How do I convert a long to a string in C++?

推荐答案

您可以使用stringstream。

You could use stringstream.

#include <sstream>

// ...
std::string number;
std::stringstream strstream;
strstream << 1L;
strstream >> number;

在编译器的标准库中通常有一些专有的C函数。我喜欢更多的便携变体虽然。

There is usually some proprietary C functions in the standard library for your compiler that does it too. I prefer the more "portable" variants though.

C的方法做到这一点是sprintf，但是不是很安全。在一些库中有新的版本，如sprintf_s，防止缓冲区溢出。

The C way to do it would be with sprintf, but that is not very secure. In some libraries there is new versions like sprintf_s which protects against buffer overruns.
