物业费管理系统c语言链表

以下是一个简单的物业费管理系统的C语言链表实现：

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

#define MAX_NAME_LEN 20

typedef struct PropertyFee {
    char name[MAX_NAME_LEN];
    int fee;
    struct PropertyFee* next;
} PropertyFee;

void addPropertyFee(PropertyFee** head, char* name, int fee) {
    PropertyFee* newPropertyFee = (PropertyFee*)malloc(sizeof(PropertyFee));
    strncpy(newPropertyFee->name, name, MAX_NAME_LEN);
    newPropertyFee->fee = fee;
    newPropertyFee->next = NULL;

    if (*head == NULL) {
        *head = newPropertyFee;
    } else {
        PropertyFee* cur = *head;
        while (cur->next != NULL) {
            cur = cur->next;
        }
        cur->next = newPropertyFee;
    }
}

void printPropertyFee(PropertyFee* propertyFee) {
    printf("%s: %d\n", propertyFee->name, propertyFee->fee);
}

void printPropertyFeeList(PropertyFee* head) {
    PropertyFee* cur = head;
    while (cur != NULL) {
        printPropertyFee(cur);
        cur = cur->next;
    }
}

void freePropertyFeeList(PropertyFee* head) {
    PropertyFee* cur = head;
    while (cur != NULL) {
        PropertyFee* next = cur->next;
        free(cur);
        cur = next;
    }
}

int main() {
    PropertyFee* head = NULL;
    addPropertyFee(&head, "A", 100);
    addPropertyFee(&head, "B", 200);
    addPropertyFee(&head, "C", 300);

    printPropertyFeeList(head);

    freePropertyFeeList(head);
    head = NULL;

    return 0;
}

这个程序定义了一个`PropertyFee`结构体，包含了物业费的名称和金额，以及一个指向下一个物业费的指针。`addPropertyFee`函数将新的物业费添加到链表的末尾，`printPropertyFeeList`函数遍历整个链表并打印出每个物业费的名称和金额，`freePropertyFeeList`函数释放链表中的所有内存。在主函数中，我们创建一个空链表，添加三个物业费，打印出整个链表，然后释放链表中的所有内存。

当然，这只是一个非常简单的示例，实际的物业费管理系统可能需要更多的功能和复杂的逻辑。
