String length

Writing functions:

strlen(x)

Returns the length of the string in characters.

The strlen function plays an important role in programming, as it allows you to determine the length of a string. The length of a string is the number of characters contained in that string. This indicator is often used in various algorithms and tasks.

It is important to remember that the function returns only a numeric value - the length of the string. If we want to display the result on the screen, then we need to use another code, for example, the console output function.

Thus, the function that returns the length of a string plays an important role in programming and can be used to solve various tasks related to processing and analyzing text data.
