《 C++ Crash Course 》上有个例程如下：
``` c++
struct JohanVanDerSmut
{
bool gold = true;
int year_of_smelting_accident{1970};
char key_location[8] = {"x-rated"};
};
```
我编译后程序报错：
error: invalid conversion from ‘const char*’ to ‘char’ [-fpermissive]
char key_location[8] = {"x-rated"};
^
是编译器版本的问题吗？？我用的是 gcc 5.4
