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.

Which operator can be used to dereference a pointer, `p`?

Which operator can be used to dereference a pointer, <code>p</code>?

Pointers allows us to point to objects in:

Pointers allows us to point to objects in:

What will be the value of `*p` at the end of this code?
``` C++
int *p;
int var = 10;
p = &var;
*p = 15;
var = 20;
```

What will be the value of <code>*p</code> at the end of this code?
<pre><code class="language-C++">int *p;
int var = 10;
p = &amp;var;
*p = 15;
var = 20;
</code></pre>

What will be the value of `*x` and `y` after the `foo` function call in the code below?
```C++
void foo(int *p, int q){
  *p = *p + q;
  q = *p * q;
}

int main(){
  int *x = new int(5);
  int y = 7;
  foo(x, y);
}
```

What will be the value of <code>*x</code> and <code>y</code> after the <code>foo</code> function call in the code below?
<pre><code class="language-C++">void foo(int *p, int q){
 *p = *p + q;
 q = *p * q;
}

int main(){
 int *x = new int(5);
 int y = 7;
 foo(x, y);
}
</code></pre>
