Adatfajták

Adatfajták, often translated as "data types," refers to the classification of data based on its characteristics and the operations that can be performed on it. This classification is fundamental in computer science and programming, as it dictates how data is stored, processed, and interpreted by a system.

In programming, data types are typically categorized into primitive types and composite types. Primitive data types are the most basic building blocks and include numerical types like integers (whole numbers) and floating-point numbers (numbers with decimal points), as well as boolean types (representing true or false values) and character types (representing single letters or symbols). Composite data types are constructed from primitive types and can include structures like arrays (ordered collections of elements of the same type), strings (sequences of characters), objects (instances of classes that bundle data and methods), and more complex data structures like lists or trees.

The specific set of available data types can vary between programming languages, but the underlying principle remains the same: defining the nature of information. Choosing the correct data type is crucial for efficient memory usage, accurate calculations, and preventing runtime errors. For instance, using an integer type for a value that might have decimal places would lead to data loss, while using a character type for a large number would be impossible. Understanding data types is a cornerstone of effective programming and data management.
