week 4

I had many problems in my lab. I think the reason is I did not do very well in 108. Therefore, I think I need to catch up in 148 because the mid-term is coming soon T T

Week3(Object-Oriented Programming)

Object-oriented programming  languages focus on creating objects  that contain data and  It let us to save time to reduce repetition and we can manipulate our program as we like. we make the data structure both the data and the functions that how we can make use of them. The methods can save programmers' time and let us reuse it again and again. Moreover, we can make  connection between old and new objects. For example, the subclass and the parent class, we can always use some methods from the parent class. And it insures more accurate coding through a  data analysis.
