C++ Arrays

Like other programming languages, array in C++ is a group of similar types of elements that have contiguous memory location.

In C++ std::array is a container that encapsulates fixed size arrays. In C++, array index starts from 0. We can store only fixed set of elements in C++ array.

Advantages of C++ Array

• Code Optimization (less code)
• Random Access
• Easy to traverse data
• Easy to manipulate data
• Easy to sort data etc.

Disadvantages of C++ Array

• Fixed size

C++ Array Types

There are 2 types of arrays in C++ programming:

1. Single Dimensional Array
2. Multidimensional Array

C++ Single Dimensional Array

Let’s see a simple example of C++ array, where we are going to create, initialize and traverse array.

Output:/p>

10 0 20 0 30 

C++ Array Example: Traversal using foreach loop

We can also traverse the array elements using foreach loop. It returns array element one by one.

Output:

10 20 30 40 50
