我的目标是设置一个数据结构来存储我的应用程序的设置.
在PHP中,我只会写…
$settings = array(
"Fullscreen" => true,"Width" => 1680,"Height" => 1050,"Title" => "My Application",);
现在我试图在C中创建一个类似的结构,但它不能处理不同的数据类型.顺便说一句,如果有更好的方式存储这些设置数据,请让我知道.
struct Setting{ string Key,Value; };
Setting Settings[] = {
("Fullscreen","true"),// it's acceptable to store the boolean as string
("Width","1680"),// it's not for integers as I want to use them later
("Height",1050),// would be nice but of course an error
("Title","My Application") // strings aren't the problem with this implementation
};
如何使用灵活的数据类型来建立关联数组的结构？
解决方法
具有不同数据类型的关联数据结构正是一个结构体…
struct SettingsType
{
bool Fullscreen;
int Width;
int Height;
std::string Title;
} Settings = { true,1680,1050,"My Application" };
现在,也许你想要一些反思,因为字段名称会出现在配置文件中？就像是：
SettingsSerializer x[] = { { "Fullscreen",&SettingsType::Fullscreen },{ "Width",&SettingsType::Width },{ "Height",&SettingsType::Height },{ "Title",&Settings::Title } };
只要你给SettingsSerializer一个重载的构造函数,具有不同的行为,这取决于指向成员的类型,你会得到你.
