bookDatatypes Modifiers

There are also name implies - datatype modifiers. They can modify the length of data that a particular data type can hold.

  • signed - to take negative and positive values.
  • unsigned - to take only positive diapason of values.
  • short - to short the diapason and memory needed for your program.
  • long - to lengthen the diapason and memory required for your program.
short int a;    // size: 2 bytes   range: -32 768 to 32 767

long int b;   // size: 4 bytes  range: -2 147 483 648 to 2 147 483 647

signed char c;   // size: 1 byte   range: -128 to 127
unsigned char d; // size: 1 byte   range: 0 to 255
question mark

We can also combine the power of two datatypes modifiers by declaring the values (it takes the features from 2 modifiers simultaneously). In your opinion, which size and sign will have the datatype unsigned short int?
