language-agnostic - 编写一段处理上升和下降的代码的最优雅的方法是什么？

Question

我的微 Controller 项目中有以下代码:

if (newThrottle < currentThrottle)
{
    for (int set = currentThrottle; set >= newThrottle; set--)
    {
        // Perform actions to set the throttle
    }
}
else
{
    for (int set = currentThrottle; set <= newThrottle; set++)
    {
        // Perform actions to set the throttle
    }
}

如果不是很明显，此代码片段用于将电机 throttle 从当前值向上或向下倾斜到新值。

有没有更优雅的方式来写这个？

Answer 1

int add = (newThrottle > currentThrottle) ? 1 : -1;

while (newThrottle != currentThrottle)
{
    // do your stuff
    currentThrottle += add;
}
