消耗空白符分隔的输入(例如 int n; std::cin >> n;)时,任何后随的空白符,包括换行符都会被留在流中。然后当切换到面向行的输入时,以 getline 取得的首行只会是该空白符。多数情况下这是不想要的行为,可能的解法包括: 对getline 的显式的额外初始调用 以...
basic_istream&getline(char_type*s,std::streamsizecount, char_type delim); (2) 从流提取字符,直至行尾或指定的分隔符delim。 重载(1)等价于getline(s, count, widen('\n'))。 表现为无格式输入函数(UnformattedInputFunction)。构造并检查 sentry 对象后,从*this提取字符并将它们存储于以s指向其首元素的...
(变量,函数都是左值) a function call or an overloaded operator expression of lvalue reference return type, such as std::getline(std::cin, str), std::cout << 1, str1 = str2, or ++it; (运算符重载并且返回值是引用的方法) a = b, a += b, a %= b, and all other built-in assign...
basic_istream& getline( char_type* s, std::streamsize count, char_type delim ); (2) Extracts characters from stream until end of line or the specified delimiter delim. The first overload is equivalent to getline(s, count, widen('\n')). ...

1) 在作用域(scope)内的、无论什么类型的变量名或者函数名。比如,std::cin或者std::endl。即使这个变量的类型是右值引用,由它的名字组成的表达式也是个左值表达式。 2) 把左值引用作为返回的函数或者重载操作符。 比如,std::getline(std::cin,str),std::cout << 1, str1 = str2, 或 ++it; ...
