Hi,

DataType

AX - Primitive and composite

primitive:

1) int [32]
2) int 64 - long int [ credit card numbers, debit card numbers]
3) real - decimal points example : 12346.00 [12 digits]
4) str  - sequence of characters [ lengTH - 10]

5) Base Enums: enumerations [ fixed set of constants/literals]

  - constant - will never change

example : week [ sunday 0, m1, t 2, we 3, thu 4, fri 5, sat 6]
 Year [j........d]
gender [ m, f, uk]

enum value starts with 0
Largest value it can hold is 250

6) Date - in order to hold any date values [mm/dd/yyyy], dd/mm/yyyy 20-Aug-2010

7) Time - integer

8) DateTime - 12/23/2011 2:00:05 PM

10) GUID - Global unique identifier - 24 digit hexa decimal number which system will generate automatically

Composite data types:

1) Arrays -  collection of similar datatypes:

1) Index starts with 1

EXAMPLE :

str names[11]; //static array
// dynamic array str names[]
names[1] = "Kabir";
names[2] = "Khan";
;
;
