错误 C2679:二进制“<<": 没有找到使用“std::string"类型的右侧操作数的运算符(或者没有可接受的转换)
这是我的代码,我该如何解决这个错误?
Here's my code, how do I fix this error?
#include "stdafx.h"
#include <iostream>
using namespace std;
int main()
{
string title = "THE WORLD OF PIRATES";
cout << title << endl;
cout << " Welcome to the world of pirates";
cin.get();
return 0;
}
错误是
binary '<<' : no operator found which takes a right-hand operand of type 'std::string' (or there is no acceptable conversion)
推荐答案
您忘记了 #include
使用 std::string
而不包含它的头文件适用于一些间接将
的部分导入到它们的
的编译器code> 或其他标题,但这不是标准的,不应依赖.此外,当您尝试输出字符串时,它们经常会中断,因为它们只包含实现的一部分,而缺少实现 operator<<
的部分.
using std::string
without including it's header works on some compilers that indirectly import parts of <string>
into their <iostream>
or other headers but that's not standard and shouldn't be relied upon. Also they often break when you try to output a string since they only included a part of the implementation and are missing the part that implements the operator<<
.
