getline 函数的第一个参数应该是一个输入流(如 std::cin 或std::ifstream),第二个参数应该是一个 std::string 对象。 错误示例: 代码语言:javascript 复制 #include <iostream> #include <string> int main() { std::string line; std::getline(std::cin, line, "\n"); // 错误:第三个参数应该...
其中 cin 是正在读取的输⼊流，⽽ inputLine 是接收输⼊字符串的 string 变量的名称。下⾯的程序演⽰了 getline 函数的应⽤：// This program illustrates using the getline function //to read character data into a string object.#include <iostream> #include <string> // Header file needed ...
其中cin 是正在读取的输入流,而 inputLine 是接收输入字符串的 string 变量的名称。下面的程序演示了 getline 函数的应用: // This program illustrates using the getline function //to read character data into a string object. #include <iostream> #include <string> // Header file needed to use string...
Modify the getline member function, which can be found in the following system header file "string", as follows: 在系统头文件string中,修改getline成员函数的内容为以下形式(用记事本查找以下代码段定位): else if (_Tr::eq((_E)_C, _D)) ...
