使用一组规则洗牌数组并从函数返回值 我对C++比较陌生，我今年才开始学习它。 我很难编写一个小程序来接收文本文档并将其存储在数组中。然后取那个数组，以某种方式将值随机化。这是一个排班计划，以安排骑手+马到合适的位置

我试图在这个函数（gen（））中尝试将条目[num]复制到entry2[num2]。其中num是存在的条目数，num2是随机生成的rand（）数。然后我想让它检查新条目是否至少比旧条目多15个位置（在这种情况下..因此骑手可以在下一个事件之前休息）

所以你可以猜到。。这个应用程序不起作用，我猜有更简单的方法吗？ 如何将变量发送到此数组中，以及如何使此函数将数组返回到我的主。。我是通过指针猜的

我在下面附上了全部代码
