I believe it is only at the very end once, at thats on line 86, which is the first read from the end of file. From there though, it moves backwards away from the end. I did have a bug where it read past end of the file, because I wasn't seeking back to the beginning of the...
while(inf >> x) // Attempt read into x, return false if it fails { // will only be entered if read succeeded. } 这正是我们想要的。 - Thanatos3 应该不要使用 >> 替代 get()。请记住,>> 运算符始终会跳过尝试读取下一个值之前的所有空白字符,而 get() 会一次读取一个字符。 - Martin ...
The only simple statement (cout << c;) of the while compound statement sends a copy of the character to the output. Instead of sending the characters to the output, they can be sent to a string object, forming a long string as follows: char c; string str; while (ifs.get(c)) str...
