Will want to excuse me which bosses: using recursive method to input an integer in C 531, print out the 5,3,1

CodePudding user response:

 # include & lt; Stdio. H> 

Void print_number (int n); 

Int main (void) 
{
Int num=531; 

Print_number (num); 

printf("\n"); 

return 0; 
} 

Void print_number (int n) 
{
If (n==0) 
return; 

Print_number (n/10); 
Printf (" % d ", n % 10); 
} 

For your reference ~
