题目链接:http://acm.hdu.edu.cn/showproblem.php?pid=1013 反思:思路很简单,但是注意各位数加起来等于10的情况以及输入0的时候结束程序该怎么去表达 #include<stdio.h> #include<string.h> char a[1000000]; int main() { int i; int sum=0; while(gets(a)&&a[0]!='0') { sum=0; for(i=0;a[i]!='\0'…

tips:分析不够仔细,白费了许多功夫.输入数据的范围,平时几乎很少考虑的,这个以后得注意.代码检查不够仔细啊,以后得注意了 #include<iostream> using namespace std; void main() { int n=0,sum=0; char s[1000]; while(cin>>s) { n=0; sum=0; if(strcmp(s,"0")==0) break; int len=strlen(s); for(int i=0;…
