Character String Functions
See also: Comparison of programming languages (string functions)String functions are used to manipulate a string or change or edit the contents of a string. They also are used to query information about a string. They are usually used within the context of a computer programming language.
The most basic example of a string function is the length(string) function, which returns the length of a string (not counting any terminator characters or any of the string's internal structural information) and does not modify the string. For example, length("hello world") returns 11.
There are many string functions that exist in other languages with similar or exactly the same syntax or parameters. For example, in many languages, the length function is usually represented as len(string). Even though string functions are very useful to a computer programmer, a computer programmer using these functions should be mindful that a string function in one language could in another language behave differently or have a similar or completely different function name, parameters, syntax, and results.

Famous quotes containing the words character, string and/or functions:
“A faithful lover is a character greatly out of date, and rarely now used but to adorn some romantic novel, or for a flourish on the stage. He passes now for a man of little merit, or one who knows nothing of the world.”
—Anonymous, U.S. women’s magazine contributor. Weekly Visitor or Ladies Miscellany, p. 20 (April 1803)
“First you find a little thread, a little thread leads you to a string, and the string leads you to a rope. And from the rope you hang by the ... neck.”
—A.I. (Albert Isaac)
“When Western people train the mind, the focus is generally on the left hemisphere of the cortex, which is the portion of the brain that is concerned with words and numbers. We enhance the logical, bounded, linear functions of the mind. In the East, exercises of this sort are for the purpose of getting in tune with the unconscious—to get rid of boundaries, not to create them.”
—Edward T. Hall (b. 1914)
