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:

Single Dimensional Array
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.

#include <iostream>
using namespace std;
int main()
{
 int arr[5]={10, 0, 20, 0, 30};  //creating and initializing array  
        //traversing array  
        for (int i = 0; i < 5; i++)  
        {  
            cout<<arr[i]<<"\n";  
        }  
}

Output:/p>

C++ Array Example: Traversal using foreach loop

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

#include <iostream>
using namespace std;
int main()
{
 int arr[5]={10, 0, 20, 0, 30}; //creating and initializing array  
        //traversing array  
       for (int i: arr)   
        {  
            cout<<i<<"\n";  
        }  
}
