# cat() Function

Enhancing the output with descriptive text can greatly improve the **readability** and **user-friendliness** of the results. In R, the `cat()`

function serves this exact purpose.

With `cat()`

, you can combine **text**, **expressions**, and **variables** to construct a meaningful output. Each element you want to include in the output should be separated by a **comma**, and strings of text must be enclosed in **quotes** (either double `""`

or single `''`

). By default, `cat()`

separates each argument with a space.

Let's take a look at an example:

`cat("The result of integer division is", 10 %/% 3) cat("The remainder of the division is", 10 %% 3)`

This approach clearly enhances the output, providing context and clarity. When you call the `cat()`

function, it prints each message on a **new line** by default.

Reflecting on the task of calculating full days and remaining hours from `435`

hours, let's enhance the output format. The output should be structured as follows:

Remember to use **integer division** (`%/%`

) to determine the number of whole days and the **modulo operator** (`%%`

) for any remaining hours.
