A string is a sequence of characters enclosed in quotation marks. One of the functions that can be used with strings is the count function.

Syntax

(count svariable)

Parameter

This method accepts one parameter, svariable, which represents the string variable.

Return value

This method returns the number of characters in a string.

Example

(ns clojure.examples.hello
(:gen-class))
(defn example []
(println (count "Educative")))
(example)

Explanation

  • Line 3: We create a function, example.
  • Line 4: Inside the function example, we use the count method to count the number of characters in the "Educative" string. Next, we print the output using println.
  • Line 5: We call the example function we created.
