更好的解决方案可以在O(n)的时间解决这个问题。这个想法是跟踪到目前为止所看到的非空格字符的计数。 1)初始化'count'= 0(到目前为止看到的非空格字符的计数) 2)遍历给定字符串的所有字符,请执行以下操作 a)如果当前字符为非空格,则放置此字符 在索引“计数”处增加“计数” ...
std::istringstream iss; std::stringbuf *pbuf = iss.rdbuf(); // using stringbuf directly:直接用stringbuf作为输入,最终表现仍然是istringsteam对象 pbuf->str("Example string"); int size = pbuf->in_avail(); while (pbuf->in_avail()>0) std::cout << static_cast<char>(pbuf->sbumpc()); ...
Thegetlinefunction returns itsistreamargument so that, likethe input operator, it can be used as a condition. For example, wecould rewrite the previous program that wrote one word per line towrite a line at a time instead: getline函数将istream参数作为返回值,和输入操作符一样也把它用作判断条件。
