2) 同getline(input, str, input.widen('\n')),即默认分隔符是换行符。参数input - 获取数据来源的流 str - 放置数据的目标字符串 delim - 分隔字符 返回值input 注解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...
变量、函数、模板形参对象(C++20 起)或数据成员的名字,不论类型,例如std::cin或std::endl。即使变量的类型是右值引用,由它的名字构成的表达式仍是左值表达式(但请见有移动资格的表达式); [展开]延伸内容 返回类型是左值引用的函数调用或重载运算符表达式,例如std::getline(std::cin, str)、std::cout<<1、str...
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; 3) a = ...
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 assignment and compound assig...
