替代 itoa() 将整数转换为字符串 C++?
我想知道是否有 itoa() 的替代方法可以将整数转换为字符串，因为当我在 Visual Studio 中运行它时会收到警告，并且当我尝试在Linux，我得到一个编译错误.
I was wondering if there was an alternative to itoa() for converting an integer to a string because when I run it in visual Studio I get warnings, and when I try to build my program under Linux, I get a compilation error.
推荐答案
在 C++11 中你可以使用 std::to_string:
In C++11 you can use std::to_string:
#include <string>
std::string s = std::to_string(5);
如果您使用的是 C++11 之前的版本，则可以使用 C++ 流:
If you're working with prior to C++11, you could use C++ streams:
#include <sstream>
int i = 5;
std::string s;
std::stringstream out;
out << i;
s = out.str();
