C++ 有没有办法尽量减少IF声明的数量？

我的代码中充满了If语句，我想减少If语句的数量，如果不是全部去掉的话。我该怎么做？任何其他提示和改进都非常感谢！ 我刚刚开始学习编写代码，并跟随导师写了这篇文章，但我很难理解如何最大限度地减少IFs的数量

这是一个非常广泛的、开放式的软件设计问题，不仅仅是C++。
在大多数情况下，您将无法删除
if
s，因为您有条件逻辑——这很好。但是，您可以遵循一些设计实践，以减少每个函数的
if
语句：


将逻辑分解为更小的函数，以隔离它们的关注点。例如，每个不同的
作战
动作都可以是单独的函数。这不会减少
if
s，而是将每个函数的嵌套量限制在逻辑上需要的位置

查找重复的代码或模式，并将它们提取到函数中。同样，这有助于将
if
s限制在需要它们的地方

使用
开关代替
if
/
else
梯形图

使用较小的函数，您可以更改
if
语句以检查提前终止情况，并提前返回以避免嵌套。这会使嵌套更短，因为提前返回后的主分支隐式地是
else
。例如：


void check\u user\u death（）
{
//而不是“如果”（character.totalHealth欢迎使用SO！您的代码是否按照您的意愿工作，并且只想重构它？您当然应该学习如何使用
switch
语句。您可能会希望将代码分解为更多的函数。看起来您的一些函数做得太多了。另外，当您使用时，不要养成使用递归的习惯应该使用循环。
