Data Types in C - GeeksforGeeks
Different data types also have different ranges up to which can vary from compiler to compiler. If you want to know more about ranges refer to this Ranges of Datatypes in C. Note: The long, short, signed and unsigned are datatype modifier that can be used with some primitive data types to change the size or length of the datatype.

C Data Types
In this tutorial, we will focus on the most basic ones: There are different format specifiers for each data type. Here are some of them: Note: It is important that you use the correct format specifier for the specified data type.

Difference Between Primitive and Non-Primitive Data Structure
Non-primitive data structures (like arrays, strings, lists, stacks, trees, graphs) store multiple values or complex data, support operations (insert, delete, search), and are stored in heap memory.

r/learnprogramming on Reddit: Why do data types like "char" , "int" or "long" are called primitive, when they are all made up of binary? Technically, isn't all non-binary data "non primitive / composite"?
May 4, 2022 -
All integers are made up of binary. And char is made up of an integer, which is made up of binary, so it's technically a "higher order data type" than it's int and long primitive relatives.
It sounds nitpicky, but isn't everything beyond a boolean or a group of booleans a composite data type? Shouldn't booleans be the only primitive type?

at least for java primitives are the types which are not objects. this means their variables are an actual value, instead of a reference to an object Shouldn't booleans be the only primitive type? most booleans are actually a byte since single bit addressing is slow

you're right that it is all binary eventually. Data types are are primitive usually fit into a number of categories. A primitive data type comes with the language and is idiomatic for the language. A primitive data type should be able to be expressed in the language using a limited amount of memory. A primitive data type has no additional methods attached to it (usually) The primitive data types are basically just data types that have been defined over the decade and they are considered so fundamental to programming and expressions in general with a language that nearly every language comes with a set of primitives you can use. Additionally, these primitives are fundamental and well documented to such a severity that there is a standardized way to handle them in memory. For example, characters and strings are typically handled with the ASCII way: https://erg.abdn.ac.uk/users/gorry/eg2069/ascii.html However, the whole point of programming is we want to make NEW things. We can easily define new data types. Infact whenever you define anything in any programming language you are de-facto making a new data type. For example class car = { doors = 4; color = "red"; wheels = 4; } When you define a new class, or even a new fuction. You're literally saying there is a new data type "car" and it has these properties and has these methods. These properties and methods is how it interacts with the rest of the language. any new data type typically is defined with primitives to keep track of it's properties and sometimes it's properties can even be other classes you've defined like this: class door { windows = 2; automatic_windows = true; } class car = { doors = [new door(), new door(), new door(), new door()]; color = "red"; wheels = 4; } These are new data types which we are creating, and languages that require typing syntax typically AUTOMATICALLY assume your classes are also types. So that's the easiest way to distinquish primitives from non-primitives. The primitives are already in the language when you kick up a new environment. Most primitives also are highly optimized and therefore are very performant. As you could imagine, a class/data type we define ourselves could be fairly bloated and significantly less performant than something as performant as an integer. It's important to note that there is a distinction between a class and a data type. These two things are not the same thing, but every class is ALSO a data type in addition to it's other capabilities.

The answer is no, and for 2 reasons.
- The notion of primitive types in Java exists by opposition to object types. This has no sense in C which is not an object language.
- C intends to be as efficient as possible on any architecture, from 16 or even 8 bits microcontrollers to 64 bits platforms. For that reason the
inttype is generally chosen as the natural type for the architecture provided it contains at least 16 bits. On the other hand, Jave targets maximum portability and fixes the size of all its types.
So even if the list on Wikipedia looks large, it is (unfortunately...) accurate.

C appears to have many, many types, but what if any are considered primitive types.
The Java term "primitive type" distinguishes from reference types. C has no direct analog of Java's reference types, so no need to draw such a distinction.
C does, however, define several categories of types, and among those, the basic types are a reasonably good analogue of Java's primitive types. This category comprises char, the signed and unsigned integer types, and the floating[-point] types. It is ultimately from these, the enumerated types, and type void that all other types are derived, including array types, structure and union types, pointer types, atomic types, and function types.
The basic types can include implementation-defined types, and therefore cannot be exhaustively listed, but those defined by the language spec are:
char
The standard signed integer types
signed char, short int, int, long int, long long int
The standard unsigned integer types
_Bool, unsigned char, unsigned short int, unsigned int, unsigned long int, unsigned long long int
The real floating types
float, double, long double
The complex types
float _Complex, double _Complex, long double _Complex
This is covered in section 6.2.5 of the language spec.
It should be noted that whereas Java specifies the the size and representation of its primitive types, C leaves some of those details of its basic types to implementations, placing constraints on their ranges of representable values and other properties without specifying exact details.
C appears to have many, many types
C has an unbounded number of types, as it provides for types to be derived from other types. The same applies to Java. Ignoring implementation-defined extension types, C has more than twice as many basic types as Java has primitive types, but that's still manageable, especially given the way they are organized.
However, C also has a mechanism for defining type aliases, and a whole family of standard type aliases, and these can make it appear that there are more types than really there are.

Serve as the building blocks for more complex data structures. Non-primitive data structures, on the other hand, are more complex forms of data structures that are derived from primitive data types.
