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:
1234int 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
ito0.
We can also define each element in the loops (for example, by its index):
12345int numbers[5]; for (int i = 0; i <= 4; i++) { numbers[i] = i; cout << numbers[i] << " "; }
