少数事情：
如果菜单无法正常工作，则可能会保留未初始化的值。
您应真正检查scanf的返回值。此外，您需要在调用scanf后清除输入缓冲区。 char ch = getchar(); while (ch != EOF && ch != '\n') ch = getchar();。
我不认为你正在编写警告;你应该。例如，currentEmployee;绝对没有任何作用。
在editEmployee内，您只传递一名员工。更好的方法是按值payroll 按值传递。数组将通过指针隐式传递元素 - 如果更改其中一个数组索引的值而不更改数组指向的位置，则该更改将在程序中反映出来返回主页。
您应该在 employeeInfo的末尾调用 计算。现在，它不会被召唤一次。
您应该正确地将payroll初始化为实际值;否则，计算结果未定义。此外，`计算（＆amp; payroll）是完全错误的，因为应该传递一个指向数组的指针，这显然不是你想要的。 （程序如何编译？）

起初
struct person payroll[5] = { 0 };
int choice = 0, currentEmployee = 0;
这里你声明了5个结构的数组。而不是
calculations(&payroll);
你应该使用
calculations(&payroll[0]);
或
calculations(payroll);
将指针传递给数组的第一个元素
变量currentEmployee不会更改。这条线什么都不做
currentEmployee;
此外，您的代码还包含许多其他问题。您应该在C中了解有关指针和数组的更多信息。
