Learn C++ for free with this interactive course, and get a handle on one of the most popular programming languages in the world.

You'll start with a simple hello world program and proceed to cover core concepts such as conditional statements, loops, and functions in C++, before moving on to more advanced topics like inheritance, classes, and templates, along with much more.

By the time you're done, you'll be an intermediate level C++ developer, ready to take on your own projects.

What is the output of the code below?
``` C++
#include <iostream>
using namespace std;

class Temporary {};
 
int main()
{
 cout << sizeof(Temporary);
 return 0;
}
```

What is the output of the code below?
<pre><code class="language-C++">#include &lt;iostream&gt;
using namespace std;

class Temporary {};
 
int main()
{
 cout &lt;&lt; sizeof(Temporary);
 return 0;
}
</code></pre>

What is the output of the code below?

```C++
#include <iostream>
using namespace std;

class Score {
 int x; 
};
int main()
{
 Score sc;
 cout << sc.x;
 return 0;
}
```

What is the output of the code below?
<pre><code class="language-C++">#include &lt;iostream&gt;
using namespace std;

class Score {
 int x; 
};
int main()
{
 Score sc;
 cout &lt;&lt; sc.x;
 return 0;
}

All objects of a class share all data members, private and public, of a class

Objects of a class do not share members and every object has its own copy

Objects of a class do not have access to any members, public or private

A member function can always access the data in:

A member function can always access the data in:

Virtual functions can be overridden in derived class with the same decalaration

Virtual functions enable polymorphism in a inheritance hierarchy

Virtual function is called according to the actual type of the object referred to

Which of the following is true about virtual functions?

Which of the following is true about virtual functions?

What is the output of the following program:
```C++
#include <iostream>
using namespace std;

class Parent
{
public:
 virtual void view() { cout<<" In Parent \n"; }
};
 
class Child: public Parent
{
public:
 void view() { cout<<"In Child \n"; }
};
 
int main()
{
 Parent *p = new Child;
 p->view();
 
 Parent &pr = *p;
 pr.view();
 
 return 0;
}

```

What is the output of the following program:
<pre><code class="language-C++">#include &lt;iostream&gt;
using namespace std;

class Parent
{
public:
 virtual void view() { cout&lt;&lt;&quot; In Parent \n&quot;; }
};
 
class Child: public Parent
{
public:
 void view() { cout&lt;&lt;&quot;In Child \n&quot;; }
};
 
int main()
{
 Parent *p = new Child;
 p-&gt;view();
 
 Parent &amp;pr = *p;
 pr.view();
 
 return 0;
}
