函数返回字符串 [英] Function return string
问题描述
为什么函数不能返回字符串？ （错误：新类型可能不是
在返回类型中定义）...
我该如何解决？
我想到的将字符串传递给函数，但这将使我重新设计大部分应用程序并且我想避免它..是否有任何其他
方法来克服这个问题？

Why can''t a function not return string? (error: new types may not be
defined in a return type)...
How can i solve it?
I thought of passing the string into the function, but that will make
me redesign most of the app and i want to avoid it.. is there any other
way to overcome this?

你这里写的没有代码，所以很难想到，你的
问题。但肯定有可能返回字符串：
#include< string>
std :: string RetString（）
{
返回" Hello" ;;
}
如果你的意思是返回C字符串，它也适用：
const char * RetCString（）
{
return" Hello" ;;
}
You wrote here no code, so it is very hard to think, where is your
problem. But there is definitely possible to return strings:
#include <string>
std::string RetString()
{
return "Hello";
}
If you mean returning C-strings, it works too:
const char* RetCString()
{
return "Hello";
}

请粘贴一段代码。没有什么可以阻止你返回一个类或一个C风格的字符串来获得
。
另外，请发布你正在编译它的编译器和操作系统。
Please paste a snippet of your code. There is nothing stopping you
from returning a class or a C style string.
Also, please post what compiler and OS you are compiling this on.

感谢快速回答:)
我试过这个并且它有效：s
但是
i有
class a
{
public：
string getit（）;
私有：
字符串astring;
}
i尝试编译它并说出错误提到以上......
thanks for the quick answer :)
well i tried this and it works :s
BUT
i have
class a
{
public:
string getit();
private:
string astring;
}
i try to compile it and is says the error mentioned above...
