补个更简单（懒）的写法

#include <bits/stdc++.h>
using namespace std;

vector<string>fuck{ "zero","one","two","three","four","five","six","seven","eight","nine" };
int trans(string s)
{
    return find(fuck.begin(), fuck.end(), s) - fuck.begin();
}
int main()
{
    int T; cin >> T;
    for (int I = 0; I < T; I++)
    {
        string s;
        int a = 0, b = 0;
        while (1)
        {
            cin >> s;
            if (s == "+")break;
            a = a * 10 + trans(s);
        }
        while (1)
        {
            cin >> s;
            if (s == "=")break;
            b = b * 10 + trans(s);
        }
        printf("case #%d:\n%d\n", I, a + b);
    }
    return 0;

先把字符串中所有的单词分离出来，放在二维数组中。
前两个单词放在二维数组的第一个和第二个，后两个单词放在二维数组的倒数第三个和倒数第二个里面；
然后再分别计算出所代表的数字相加即可。
