.length()

The .length() method returns the length of the given string in terms of bytes. It functions exactly like the .size() method but follows a more intuitive terminology (i.e., “the length of a string” rather than “the size of a string”). However, both methods yield the same result.

string.length();

The string must be defined with std::string prior to using with the .length() method.

In the example below, .length() is called on the snack string:
