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?

```C++
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 class="language-C++">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;
</code></pre>

If originally `x=10`, what is the value of `x` after:
```cpp
x += 10
```

If originally <code>x=10</code>, what is the value of <code>x</code> after:
<pre><code class="language-cpp">x += 10
</code></pre>

What is the answer to the following statement:

```
1 + 3 * 3 % (15 - 6)
```

What is the answer to the following statement:
<pre><code>1 + 3 * 3 % (15 - 6)
</code></pre>

What is the value of the answer in the following C++ program?
```cpp
int x=4
int answer = pow(x,2);
```

What is the value of the answer in the following C++ program?
<pre><code class="language-cpp">int x=4
int answer = pow(x,2);
</code></pre>

```cpp
char uppercase = 'D';
char lowercase = static_cast<char>(static_cast<int>(uppercase) + 32);
```

```cpp
char uppercase = 'D';
char lowercase = static_cast<char>(static_cast<int>(uppercase) - 32);
```

```cpp
char uppercase = 'D';
char lowercase = uppercase;
```

```cpp
char uppercase = 'D';
char lowercase = uppercase + 1;
```

How would you convert the character `D` to its lowercase equivalent?
