  2. Data types are the predefined keywords. it is not only used to declare the type of variables but also to do valid operations. so that the compiler may understand which variable will store what types of constant values Data type is further divided into two types 1. Integer Data type a) integer, short and long: All C compilers offer different data types , they are short and long, Short integer requires half and space in the memory than the long one, The short integer requires two bytes and the long integer’s four bytes. Difference Between Short and Long Integers. Short integer : 1. Occupies Two Bytes in Memory. 2. Range : -32768 to 32767 3. the program runs faster. 4. Format string is %d or %i. 5. Example int x=3; short int y=2; when a variable is defined without short or. long keyword, the default is short-signed int. Long integer : 1. Occupies four Bytes in Memory 2. Range : -2147483648 to 2147483647 3. the program runs slower. 4. Format string is %ld. 5. Example : long x; long int y; b) Integers, signed and unsigned: The difference between the signed integers and unsigned is provided in the given table. Difference between signed and unsigned integers.

  3. Signed integer : 1. Occupies 2 bytes in memory. 2. Range: -32,768 to 32767. 3. Control string is %d or %i. 4. By default signed int is short signed int. Unsigned integer : 1. Occupies 2 bytes in memory. 2. Range : 0 to 65535. 3. Control string is %u. 4. By default, an unsigned int is a short unsigned int.
