részkarakterláncát

A részkarakterláncát is a Hungarian term that translates to "substring" in English. In computer science, a substring is a contiguous sequence of characters within a string. For example, in the string "programming," "program," "gram," and "ming" are all substrings. The concept of substrings is fundamental in string manipulation and is used in a wide variety of algorithms and programming tasks.

Operations involving substrings are common in many programming languages. These operations include finding substrings, extracting substrings, and comparing substrings. For instance, a programmer might need to find all occurrences of a specific substring within a larger text, or extract a portion of a string to use elsewhere in their code. The length of a substring can range from zero (an empty string) up to the length of the original string itself.

The term "részkarakterláncát" emphasizes that it is a part or a segment of a larger character sequence, or string. This concept is crucial for tasks such as pattern matching, text searching, data validation, and parsing. Understanding substrings is a foundational skill for anyone working with text data in programming.
