内容概要：本文主要介绍了一个名为“修剪的灌木生长最高记录”的C++程序。程序旨在模拟灌木修剪后的生长情况，通过输入参数n（代表灌木的数量或某种边界），利用数组a记录每棵灌木被修剪的情况，数组max用于保存每棵灌木的最大生长高度。程序通过循环与条件判断，模拟了灌木的修剪和生长过程，最终输出每棵灌木的最大高度。代码中使用了goto语句实现循环逻辑，通过变量k控制方向（正向或反向遍历），并通过条件判断更新最大值。程序的核心在于通过循环不断调整灌木的高度并记录最大值。 适合人群：具有C++编程基础的学习者和开发者，特别是对算法和数据结构有一定了解的人群。 使用场景及目标：①学习如何通过循环和条件判断来模拟现实世界中的问题，如灌木的生长与修剪；②掌握数组操作技巧，包括如何用数组记录和更新数据。 阅读建议：建议读者在阅读时重点关注循环和条件判断部分，理解程序的执行流程。
