bookLoops 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++) { &nbsp;&nbsp;&nbsp;&nbsp; cout << numbers[i] << " "; }
copy

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++) { &nbsp;&nbsp;&nbsp;&nbsp; numbers[i] = i; &nbsp;&nbsp;&nbsp;&nbsp; cout << numbers[i] << " "; }
copy
question mark

Choose the for loop to go though the array of 6 elements.
