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.
