1/29/2024 0 Comments Basic data types![]() We use the void keyword for void data type. The void data type is used when a function does not return anything. ![]() This data type is mostly used when we define functions. We can perform addition, subtraction, division and multiplication operations on double data type. double a = 10.09 ĭouble has more precision than flaot so double gives more accurate results as compared to float. It occupies 8 bytes of memory and ranges from 1e-37 to 1e+37. ĭouble: We use the keyword double for double data type.We can perform addition, subtraction, division, and multiplication operations on float data type. For example, float a = 0.05 įloat c = 1 // it will become c = 1.000000 because of type-casting It occupies 4 bytes of memory and ranges from 1e-37 to 1e+37. įloating-point: We use the keyword float for floating-point data type.We can perform addition, subtraction, division, multiplication, bitwise and modulo operations on int data type. The range of int is -2,147,483,648 to 2,147,483,647 and it occupies 2 or 4 bytes of memory, depending on the system you’re using. The int data type is used to store non-fractional numbers which includes positive, negative and zero values. Integer: We use the keyword int for integer data type. We can perform addition and subtraction operations on char but the ASCII value should not exceed 127. More specific data types are as follows: varchar (. For example, char a = 'a' įor char datatype, it is necessary to enclose our data in single quotes. Some common data types are as follows: integers, characters, strings, floating-point numbers and arrays. We can store alphabets from A-Z(and a-z) and 0-9 digits using char. It is used to store single bit characters and occupies 1 byte of memory. The C language has 5 basic (primary or primitive) data types, they are:Ĭharacter: We use the keyword char for character data type. Enumeration enums Bool type true or false void Empty value Data Types in Cīroadly, there are 5 different categories of data types in the C language, they are: Type Example Basic character, integer, floating-point, double. For code examples, checkout Using C Datatypes tutorial. In this tutorial, we have explained the different data types used in C language. 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.įor 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.Įach data type occupies some memory, has a range of values and a set of operations it allows to be performed on itself. As the name suggests, a Datatype defines the type of data being used.
