![]() ![]() _Imaginary Declaration of Primary Data Types with Variable NamesĪfter taking suitable variable names, they need to be assigned with a data type.Three more data types have been added in C99: int *, float *, char * Used to denote a pointer type. float, double Used to denote a floating point type. If the function has a void type, it means that the function will not return any value. Primary Data TypesĮvery C compiler supports five primary data types: void As the name suggests, it holds no value and is generally used for specifying the type of function or what it returns. User Defined Data Types: Structure, Union, and Enumeration.Derived Data Types: Array, References, and Pointers.Primary(Built-in) Data Types: void, int, char, double, and float.C provides various types of data-types, allowing the programmer to select the appropriate type for the variable to set its value.
