Static vs Dynamic

#1

https://ide.codingblocks.com/#/s/17057
Please look into code. I have commented out the problem.

#2

shrey a is pointing toward a memory location in heap so when u return address b also points the same in heap(which is out of scope rule) so thats why they are showing same

#3

But life of ‘a’ is finished just after function call ends. So as in the case of static allocation the value returned must be 0 and b should get value zero.

#4

but it is returning the address before getting destroyed in the main
just take an example when u make a function of factorial and return it value to main then the variable in which factorial is stored is got destroyed but u got the value in main ,same case here u having a pointer pointer to a memory in heap and when u return the address return in main,sou got the same address
Hope this help
