Why when we write like this "do or " it count 5 letter include ?
Can you explain it? And show how to show "do or" like this include 4letter in it.

Answer 1

In the his example you can see how to remove all the spaces in a string, but why do we want to remove spaces?

To answer your and my question:
Strings are basically an array of Characters, everything that takes up space like a comma, fullstop, number, letter or even a space takes up character space, so when you get the length of a string it basically see how many characters are present. This means that you can control how many characters are in a string.
