Adattípusokkal, commonly translated as "data types," refers to the classification of data in computer programming. These classifications determine the kind of value a variable can hold and the operations that can be performed on it. Understanding data types is fundamental to writing correct and efficient code.

In most programming languages, common data types include integers (whole numbers), floating-point numbers (numbers with decimal points), characters (single letters or symbols), and booleans (true or false values). Integers can be further divided into signed and unsigned, and different sizes like short, int, and long, affecting the range of values they can represent. Floating-point types also have variations like float and double, differing in precision.

Beyond these basic types, many languages offer more complex data structures. These can include strings (sequences of characters), arrays (ordered collections of elements of the same type), and objects (instances of classes that encapsulate data and behavior). Some languages also support user-defined data types, allowing programmers to create their own custom classifications tailored to specific application needs. The choice of an appropriate data type impacts memory usage, processing speed, and the potential for errors. For instance, using an integer type for a value that requires decimal precision would lead to data loss. Correctly utilizing data types is a cornerstone of robust software development.
