if(!avf) 因为这句是写在初始化之后的，这个avf是判断打开文件是否成功，如果不成功则会返回一个0值。while(avf>>Value) 这个是判断流输入的，流有3个常用的状态 1. int bad(); //操作出错时返回非0值。2. int eof(); //读取到流中最后的文件结束符时返回非0值。3. in...

Attempts to decrease the current location in the stream by one character, making the last character extracted from the stream once again available to be extracted by input operations.注意:当字符c与最后一次从流中抽取的字符不匹配时,该函数的动作与特定的流缓冲区有关,即string buffer或file buffer。
