you use it when you dont know the size of the array it could be when a user inputs a word and you split it inside an array and reverse it using a for loop you would never know how long that word is unless you use length.

Not all the containers store data in contiguous memory allocation. If you have a simple array it's all fine . But consider std::list for example..

because you can pass a function when the array is the right length, which doesn't have to be to print the size. Example: int test[6] if (test.length < 5) { doSomething(); }

here is a question: what if you need to count the user’s input? you can’t know what the user will enter so you need a function that will count it for you. it is a great function for other purposes as well, for example, counting the length of items in an array or dictionary, etc.
