Zusammenfassung von Objektmengen mit den darauf definierten Operationen
A data type is a classification system that tells a computer what kind of information it's dealing with—such as numbers, text, or true/false values—so it knows how to store and process that information correctly. Data types matter because using the right one makes programs work efficiently and helps prevent errors when the computer performs calculations or manipulates information.

geeksforgeeks.org →The term "data type" in software programming describes the kind of value a variable possesses and the kinds of mathematical, relational, or logical operations that can be performed on it without leading to an error. Numerous programming languages, for instance, utilize the data types string, integer, and floating point to represent text, whole numbers, and values with decimal points, respectively. An interpreter or compiler can determine how a programmer plans to use a given set of data by looking up its data type. Primitives are predefined data types that are independent of all other kinds and include basic values of particular attributes, like text or numeric values. They are the most fundamental type and are used as the foundation for more complex data types. Most computer languages probably employ some variation of these simple data types. Composite data types are made up of various primitive kinds that are typically supplied by the user. They are also referred to as user-defined or non-primitive data types. Composite types fall into four main categories: semi-structured (stores data as a set of relationships); multimedia (stores data as images, music, or videos); homogeneous (needs all values to be of the same data type); and tabular (stores data in tabular form). A user-defined data type (UDT) is a data type that derived from an existing data type. You can use other built-in types already available and create your own customized data types. Integer (int) represent numeric data type for numbers without fractions 300, 0 , -300 Floating Point (float) represent numeric data type for numbers with fractions 34.67, 56.99, -78.09 Character (char) represent single letter, digit, punctuation mark, symbol, or blank space a , 1, ! Boolean (bool) True or false values true- 1, false- 0 Date Date in the YYYY-MM-DD format (ISO 8601 syntax) 2024-01-01 Time Time in the hh:mm:ss format for the time of day, time since an event, or time interval between events 12:34:20 Datetime Date and time together in the YYYY-MM-DD hh:mm:ss format 2024 -01-01 12:34:20 cout using namespace std; int main() { double doubleValue = 54.7; int intValue; intValue = doubleValue; cout Take the machine's 32-bit quantity, for instance. It can be used to represent four ASCII characters, an int, or a floating point. In light of the situation, these interpretations might be accurate. For example, when using assembly, the programmer bears full responsibility for maintaining track of the data types. When a machine-level floating point addition is performed on a 32-bit number that actually represents an integer, the result is indeterminate, which means that the outcomes may vary from computer to computer. In Conclusion, Programmers can create dependable and efficient code by utilizing data types. Data types can help organizations manage their data more effectively, from collection to integration, in addition to helping programmers write more effective code. Data types are the basis of programming languages. There are various kind of data types available according to the various kind of data available. Data types are of 3 types. Primitive Data type: int, float, char, bool Composite Data Types: string, array, pointers User Defined Data Type

Formal bezeichnet ein Datentyp (vom englischen data type) oder eine Datenart in der Informatik die Zusammenfassung von Objektmengen mit den darauf definierten Operationen. Dabei werden durch den Datentyp des Datensatzes unter Verwendung einer sogenannten Signatur ausschließlich die Namen dieser Objekt- und Operationsmengen spezifiziert. Ein so spezifizierter Datentyp besitzt noch keine Semantik. Die weitaus häufiger verwendete, aber speziellere Bedeutung des Begriffs Datentyp stammt aus dem Umfeld der Programmiersprachen und bezeichnet die Zusammenfassung konkreter Wertebereiche und darauf definierter Operationen zu einer Einheit. Beispiele können Ganz- oder Kommazahlen, Zeichenketten oder auch komplexere Typen wie Datum/Zeit oder Objekte sein. Zur Unterscheidung wird für diese Datentypen in der Literatur auch der Begriff Konkreter Datentyp verwendet. Für eine Diskussion, wie Programmiersprachen mit Datentypen umgehen, siehe Typisierung. Der gedankliche Übergang von der formalen Definition zu der im Umfeld von Programmiersprachen verwendeten Definition konkreter Datentypen geschieht dabei über die sukzessive Einführung einer Semantik zu den formal spezifizierten Namen der Objekt- und Operationsmengen.Die Konkretisierung der Operationsmenge führt zu Abstrakten Datentypen beziehungsweise Algebraischen Strukturen.Mit der weiteren Konkretisierung der Objektmenge ergibt sich der Konkrete Datentyp.
