In the previous lessons, we learnt about variables and their usage. In programming languages, these variables can be assigned values of different types. These include integers, decimal numbers, sequence of alphabetical letters, booleans (true or false) among several others. Programming languages not only offer these data types, but also allow programmers to perform various operations on them. In this lesson, we will focus on the data type called string, and the operations that are defined on strings.
