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.

Learn C++ from Scratch

Signifies the start of a preprocessor command

Allows names defined in this field to be used without their prefix

Allows a programmer to include functionality without having to cut and paste

What is the purpose of 
```
using namespace std; 
```

What is the purpose of
<pre><code>using namespace std; 
</code></pre>

The `int main` function is called by operating system when program is executed

The <code>int main</code> function is called by operating system when program is executed

A block of code is defined with the `( )` tokens

A block of code is defined with the <code>( )</code> tokens

`cout` cannot be used without the prefix `std`.

`int main()` is actually written as `int main {}`.

`include{iostream}` is written as `include<iostream>`

What is wrong with the following code:
```cpp
#include (iostream)
using namespace std;

int main() 
 cout << "Hello World!";
 return 0;
```

What is wrong with the following code:
<pre><code class="language-cpp">#include (iostream)
using namespace std;

int main() 
 cout &lt;&lt; &quot;Hello World!&quot;;
 return 0;
</code></pre>

`return 0;` should be `return "Hello World"`

The semicolon with `using namespace std` is missing.

The semicolon after `include<iostream>` is unnecessary.

What is wrong with the following code:
```cpp
#include <iostream>;
using namespace std

int main() {
 cout << "Hello World!"
 return 0;
}
```

What is wrong with the following code:
<pre><code class="language-cpp">#include &lt;iostream&gt;;
using namespace std

int main() {
 cout &lt;&lt; &quot;Hello World!&quot;
 return 0;
}
</code></pre>
