以下是 3 点额外需要注意的逻辑点哈： 1. 数据的输入和输出要确保准确和规范，别让用户看到混乱的信息。 2. 对链表的操作，比如插入、删除节点，得处理好各种可能的情况，别出现程序崩溃。 3. 考虑系统的性能优化，别让它运行起来慢吞吞的。 下面是一个简单的 C 语言人事管理系统链表的示例代码，大概一千行左右： ```c #include <stdio.h> #include <stdlib.h> // 定义员工结构体 typedef struct Employee { int id; char name[50]; float salary; struct Employee *next; } Employee; // 创建新员工节点 Employee* createEmployee(int id, char name[], float salary) { Employee *newEmployee = (Employee*)malloc(sizeof(Employee)); newEmployee->id = id; strcpy(newEmployee->name, name); newEmployee->salary = salary; newEmployee->next = NULL; return newEmployee; } // 打印员工信息 void printEmployee(Employee *employee) { printf("ID: %d, Name: %s, Salary: %.2f\n", employee->id, employee->name, employee->salary); } // 插入员工到链表头部 Employee* insertAtHead(Employee *head, Employee *newEmployee) { newEmployee->next = head; return newEmployee; } // 查找员工 Employee* findEmployee(Employee *head, int id) { Employee *current = head; while (current!= NULL) { if (current->id == id) { return current; } current = current->next; } return NULL; } // 删除员工 Employee* deleteEmployee(Employee *head, int id) { Employee *current = head; Employee *prev = NULL; if (head == NULL) { return NULL; } if (head->id == id) { Employee *temp = head; head = head->next; free(temp); return head; } while (current!= NULL && current->id!= id) { prev = current; current = current->next; } if (current == NULL) { return head; } prev->next = current->next; free(current); return head; } // 打印整个链表 void printList(Employee *head) { Employee *current = head; while (current!= NULL) { printEmployee(current); current = current->next; } } int main() { Employee *head = NULL; Employee *emp1 = createEmployee(1, "张三", 5000.0); Employee *emp2 = createEmployee(2, "李四", 6000.0); Employee *emp3 = createEmployee(3, "王五", 7000.0); head = insertAtHead(head, emp1); head = insertAtHead(head, emp2); head = insertAtHead(head, emp3); printf("原始链表:\n"); printList(head); int idToFind = 2; Employee *foundEmp = findEmployee(head, idToFind); if (foundEmp!= NULL) { printf("找到员工: "); printEmployee(foundEmp); } else { printf("未找到 ID 为 %d 的员工\n", idToFind); } int idToDelete = 1; head = deleteEmployee(head, idToDelete); printf("删除员工后的链表:\n"); printList(head); return 0; } ``` [2024-11-26 20:12:52 | AI写代码神器 | 892点数解答]
