#C recursive sequentially output integer

This problem required to achieve a function of an output bit sequence of integers.

Function interface definition:

void printdigits( int n );

Function printdigitsshould be nevery digital print order from high to low, each digit per line.

Referee test program Example:

#include <stdio.h>

void printdigits( int n );

int main()
{
    int n;
	
    scanf("%d", &n);
    printdigits(n);

    return 0;
}

/* 你的代码将被嵌在这里 */

Sample input:

12345

Sample output:

1
2
3
4
5

 1 #include <stdio.h>
 2 
 3 void printdigits(int n);
 4 
 5 int main() {
 6     int n;
 7 
 8     scanf("%d", &n);
 9     printdigits(n);
10 
11     return 0;
12 }
13 
14 void printdigits(int n) {
15     if (n < 10) {
16         printf("%d\n", n);
17     } else {
18         printdigits(n / 10);
19         printf("%d\n", n % 10);
20     }
21 }
