There are many types of numbers that we can use for different purposes. For now, let's have a look at int and double!
Huh! Integers, or int-type variables, only store whole numbers and doubles, and double-type variables, allow us to use decimal places.
Psst: with std::endl, we can add a line break in the console.
As we use int for whole numbers, wouldn't we lose the decimal places of 9.12345 that way?
