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 from the following C++ program?

```
 int a,b,sum,subtr;
 a=100;
 b=20;
 sum=a+b;
 subtr=a-b;
 
 cout << "sum is: "<< sum;
 cout << "subtr is: " << subtr;
```

What is the output from the following C++ program?
<pre><code> int a,b,sum,subtr;
 a=100;
 b=20;
 sum=a+b;
 subtr=a-b;
 
 cout &lt;&lt; &quot;sum is: &quot;&lt;&lt; sum;
 cout &lt;&lt; &quot;subtr is: &quot; &lt;&lt; subtr;
