Loops in Arrays

Initialize the array declaring every time the single element can take a lot of your code. To go through the array you can use for loops. Let’s print each element of the array using loops:


              1234
            
int numbers[5] = {1, 2, 3, 4, 5};
for (int i = 0; i <= 4; i++) {
    cout << numbers[i] << " ";
}

In this code, the for loop goes through each element by its index and print in such a way the whole array.

The last index of the array is 4 since we have 5 elements. Keep in mind that the first element’s index is 0 that’s why the for loop initialized the variable i to 0.

We can also define each element in the loops (for example, by its index):


              12345
            
int numbers[5];
for (int i = 0; i <= 4; i++) {
    numbers[i] = i;
    cout << numbers[i] << " ";
}

Tarea

Print each element of the array with its index.

Define the array.
Use for loop to go through array.
In output define the element and index in the gaps.
