[英]How to reset all variables in a struct in C++?
I know how to reset the variable manually one by one, but is their anyway I could call the struct function to re-read the menu(): part? 我知道如何手动一个个地重置变量,但是无论如何我可以调用struct函数来重新读取menu():part吗? Because those variables are already by default.
因为这些变量已经是默认设置。 Or do I have to reset them one by one myself?
还是我必须自己一个个重置它们?
struct menu
{
bool update;
bool enterPressed;
int scroll;
int choice;
int type;
menu(): update(true), enterPressed(false), scroll(0), choice(0), type(0) {}
} menu;
Easiest way with the above code is to copy from a new instance, eg: 上面的代码最简单的方法是从新实例复制,例如:
menu blah;
// reset blah to defaults
blah = menu();
With C++11, this will work: 使用C ++ 11,这将起作用:
menu m;
// ...
m = {};
This will create a temporary menu
and assign it to m
. 这将创建一个临时
menu
并将其分配给m
。
