//刚写的code，测试通过，如果有疑问，欢迎交流
#include<stdio.h>

char digit_lib[10][5] = {"ling","yi","er","san","si","wu","liu","qi","ba","jiu"};

void print_pos_digit(int tar, int *is_first){
	if(tar==0){
		*is_first = 1;
		return;
	}
	print_pos_digit(tar/10, is_first);
	if(*is_first == 1){
		printf("%s", digit_lib[tar%10]);
		*is_first = 0;
	}
	else 
		printf(" %s", digit_lib[tar%10]);
}

int main(){
	int tar;
	scanf("%d", &tar);
	int flag = 0;
	if(tar<0){
		printf("fu ");
		print_pos_digit(-tar, &flag );
	}else
		print_pos_digit(tar, &flag);
	printf("\n");
}

Answer 2

#include <stdio.h>
#include <string.h>
int main()
{
    char str[20];
    char py[][6]={"ling","yi","er","san","si","wu","liu","qi","ba","jiu"};
    scanf("%s",&str);
    if(str[0]=='-') printf("fu");
    else printf("%s",py[str[0]-'0']);
    for(int i=1;str[i]!=0;i++)
        printf(" %s",py[str[i]-'0']);
}
