WebWhen a function calls itself, then its called recursion. That is the most basic definition. This definition is enough when you need to solve basic problems like fibonacci series, factorial, etc. This is the implicit use of recursion.

Webrecurse ( count + 1 ); } int main () { recurse ( 1 ); } This simple program will show the number of times the recurse function has been called by initializing each individual function call's count variable one greater than it was previous by passing in count + 1. WebJul 28, 2013 · For example, what will they do after they can't call the function again? For example, here, I can understand it prints from 3 to 0 but why it also prints from 0 to 3 again? I heard it's because function recursion is stored in a stack for one recursion and when it reaches the "bottom" it also has to delete. But anyway, I don't know about it.
