Because each data type uses a certain number of "bits" to store their values, and thus are mathematically limited to the amount of data they can hold before losing information. You can think of an analogy of your mailbox and letters you receive. You can only fit so many letters into the mailbox before it physically cannot hold any more letters.
You can not change the range of a data type. It is a function of the implementation and is dependent on the word size of the implementation's computer hardware.
Describe the basic data types in C Describe the basic data types in C
Unlike C and C++, all built-in data types in C# are not implementation-defined, they are consistent across all implementations. An int always occupies 32-bits, thus the range of valid values is -2,147,483,648 to 2,147,483,647 inclusive.
The data types indicate the type of values that can be stored. The primary data types in c are:1. int, short, long, long long - used for integer values2. float, double - used for storing floating point numbers3. char - used for storing ASCII characters
You seem to have lost your text book so I am giving you a link where you can study data types, including derived data types.
The ranges for all data types in C are implementation-defined.

The usual C datatypes, nothing special.

In c language data types are used to specify the tye of data.for ex:int a;It means "a" is a variable of type integer.There are two types of data types in c.They areprimary data typessecondary data typesprimary data types are the built in data types and secondary data types are the user defined data types.eg for primary data types are int,float,char,long,double..and for secondary are arrays,structures,pointers,unions..
data types supported by "C" are int , float , char , long , double , uint
arrays in C are the data types which have collection of same type of data together store a fixed-size s of elements .
In Pascal, data structures are implemented with recorddata types. A record is synonymous with the structdata type in C, or the class data type in C++.
C++ is only partially OOP because it is a superset of C and, for the sake of backward compatibility, retains the concept of primitive data types (such as integrals like char and int) and pointer data types, which are all strictly non-object-oriented. In Java and C#, there is no concept of a primitive data type. Even integral types such as int are treated as objects and there is no concept of a pointer data type.
