Data Types - Coggle Diagram

- - - - called integer literals
      - used for integers which are more than short integers
      - numbers are represented without decimal points
      - includes negative numbers
      - example - -123 and 123
      - Data
        
        Byte
        
        8 bits
        
        Short
        
        16 bits
        
        int
        
        32 bits
        
        long
        
        64 bits
      - Declaring
        
        int a = 1200;
    - - When you need to store a fractional nnumber
        
        Double
        
        Larger range
        
        64 bits
        
        double p; p=7.9016453
        
        Float
        
        Small range
        
        32 bits
        
        float a; a=2.96
  - - - a characters are declared using "char p;" p = 'x'
      - Some well known characters and their ASCII code are as follows:
        
        A-Z : 65 - 90
        
        a-z : 97 - 122(Respectively)
        
        0-9 : 48 - 57
      - Syntax<Data type><variable> = <'character literal'>
      - char c = 'h';
      - Can hold only one charecter at a time
    - - special literals
      - True or false
      - if the condition is satisfied, the result will be true and if not, it will be false
      - boolean constants are not
        enclosed within quotes text
      - boolean a = true
      - 0 bytes of memory
