Literals, in computer programming, refer to values that are directly expressed in code. These values can be in the form of numbers, strings, and boolean expressions. However, there are other terms that can also be used to describe literals. For instance, in some programming languages, literals can be called constants. The term "values" can also be used interchangeably with literals. In addition, the term "literal values" can also be used to refer to the specific values that are being expressed in the code. Lastly, in certain programming languages, literals are referred to as atoms. Despite the different terminologies used for literals, their function remains the same - to provide clarity and immediately convey information to the computer.
