PAT (Basic Level) Practice 1002 写出这个数（C语言）

#include<stdio.h>

int pow(int a,int b){
	int ans=a;
	if(b==0){
		ans=1;
	}else{
		for(int i=1; i<b; i++){
			ans=ans*a;
		}
	}
	return ans;
}
int main(){
	
	char words[10][5]={"ling","yi","er","san","si","wu","liu","qi","ba","jiu"};
	char ch;
	int sum=0;
	while((ch=getchar())!='\n'){
		sum+=(ch-'0');
	}
	int n=sum;
	int index=0;
	while(n!=0){
		n/=10;
		index++;
	}index=index-1;
	
	n=sum/pow(10,index);
	sum=sum%pow(10,index);
	index--;
	printf("%s",words[n]);
	while(index!=-1){
	n=sum/pow(10,index);
	sum=sum%pow(10,index);
	index--;
	printf(" %s",words[n]);
	}
	return 0;
}

肯定变复杂了，还写了个算次方的函数…看见有人用sprintf函数做这题很方便，没接触过，到时候去了解了解模仿一下哈哈~
