  • Possible values for that type,   
  • Operations that can be performed on values of that type,

  • int, both signed and unsigned integers,  2 bytes in size.    
  • float, floating point numbers, up to 4 bytes in size.    
  • double, floating point number with double precision. These are organized in  8 bytes (64 bits)    
  • char, character type  size of 1 byte (8 bits)  It is used to form the strings i.e sequence of characters.
