* student = students[i];
    // Do something with student
}
// Or:
for (Student* student in students)
{
    // Do something with student
}
