codeforces #299 div 2

（总算是5题都做完了- -）

暂时做了4题，先放一下有时间做最后一题（当然如果我真的能做出的话。。。）（看了大神的代码总算是理解了E题，做完发现也没那么难，果然想出一个思路的过程对于我这种弱渣来说还是太强求了啊。。。）

A题：

英文单词别拼错就没什么问题吧

#include <cstdio>
#include <cstring>

using namespace std;

char str[10][10] = {"" , "" , "twenty" , "thirty" , "forty" , "fifty" , "sixty" , "seventy" ,"eighty" , "ninety"};
char single[10][10] = {"zero" , "one","two","three","four","five","six","seven","eight","nine"};
char dou[10][10] = {"ten" ,"eleven","twelve","thirteen","fourteen","fifteen","sixteen","seventeen","eighteen","nineteen"};
int main()
{
    int x;
    while(~scanf("%d" , &x)){
        if(x<10){
            printf("%s\n" , single[x]);
        }
        else if(x<20){
            printf("%s\n" , dou[x%10]);
        }
        else{
            int tmp = x%10;
            printf("%s" , str[x/10]);
            if(tmp){
                printf("-%s" , single[tmp]);
            }
            printf("\n");
        }
    }
    return 0;
}
