DATA STRUCTURES

1. Array ---> Computed Offsets
2. Object
3. Dynamic Structures (Linked List)
4. Union Structure --> Named of sets
5. Record / Struct -->

1. Array: 

.

.

.

ARR[5] = 7; Compute

. ADDR ARR ==> B.A + 100  ==> "x"

2. oBJECT

3. dYNAMIC Structures (Link List)

4. UNION Structure

5. Record / Struct

example:

Record Student Record:

NAME	char[20]    offset is 0
AGE	int    offset is 20
GPA	FLOAT    offset is 24
.	.

StudentRecord s;

s.AGE = 14; // what address should be interpreted for AGE (its called Name Offset)

     |

     |

     code to 

complete LHS address?    Lets say X = BaseAddress + 200

 (take X and start adding the sizes of other data types )
