And long and short affects the range of the values for any datatype.ДЇor example, signed int, unsigned int, short int, long int, etc. Similarly, there are modifiers in the C language, to make the primary data types more specific.ДЄs the name suggests, signed and unsigned are used to represent the signed(+ and -) and unsigned(only +) values for any data type. In the C language, there are 4 datatype modifiers, that are used along with the basic data types to categorize them further.ДЇor example, if you say, there is a playground, the other person will know that there is a playground, but you can be more specific and say, there is a Cricket playground or a Football playground, which makes it even more clear for the other person. Good Read: Understand what are Bits and BytesД«efore moving on to the range of values for these data types, there is one more important concept to learn, which is Datatype modifiers. The void data type means nothing, hence it doesn't have a size. The double data type can hold approximately 15 to 17 digits, before the decimal and after the decimal. In the 64 bits, 1 bit is for sign representation, 11 bits for the exponent, and the rest 52 bits are used for the mantissa.

It can store values that are double the size of what a float data type can store, hence it is called double.

The double datatype is 8 bytes or 64 bits in size. It is used for storing large values.ДЇloat is a faster data type as compared to double, because double data type works with very large values, hence it is slow. It is a single-precision data type that is used to hold decimal values.

The float datatype is 4 bytes or 32 bits in size. In simpler words, for a 16-bit environment, int is 16 bits or 2 bytes, and for a 32-bit environment, int is 32 bits or 4 bytes. The size of int datatype is usually equal to the word length of the execution environment of the program. There is a very easy way to remember the size for int datatype. This is mostly the same and is not affected by the processor or the compiler used. The char datatype is 1 byte in size or 8 bits. The size for different data types depends on the compiler and processor types, in short, it depends on the Computer on which you are running the C language and the version of the C compiler that you have installed. There are different keywords to specify these data types, the keywords are: DatatypeД®ach data type has a size defined in bits/bytes and has a range for the values that these data types can hold. This data type is mostly used when we define functions. Integer - Used to store whole numbers like 1, 2, 100, 1000, etc.ДЇloating-point - Decimal point or real numbers values like 99.9, 10.5, etc.Дouble - Very large numeric values which are not allowed in Integer or Floating point type. The C language has 5 basic (primary or primitive) data types, they are:Д¬haracter - ASCII character set or generally a single alphabet like 'a', 'B', etc. C DatatypesД«roadly, there are 5 different categories of data types in the C language, they are: TypeД¬haracter, integer, floating-point, double.

In this tutorial, we have explained the Datatypes, for code examples, checkout Using C Datatypes tutorial. Whenever we define a variable or use any data in the C language program, we have to specify the type of the data, so that the compiler knows what type of data to expect.ДЇor example, you may want to use a number like 1, 2, 100, or a decimal point number like 99.95, 10.5, or a text, like 'Studytonight', all these values are handled differently by the C language compiler, hence, we use data types to define the type of data used in any program. 100+ C Programs with explanation and outputДЄs the name suggests, a Datatype defines the type of data being used.
