stringmanipuláció

String manipulation refers to the process of altering, modifying, or processing sequences of characters, commonly known as strings. This is a fundamental operation in computer programming, essential for tasks ranging from data validation and text processing to web development and natural language processing.

Common string manipulation operations include concatenation, which involves joining two or more strings together. Another frequent operation is substring extraction, where a portion of a string is selected based on start and end positions or lengths. Functions for finding the length of a string are also standard.

String manipulation also encompasses methods for searching within a string for specific characters or sequences, such as finding the first or last occurrence of a substring. Replacement operations allow for substituting parts of a string with other characters or strings. Case conversion, such as converting a string to uppercase or lowercase, is another common manipulation.

Splitting a string into a list or array of smaller strings based on a delimiter is also a widely used technique. Conversely, joining an array of strings into a single string using a specified separator is also a part of string manipulation. These operations are typically implemented through built-in functions or methods provided by programming languages. Understanding and effectively utilizing string manipulation techniques is crucial for efficient and robust software development.
