Sizeof
"Sizeof" is a word that tells us how big something is. Imagine you have a toy car and you want to know how big it is. You could say "What is the size of this toy car?" to find out.
In computer programming, the word "sizeof" works the same way. It tells us how much space something takes up in the computer's memory. Just like your toy car takes up space in your toy box, things in a computer take up space in the computer's memory.
Let's say you have a piece of information, like the number 5. You might think it's a small number, but in the computer's memory, it actually takes up a certain amount of space. The sizeof function can tell us exactly how much space it takes up.
This can be really important for programmers because they need to make sure they have enough memory available for all the things they want their program to do. By using the sizeof function, they can figure out how much space different pieces of information take up and make sure they have enough memory to store them all.
