This tutorial focuses on:
- Creating an array
- Adding values to an array
- Accessing an arrays elements
- Modifying an arrays elements
Creating an array
Creating an array this way, you can add as many values as you want to it. Alternatively, you can specify an array to be of a particular size.
In the above example, an array named "colors" that can store 10 elements is created.
Adding values to an array
Once you create an array, you can add values to it by specifying the array name, an index in the array and a value to be placed in that index.
NOTE: Array indexes start at 0. So the 1st element of an array would be at index 0, the 2nd element at index 1, the 3rd element at index 2 and so on.
Another way to assign values to an array involves doing so during the array's initialization.
Accessing an arrays elements
To access an arrays elements, refer to the array with the appropriate index number in brackets.
Modifying an arrays elements
To modify an arrays elements, refer to the array with the appropriate index number in brackets of the value you want to change and set it to the new value.
