C++ String Length

In C++, you can measure the number of characters in a string using the length() function. This comes in handy when working with text-based data, as it lets you evaluate the size of a string.

Getting the Length of a String

The length() function is used to determine the number of characters in a string, including spaces, symbols, and punctuation.

Example

C++

Output: This outputs the length of the text “Kawasaki Ninja ZX-10R”, including spaces between words.

Using the size() Function

C++ also provides the size() function, which works exactly the same as length(). Both are interchangeable, so you can use whichever feels more natural to you.
