"Fundamentals of program design" Chapter 10 function and program structure 6-6 recursive implementation sequential output integer (15 points)

This question requests to realize a function , Output an integer in bit order .

Function interface definition ：

void printdigits( int n );

function printdigits Should be n Each digit of the is printed in order from high to low , Each number is on one line .

Sample referee test procedure ：

#include <stdio.h>

void printdigits( int n );

int main()
{
    int n;

    scanf("%d", &n);
    printdigits(n);

    return 0;
}

/*  Your code will be embedded here  */

sample input ：

12345

No blank lines at the end

sample output ：

No blank lines at the end

void printdigits( int n )
{
    int i=0;
    int a[100];
    if(n==0)    printf("0");
    else
    {
    while(n>0)
    {
        a[i++]=n%10;
        n/=10;
    }
    int m;
    for(m=i-1;m>=0;m--)
    {
        printf("%d\n",a[m]);
    }
    }
}
