c - if语句和for()在C中具有结构的函数中循环

我知道这是一个非常新手的问题，但是我在程序中的if和for（）循环遇到了麻烦。我试图指定问题的出处，但基本上是在main（）中询问用户是否要解雇一名雇员，然后询问该雇员ID。然后在dismissWorker函数中，应该扫描工作者ID的数组，找到与要解雇的雇员匹配的ID（badID），然后更改该数组。在我的dismissWorker函数中，我打印了“ HI”，只是为了查看我是否在main中正确调用了它（确实如此），但它没有通过for（）循环运行。我确定我做错了很简单，但这到底是什么呢？另外，我不知道在dismissWorker结束时应该返回什么内容，因此一些建议会有所帮助。

最佳答案

在函数initWorkerArray(workerT list[], int siz)中，启动四个workerT对象，这些对象的empID值为1、2、6、7。

现在，在main函数中，用dismissWorker调用dismissWorker(roster, MAX_ROSTER, 10)

在for循环中：

for (i = 0; i < siz; ++i) { //FIXME
    if (list[i].empID == badID) {
        printf("HIHIHI");
        list[i].empStatus = -1;
        list[i].month100_paycheck = 0;
        list[i].year100_salary = 0;
    return 1;
    }
}

据我所知，代码确实在for循环中运行，但是找不到badID并退出。您应该打印警告或错误消息以捕获诸如此类的错误。

尝试dismissWorker(roster, MAX_ROSTER, 7)进行测试。它应该可以工作，并使用错误/警告消息来捕获代码中无法预料的情况，例如在这种情况下不存在的empID。俗称Defensive Programming
