将 ostream 转换为标准字符串 [英] Converting ostream into standard string

问题描述

我对 C++ STL 很陌生，所以这可能是微不足道的.我有一个 ostream 变量，其中包含一些文本.

I am very new to the C++ STL, so this may be trivial. I have a ostream variable with some text in it.

ostream* pout;
(*pout) << "Some Text";

有没有办法提取流并将其存储在 char* 类型的字符串中?

Is there a way to extract the stream and store it in a string of type char*?

推荐答案

     std::ostringstream stream;
     stream << "Some Text";
     std::string str =  stream.str();
     const char* chr = str.c_str();

我解释了这个问题的答案，这是我一个小时前写的.

And I explain what's going on in the answer to this question, which I wrote not an hour ago.
