Understanding recursion in the beer bottle example

Question

I am practicing recursion in C on my own and I found this example online. However there is one thing I don\'t understand.

void singSongFor(int numberOfBottle         


        

Answer 1

Step through what this is function is doing in a debugger and you will see exactly how this recursion works. I'm not being pedantic; I literally cannot think of any better way to illustrate what this is doing than referring to this interactive approach.
