Then you went ahead and learnt about the strings and characters data types. There you learned how to store multiple characters as strings and the concept of string concatenation.

Then came arrays. There you learnt how to index the elements in an array and how to access elements of an array using these indices. You also learnt about boolean data types which can store true or false values only. Last but not least, you learnt about various types of errors and how to make your code error free.
