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

//我输入大于 7 个字母的单词，它仍然以 Pig Latin 给出，而不是提示输入另一个单词。我试图放入一个 while 循环，但它只是给出了一个无限循环

         //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"); 

//这里也不是输入END结束。我究竟做错了什么？

return 0;
    }

Answer 1

改变

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

至

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

还有

}while(str1!= "END");

至

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

另外，不要忘记包含 string.h
