A1005:Spell It Right(20')
思路
将输出单独存进一个二维字符串数组中,遍历求各位上数的和,再用辗转相除法求出和的每一位数字,存进数组,最后逆序输出。
注意
特判 sum=0。
代码
#include<cstdio>
#include<cstring>
int main(){
char a[10][10] = {"zero","one","two","three","four","five","six","seven","eight","nine"};
char n[10010];
scanf("%s",n);
int len = strlen(n);
int sum = 0;
for(int i = 0; i < len ; ++i){
sum += n[i] - '0'; //字符化为整数
}
int x[10010] = {0}; //要加{}
int i = 0;
//特判
if(sum == 0){
printf("zero");
return 0;
}
do{
x[i++] = sum % 10;
sum /= 10;
}while(sum != 0); //用do while
for(i-- ; i >= 0 ; --i){
printf("%s",a[x[i]]);
if(i != 0) printf(" ");
}
return 0;
}
