Re: [algogeeks] Re: C puzzle
in fn,ptr first recieves the address of i,and then by ptr=val,it now stores the address of val variable. while in fn1,ptr first stores the address of i,and then by *ptr=100,value at the address of i changes to 100.and hence it gives 100 as the answer.

In fn, ptr is a local variable passed by value. Changing ptr in the
function does not change anything in main.

What is the difference between fn and fn1?
I expected the output to be 10 100 100
but it came as 10 10 100.
can anyone explain what happens in fn.
why 100 in fn is not stored in ptr.
