将ostream转换为标准字符串
问题描述:
我对C ++ STL非常陌生,所以这可能很简单。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";
是否可以提取流并将其存储在类型为 char *
?
Is there a way to extract the stream and store it in a string of type char*
?
答
std::ostringstream stream;
stream << "Some Text";
std::string str = stream.str();
const char* chr = str.c_str();
我解释了对此问题,我是一个小时前写的。
And I explain what's going on in the answer to this question, which I wrote not an hour ago.
