现在我想在代码中添加一个名为"category"的新数组。我应该添加一个数组，并可以让它与我的其他代码一起打印出来。我已经为2014年的类别尝试了if语句。它告诉我没有语法错误，但没有打印任何内容。我还想格式化我的代码，使它们都在列中，看起来井然有序。我试了几种方法，但都没有改变。我现在说的没有格式，没有那么重要，但如果有人能帮忙，我们将不胜感激。

/**

speed of Atlantic hurricanes that have occurred between a given year
range. Also, tally the number of storms in each category according to the
Saffir-Simpson scale.

不太确定你在要求什么，但是您应该将if-else嵌套语句改为循环，而不是
