Why did we go deep into arrays while learning pointers? The fact is that the array’s name is a pointer to its first element.

We can get the address of the first element of the array by its name or by declaring the pointer:

int arr[5]{1, 2, 3, 4, 5};
int *p = &arr[0];

cout << p << endl;
cout << arr << endl;

In other words, indexing is equivalent to adding (or substructing) to the pointer:

cout << *(p+2) << endl;   // equivalent to arr[2]
cout << *(arr+2) << endl; // equivalent to arr[2]

The `for` loop we used to go through the arrays can also be used with pointers by adding 1 on each step, but we will use these feature pointers in work with functions and dynamic memory in the following sections.

Which of the following statements can be used to get the second element of the array x?

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!
