    Abstraction: Implementation Hiding - Simplify Reality: Focus only on what something does, not how it does it. Encapsulation: Information Hiding - Properties and Methods information are put together and their data is hidden. Inheritance: Inherit Methods and Properties - A class inherits methods and properties from parent class. Polymorphism: Inherited method can do its own thing A subclass from a superclass can implement inherited methods in its own ways.

    I think it is better to describe abstraction as ignoring some information rather than hiding it :)KD

  • @ComputerScienceLessons
    @ComputerScienceLessons10 күн бұрын

    Remember that the most significant place value is negative. So the leftmost 1 in 10.01 has a place value of -2. The rightmost 1 has a place value of 0.25. We can therefore calculate that -2 + 0.25 = -1.75 Take a look at my video on Two's Complement if you are unsure of this :)KD

    So I have a question, and forgive my ignorance (I am learning as I go and not in college). So if Mia for example, has an ASCII code of 77+105+97 = 279, dividing that (279 Mod 11 = 25 on my calculator). However in MDN docs it comes to 4 in the example, the correct answer. Just trying to figure out how we got to 4 and maybe using the calculator is the wrong thing?

  • @ComputerScienceLessons
    @ComputerScienceLessons16 күн бұрын

    Hi. I'm guessing you pressed the wrong button. Modulus is the remainder after whole number division. So for example 17 mod 3 = 2. (three goes into seventeen five times with two remaining) . 279 mod 11 = 4 (eleven goes into 279 twenty five times with four remaining). Try typing 279 mod 11 into Google. I hope this helps :)KD
