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...
首先,确认你的C++编译器和标准库版本是否支持std::getline函数。通常情况下,std::getline是C++标准库中的一部分,应该在大多数现代C++编译器和标准库版本中都是可用的。 解释getline函数在C++标准库中的位置: getline函数实际上有两种形式: 一种是std::basic_istream::getline,它是istream类的成员函数,用于从输入...
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')). ...

Using std::getline() to read from input streams Now that we know the basic syntax, let’s get input fromstd::cin(standard input stream) to a string. #include<iostream>#include<string>intmain(){// Define a name (String)std::string name;std::cout<<"Enter the name: ";// Get the ...
