Learn how binary numbers, bits, and bytes relate to primitive types and how numbers, booleans, and characters are stored in memory in different programming languages.
- If we need to store more than one character,…then we would have to store our data…in something called a string,…which is a data type composed of a sequence of characters.…Think of those happy birthday banners…that are strung together with a string.…That's what we're talking about here.…Each letter flag is a character…and the string literally ties them together…and groups them in a specific order.…Now strings are stored a little bit differently…than everything we've worked with so far,…so we'll come back to them.…So how exactly does an int, or a double,…or a boolean, or character relate…to ones and zeros in bits and bytes?…Well, each of these data types are a certain size,…or in other words, they each contain a specific number…of ones and zeros.…
We call a single one or zero a bit.…In fact, a boolean is represented with a single bit,…a single one or zero.…This is because a boolean is either a true or false value.…In this case, zero stands for false and one stands for true.…This is the only piece of information we need,…
