Object-oriented programming (OOP) has been around for decades. If you have a basic understanding of C++ and are interested in leveling up your skills, this class will help you do just that. 

Starting with an overview of the basics, you’ll dive into understanding the time-honored technique for implementing complex applications using user-defined classes. Followed up by discussing classes and objects, and then building up to the high-level topics including inheritance and polymorphism. 

Throughout the course, you’ll be fully immersed in OOP for C++, with illustrations, exercises, quizzes, and hands-on challenges every step of the way. You’ll walk away with an understanding of classes and objects behavior and be able to easily create simple, efficient, reusable and secure code.

The attributes of a class can be divided into the following two parts:

What is the output of the code below?
``` C++
class Score {
 int num;
 public:
 Score(){
 num = 0;
 }
 Score(int n){
 num = n;
 }
 int getNum(){
 return num;
 }
};

int main() {
 Score sc(5);
 cout << sc.num;
}

```

What is the output of the code below?
<pre><code class="language-C++">class Score {
 int num;
 public:
 Score(){
 num = 0;
 }
 Score(int n){
 num = n;
 }
 int getNum(){
 return num;
 }
};

int main() {
 Score sc(5);
 cout &lt;&lt; sc.num;
}

</code></pre>

The scope resolution operator can be used to define member functions outside the class definition in the following syntax:

``` C++
returntype memberFunction::className
```
