C provides various types of data-types which allow the programmer to select the appropriate type for the variable to set its value. Data-type is used to identify the type of the variable when it declare. And also used in identify the type of the value returned by the function.
C have three type of the data-type:-
- Primary (built-in ) data types:- Void , int , char, float, double.
- Derived data Types :- Array , pointer .
- User define data types :- structure , union and enumeration .
Void:- It holds no value and is generally used for specifying the type of function or what it returns. If the function has a void type, it means that the function will not return any value.
Int :- It is used to declare the integer type values. For int we use %d .
Char :- it is used for character type values. For char we use %c .
float , Double :- It is used for floating numbers. For float we use %f and for double we use %lf.
All the data type have a specific range they can not store the value greater than that range value . and range of the data type is depending on the compiler (16 bit or 32 bit) .
