#BASIC DATA TYPES AND OPERATIONS HOW TO#

Consider I am trying to store a phone number or I am trying to store an account number, such types of things we can store with the help of long integer type.ĭepending on the size of the data, we choose a particular datatype. To store such type of data, a very little integer is enough, so we can consider short data type. For example, department numbers are 10, 20, 30, etc. It depends on the data and also depends on the size of the data. If you want to store one integer value, one integer data type is enough. The basic advantages of classifying these many types of nothing but utilizing the memory more efficiently and increasing the performance. Why is the integer data type classified into six types? To better understand the integer data types, please look at the image below. So, one integer data type is again subdivided into 6 types. Same for int and long, i.e., signed int, unsigned int, signed long, and unsigned long. Integer Data Type in C Language:Īgain, Integer is divided into three types as follows.Īgain, the short data type is divided into two types, i.e., signed short and unsigned short. char: Represents single characters and requires 1 byte of memory.double: Used for double-precision floating-point numbers.float: Used for single-precision floating-point numbers.Size can vary based on the system but is typically 4 bytes on modern systems. Classification of Primitive Data Types in C Language:Īs we already discussed, the Primitive Data Types are classified into four following types. In this article, we will keep the focus on the Primitive Data Types. Note: We will discuss Derived, and User-defined Data Types later as Array, Function, Pointer, Structure, Union, etc. User-Defined Data Types: Structure, union, typedef, enum, etc., comes under user-defined data types.įor a better understanding, please look at the below diagram, which shows a high-level classification of C Language data types.Derived Data Types: Array, String, Pointer, etc., come under derived data types.All these are called primitive data types.

Primitive Data Types: Integer, character, float, void.

How much memory is required to store the data? How Many Types of Data Types are Available in the C Language?ĭata Types in C Language are classified into three types as follows.

What type of data is allowed to be stored?.

Simply, datatype represents two things about a variable. For a better understanding, please have a look at the following diagram. But can we store 12.34? The answer is No. Next, if we store 17, which is a positive integer, it is also allowed in the C language. So, what type of data is allowed once the variable is ready? Suppose I am storing -15, a negative integer number, so it is allowed. So, every variable gets memory allocation, and the integer variable occupies 2 bytes (or 4 bytes) of memory. We have already discussed that the memory address is a positive integer. Here, a gets memory allocation at some location. Suppose I am declaring a variable of type integer

The data type represents these two in any programming language. That means how much memory must be allocated and what data type can be stored. In the above variable declaration, a is the identifier, and int is the data type. If you look at the variable syntax, you will understand that the variable declaration consists of two parts, i.e., the data type, which is followed by the identifier, as follows. In the declaration of every variable, it is mandatory to specify its data type. We need the concept data types to store all these types of data in the program to perform business-required calculations and validations. In the real world, we have different types of data like integer, floating-point, character, string, etc.
