C ++从1个字符转换为字符串？ [英] C++ convert from 1 char to string?

问题描述

我真的没有找到任何关闭的答案...

I really didn't find any answer that close...

相反的方式很简单，像str [0]

the opposite way is pretty simple like str[0]

但我需要只转换1个字符到字符串...

But I need to cast only 1 char to string...

像这样：

char c = 34;
string(1,c);
//this doesn't work, the string is always empty.

string s(c);
//also doesn't work.

boost::lexical_cast<string>((int)c);

//also return null

感谢

推荐答案

所有

string s(1, c); std::cout << s << std::endl;

和

std::cout << string(1, c) << std::endl;

和

string s; s.push_back(c); std::cout << s << std::endl;

为我工作。
