What is really happening in this code?

Question

I have a code which includes a recursive function. I have wasted a lot of time on recursion but I still couldn\'t get it really:

#include
void         


        

Answer 1

While m is greater than 0, we call count. Here is a representation of the stack calls:

 count (m = 10)  
   count (m = 9)  
     count (m = 8)  
       count (m = 7)  
         count (m = 6)    
           count (m = 5)     
             count (m = 4)     
               count (m = 3)     
                 count (m = 2)     
                   count (m = 1)
                     count (m = 0)
                     printf 0
                   printf 1
                 printf 2
               printf 3
             printf 4
           printf 5
         printf 6
       printf 7
     printf 8
   printf 9
 printf 10
