Mastering Blockchain Programming with Solidity

Using arrays in Solidity

In Solidity, arrays can be fixed size or dynamic size. We have already seen in the previous sections, Fixed size byte arrays and Dynamically sized byte, arrays of this chapter that bytes and string are special types of array.

You can set the visibility of an array to public and have Solidity create a getter function for it automatically. As you can see in the following ArraysExample contract, the owners array is set to public.
