Erorr：无操作符“>>>匹配这些参数 [英] Erorr: no operator ">>" matches these arguments

问题描述

int main()
{ 
char* NamePointer = new char;


std::cout << "Enter the file you want to edit (MUST BE IN THE PROJECT'S DIRECTORY): ";
std::cin >> &NamePointer;

const char* FileName = NamePointer;
delete &NamePointer;


return 0;
}

这会返回标题中的错误：

This returns me the error in the title:

std::cin >> &NamePointer;

任何想法？这可能是一个简单的我失踪，但当我查找它，我没有得到我的答案。

Any ideas? This is probably something simple I'm missing, but when I looked it up I didn't get my answer.

JUST FIXED IT，SORRY FOR BOTHERING！我拿出了&在& NamePointer中。

是的，我刚刚发现了另一种方法使用c_str（）。很抱歉！

Yeah I just found out another way of doing this using c_str(). Sorry!

推荐答案

您应该有：

std::cin >> NamePointer;

此外，你只是分配一个字符的内存，可能你的意思是：

Also, you are just allocating an memory of one character, probably you meant:

char* NamePointer = new char[MAX_SIZE];

并将其分配为：

delete []NamePointer;

/www.cplusplus.com/reference/string/string/rel =nofollow> std :: string 来处理缓冲区溢出问题你可以使用 char * ：

Note that the, C++ way of doing this is to simply use std::string which takes care of the problem of buffer overflows you get with using char*:

std::string Name;
std::cin >> Name;
