i write this with four binary tree to store the contact list, where it store by name, number, email and address.
writing this stupid thing cost me a lots of time, because of the limitation in c. Plus hard to look for information of c programming, especially in binary tree. The concept was not hard, but to implement it, it's need a lots of understanding, to understand, time is needed...
More tired then the assessment before, but this is the only time i feel the success...
haha... cause this one is more challenging then previous one...
finally can enjoy a bit before the final exam is coming~ hehe

very sad to said that my sony a300 view finder and image sensor had some dust stuck on it, i try to clean it by those tools recommended by those photographer kaki, but the situation didn't get any better... sometimes it did make it better, but sometimes dont.
so i decide to send my a300 to service~ maybe the next time i went back la...
sad....
