0Data types in C Language
Data types specify how we enter data into our programs and what type of data we enter. C language has some predefined set of data types to handle various kinds of data that we use in our program. These datatypes have different storage capacities.
C language supports 2 different type of data types,
Primary data types: These are fundamental data types in C namely integer(int), floating(float), charater(char) and void.
Derived data types: Derived data types are like arrays, functions, stuctures and pointers. These are dicussed in detail later.
Integer type: Integers are used to store whole numbers.
| Size and range of Integer type on 16-bit machine Type | Size(bytes) | Range |
| int or signed int | 2 | -32,768 to 32767 |
| unsigned int | 2 | 0 to 65535 |
| short int or signed short int | 1 | -128 to 127 |
| long int or signed long int | 4 | -2,147,483,648 to 2,147,483,647 |
| unsigned long int | 4 | 0 to 4,294,967,295 |
