将整数限制到范围 [英] Limit integer to bounds

问题描述

我正在尝试确保int x大于或等于0但小于1080(在这种情况下为屏幕尺寸).

I'm trying to make sure that int x is greater or equal than 0 but smaller than 1080 (screen size in this case).

我想到了这个

int x = 123;
x = std::min(std::max(x, 0), 1080);

这看起来很丑.有没有更好的方法来实现这一目标?

This seems ugly. Is there a better way to achieve this?

推荐答案

如果您将来生活，可以使用 std::clamp来自C ++ 17 :

If you live in the future, you can use std::clamp from C++17:

x = std::clamp(x, 0, 1080);
