délimiteurs

Délimiteurs are characters or sequences of characters used to mark the boundaries between distinct pieces of data or segments of text. They are fundamental in various fields, including computer science, linguistics, and everyday writing. In computing, delimiters are crucial for parsing data structures, separating elements in files, and defining the structure of commands. For example, a comma is often used as a delimiter in comma-separated values (CSV) files to distinguish between different data fields within a row. Similarly, spaces are common delimiters that separate words in a sentence.

In programming, delimiters play a vital role in defining the scope of code blocks, such as parentheses () and curly braces {}. They also mark the end of statements or queries. The choice of delimiter depends on the context and the data being processed. For instance, quotation marks (" " or ' ') are used to enclose strings, indicating that the characters within them should be treated as literal text rather than code or commands. Other common delimiters include semicolons (;), colons (:), and vertical bars (|). Understanding and correctly using delimiters is essential for accurate data interpretation and program execution. Their absence or misuse can lead to errors and misinterpretations of information.
