Hey there! Welcome to another conceptual post on geekstocode! In this post we will be learning about the Primitive and Non-Primitive Data Types in C++. These data types are the basics in C++ Programming Language. Thus, you will require them to work on the coding in this language. Also, this concept is essential for any level examination as it is a beginner level concept.
Hence, we have listed all the necessary details about this topic for your learning and understanding. Going through this post will help to make you aware of this concept so that you can use it in the future. Since it is the first step of studying a language, we hope you can read and understand the article easily.
Before getting into the article, make sure to check out our other conceptual and informative posts that will help boost your coding skills.
Hence, let’s not waste time and get right to it!
What are Data types?
In C++ Program language, we restrict the variables by the type of data they store. In other words, while declaring, these variables use data-type to restrict the type of data that they have to store.
Thus we use data types to tell the tell the variables the type of data it can store. Or, data types are the tools which instruct the variables about the type of data that they will store while working on any C++ Program.
Additionally, when we define a variable in C++, the compiler allocates some memory for that variable based on the data-type with which we declare this variable. Also, every data type requires a different amount of memory.
These data types define the type of data the variable holds. For example, an integer variable can only hold integer data, a float variable can only hold decimal data, etc.
In short, a data type specifies the type of data that a variable can store, such as integer, floating, character etc.
C++ Programming language has two types of Data Types. Namely, Primitive data types and Non-Primitive Data Types. In further sub topics we will learn them in detail.
Primitive Data Types
We define a primitive type as a data type where the values that it can represent have a very simple nature (a number, a character or a truth-value). You can consider the primitive types are the most basic building blocks for any programming language and the base for more complex data types. Thus, they serve a great purpose to our C++ Language programming.
In simple terms, we know and use these “data type” and “primitive data type” as interchangeable variables. Also, these primitive data types are predefined types of data, which are supported by the programming language. For instance, integer, character, and string are all primitive data types.
Non- Primitive Data types
Now, we move on to the next type of data in C++ Programming language, i.e the Non-Primitive data types.
One thing to remember about this data type is that the programming language does not define the Non-primitive data types. But the programmer creates them instead, pretty interesting, isn’t it? This means the programmer has full control over these data types and can use them according to their wishes.
Additionally, we sometimes call them “reference variables,” or “object references”. Since they reference a memory location, which stores the data. For example, arrays, structures, etc.
In other words, the non-primitive data types are the types that the programmer defines. Also, C++ classifies them further into linear and nonlinear data types.
The purpose of these linear data types is to store the data inside the memory in a sequence one after.
When you have to retrieve the data from the linear data structure. Then you have to just start from one place and you can find other data in a sequence.
Difference between primitive and non primitive data types
Since now you know the basics about the primitive and non primitive data types, let us move on to the next section.
The primitive and non primitive data types though have some similarities, but their differences are more. If we look through them closely, we would differentiate them more nicely so let us proceed.
The Primitive data type:
- You can take a primitive data type is one that fits the base architecture of the underlying computer. Such as int, float, and pointer, and all of the variations; thereof such as char short long unsigned float double and etc, are a primitive data type.
- The primitive data type is not a special data type with extra ordinary capabitities. Hence, they are only single values.
- Primitive data types are the following, for instance, byte, short, int, long, float, double, char etc.
- There is another concept linked to the Primitive data types, i.e the primitive data structures. Thus these primitive data structures include the integer reals, logic data character data pointer, and reference. Additionally, the machine level instruction directly operates upon primitive data types and data structures.
The Non-Primitive Data Type:
- A non-primitive data type is something else such as an array structure or class. Also, these are user defined types.
- Non primitive data types can also be referred to as the data type that is derived from primary data types.
- Also, we use the non-primitive data types to store the group of values.
- Examples of the non-primitive data types are Array, structure, union, link list, stacks, queue etc.
- The machine level instructions does not directly operate upon the non primitive data types.
Wrapping it up:
Thus, we have completed learning about the Premitive and Non-Primitive data types in C++ Programming Language. In this post we have covered all the important concepts related to this topic for your benefit. Though this is a theoretical concept, these data types are very essential in C++ Programing. Hence, you need them in your programs and for that you need to learn about them properly.
Going through this article will give you all the necessary details so you don’t have to search and learn pages together for this concept. Make sure to study it thoroughly and use them in your codes to know their usage thoroughly.
Most students neglect these basic topics and suffer later so make sure to not lose practice and touch with these beginner level topics.
With that, we take your leave. We will come back with more posts like these!
Stay tuned till then.
