Stack - an Overview

STACK is the one of the important data structure in the computer science world .
every one should know , how stack DS is implemented in program .

Lets see the below code


int add(int a ,int b)
{
  return a+b ; 
} 

add(3,5) ;  


when add is getting called , we should know ,what is happening internally and what are the information is storing in stack .


If you realize this , then you can understand the risk of using recursive function :)

well, from the above , you can infer , why thread needs separate Stack .

Stack is very simple but from that you can learn more


by the way , Don't think  Stack  is different memory . It is same as Heap , Both memory (Heap and Stack ) taken from RAM .
Small amount of memory is separated and it is surrounded by the Stack DS .
