Foreign IOS written questions!

1, pretreatment constants # define statement to indicate how many seconds
year2, write a "standard" macro MIN, this macro input two parameters and returns the smaller one
3, obj-c or without multiple inheritance?
How to achieve the4, @ protocol to explain the role
5, agents, notice the difference? Where the use of

Code:
1, Define a node structure for a single linke list, as saving the mode can only hold single int value

Implement the list insertion function define as void Insert (ref Node headNode, int insertValue), Assuming the list is in ascending order and it hold single int value only, where headNode points to the begining of the list, and insertValue is the int value to insert?
