//我输入大于7个字母的单词，它仍然用猪拉丁语给出它，而不是提示另一个单词。我尝试放入一个while循环，但它只是给出一个无限循环

         //while (count<7)
         //
        printf("\n%s in Pig Latin: ",str1);
        for (i=1;str1[i];++i)
            {
            printf("%c",str1[i]);
            }
        printf("%c",str1[0]);
        printf("ay");
        printf("\n\n\n");
         //}


    }while(str1!= "END");

//此外，它不会通过输入END结束。我究竟做错了什么？

return 0;
    }

Answer 1

更改

}while (count>7);//loop to perform if invalid word is entered

要

}while (count==0);//loop to perform if invalid word is entered

和

}while(str1!= "END");

要

}while(strcmp(str1,"END")!=0);

另外，请勿忘记添加string.h

do while循环中的字符串
