c ++如何将double放入String中

Question

那么在带有字符串的java中你可以这样做:

int stuff;
string otherstuff;

otherstuff = "I like this much stuff: " + stuff;

但在C++中我不知道如何.

Answer 1

在C++ 11中:

otherstuff = "I like this much stuff: " + std::to_string(stuff);

历史上(有时在C++ 11中有用):

std::ostringstream ss;
ss << "I like this much stuff: " << stuff;
otherstuff = ss.str();
