merkkijonos

Merkkijono, often translated as "string" in English, is a fundamental data type in many programming languages. It represents a sequence of characters. These characters can include letters, numbers, symbols, and whitespace. Strings are typically enclosed in quotation marks, either single (') or double (").

The length of a string is determined by the number of characters it contains. For example, the string "hello" has a length of 5. Operations commonly performed on strings include concatenation, which involves joining two or more strings together, and searching for specific characters or substrings within the string. Many programming languages provide built-in functions or methods to manipulate strings, such as finding the length, extracting a portion of the string (substring), converting to uppercase or lowercase, and replacing characters.

Strings are used extensively in programming for tasks like storing text, user input, file names, and communication protocols. Their ability to represent textual data makes them a cornerstone of software development for a wide variety of applications. The specific implementation and available operations for merkkijono can vary between different programming languages, but the core concept of a sequence of characters remains consistent.
