返回字符串 [英] returning strings
问题描述
我们如何从函数返回字符串或数组？我试过..
char [] some_func（）//我认为char []会告诉编译器
返回是一个字符串
{
char str [100];
//某事物;
返回str;
}
提前感谢！
how do we return strings or arrays from a function? i tried..
char[] some_func() //where i thought char[] would tell the compiler
that the return is a string

}
thanks in advance!

你在写C ++而不是C，这样做
std :: string some_func（）
{
std :: string str;
//某事物;
返回str;
}
You''re writting C++ not C, do it like this
std::string some_func()
{
std::string str;
// something;
return str;
}
我在使用TC ++（一些旧版本）。请建议一些有效的东西
。
i work on TC++ (some old version). Please suggest something that works
in the same.

因为当函数返回返回的
值时，它不会工作得太好已经死了。
您是否阅读过常见问题解答？
That won''t work too well since by the time the function returns the
value being returned is dead.
Did you read the FAQ?
