In the future steps, we will work with multiple arrays simultaneously. It can be a bit painful to fill them manually. Let’s write the program, which will fill the array with random values. To generate a random number, you can use the function `rand()`:

Too large, isn’t it? To set restrictions on the range in which you want to get a number, use the symbol `%`. For instance, the following code will print a random number **less than 10**:

You can also set the start of the required range. Just add `+`. The following program will write the random number in the range of **10 to 20**:

```
int a = rand() % 20 + 10;
cout << a;
```

Now we know how to get the random value. Let’s fill the array with random numbers **from 1 to 20**!

for (int i = 0; i < 5; i++){
&nbsp;&nbsp;&nbsp;&nbsp;numbers[i] = rand() % 20 + 1;
&nbsp;&nbsp;&nbsp;&nbsp;cout << numbers[i] << " ";
}

Random is often used in game development. Let’s play!

If you want to improve your skills in C++ and already have basic knowledge of this popular programming language, then this course is for you. The next level of C++ training includes basic concepts of memory and functions in C++, defining and implementing references, pointers, and arrays. Discover standard libraries, useful topics, and dynamic memory with practical examples.

In this section, you will repeat datatypes and arrays, discovering the memory behind them.

Here you will learn what pointers and references are, where they can be used, and the difference between them.

In this section, you will explore dynamic memory features and how to apply them.

In the final section of our intermediate course, you will learn the basics of functions and then write some functions by yourself!
