Thank you for the opportunity to help you with your question!
An example of array is when it comes to c programming whereby it is used to store a collection of data
The advantages are that they use reference type, they are useful too when you are working with sequences of the same kind of data, used to represent multiple data items of same type by using only single name . The disadvantages is that sometimes it is not easy at all to operate with many index arrays, it causes unstable behavior of operating system because most of the time it uses a reference mechanisms.
Please let me know if you need any clarification. I'm always happy to answer your questions.
