题意：

根据英语所对应的数，然后对数进行运算，输出运算结果，

#include<stdio.h>

#include<string.h>
int main()
{
char a[10][6]={"zero","one","two","three","four","five","six","seven","eight","nine"};//巧妙利用二维数组，
    int i,sum1,sum2;
char b[10];
while(1)
{
sum1=sum2=0;
while(scanf("%s",b) && strcmp(b,"+")!=0)//strcmp函数很重要
{
for(i=0;i<10;i++)
if(strcmp(b,a[i])==0) 
sum1=sum1*10+i;
}
while(scanf("%s",b) && strcmp(b,"=")!=0)//&&后面的条件别忘记
{
for(i=0;i<10;i++)
if(strcmp(b,a[i])==0) 
sum2=sum2*10+i;
}
if(sum1==sum2 && sum1==0)  break;//结果为0时结束
else printf("%d\n",sum1+sum2);
}
   return 0;
}
