-(void) displayStudentInArray : (????) studentarray atIndex: (int) index {.....}

‘???’ are my problem. what do i write there? i ve no idea.

need help. i m new on objective c.

Answer 1

Rather than using C notation the array should be made like this:

NSArray *studentArray = [[NSArray alloc] initWithObjects: student1, student2, student2, ..., nil];

In which case the parameter type will be NSArray

-(void) displayStudentInArray : (NSArray *)studentarray atIndex: (int) index {.....}
