Simple recursion

[amphinomos]

Hi,

I'm trying to understand the flow of recursive formulas and how the variable is being stored in memory. Simple example below :

which prints:

If I step into the code, before each print of "I'm looping" the execution leaves the if and the function then comes back inside. How is that possible ? How are "num" and myFact stored ?

Thanks,
amphi

It is same as when you call other function. Code passes to called function and returns when complete. In this case you call same function but principle is same (you may look at call stack) - you have chain of 5 calls to function and control pass back up stack when num is 1 for last call.

Thanks didn't know you could monitor the call stack...
