Two Questions That've Haunted Me Ever Since I Started C++

[DeanDemon]

These questions have haunted me ever since I started C++.

1.) What EXACTLY is object oriented programming, and what are the advantages of using it?

2.) What are some practical uses for C++, and why should I learn it?

If you can give me some good answers to these questions, you'll make my day.

1) OOP is making your code fit your problem rather than trying to fit your problem into the code. In C++, OOP involves writing classes which are like data types.
One example I've heard several times to demonstrate OOP is that of a bank. An object is just a thing or person. Tellers, customers, accounts, and money are all objects. Each teller can perform a deposit or withdrawl yet they all have different names and employee IDs. Every customer has information like a PIN number which would definitely be put in the private section of the class so that people couldn't see those passwords. Objects of a single class all share certain abilities yet can have different values assigned to them.
Think about the data types you already know like int. If num1 and num2 are declared as integers, you can do all the mathematical operations on either that you can do, and they can have different values.
I hope that helped. As for your second question, I'm not entirely sure. I'm a high school senior who's thinking about majoring in Comp Sci, and I'm worried that once I get to college I'll have to learn Java and I will have learned C++ for nothing.

I'm a Comp Sci Major now and we mainly use C++. I barely used Java at all, when you are doing things such as writing operating systems and such, java is not a very good option.

2.) answer: ANYTHING can be written in C++. simple as that. if you see it on your computer, it could have been written in C++, the lone exception being some low level bootstrap and bull**** code.
