            int scanf( const char *format [,argument]... );
            A return value of 0 indicates that no fields were assigned. The return
            value is EOF for an error or if the end-of-file character or the
            end-of-string character is encountered in the first attempt to read a
            character.

            scanf()函數接收輸入數據時,遇以下情況結束一個數據的輸入
                    ① 遇空格、“回車”、“跳格”鍵。
                    ② 遇寬度結束。
                    ③ 遇非法輸入。



            關于scanf的返回值,
            MSDN:
            Both scanf and wscanf return the number of fields successfully converted
            and assigned; the return value does not include fields that were read but
            not assigned. A return value of 0 indicates that no fields were assigned.
            The return value is EOF for an error or if the end-of-file character or the
            end-of-string character is nocountered in the first attempt to read a character
            就是返回的是正確讀入的數據的個數
