Loop Through Each Item of an Array in C++

For iterating through an array, we create a loop that iterates the same number of times as there are elements in the array. For that, we will create a loop variable that starts from 0 (as arrays in C++ are 0-indexed), increments by one in each iteration and goes till it is less than the size of the array.

We can use any loop of our choice. Here, we are using for loop

Syntax for Iterating Through an Array in C++

Below is the syntax of a basic for loop to traverse over an array.

for (lv; lv < size_of_array; lv++) {
        //body of loop
}

where,

• lv: It represents the loop variable.

In C++, an array is a data structure that stores elements of similar type in contiguous memory locations. We can access the elements of an array using array indexing. In this article, we will learn how to loop over an array in C++.

Example:

Input:
int arr[] = [1, 2, 3, 4, 5]

Output:
Array Elements: 1 2 3 4 5
