客户消费积分管理系统c语言顺序表源代码

好的，以下是一个简单的客户消费积分管理系统的 C 语言顺序表源代码示例：

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

#define MAX_LENGTH 20
#define MAX_CUSTOMERS 100

typedef struct {
    char name[MAX_LENGTH];
    int points;
} Customer;

typedef struct {
    Customer customers[MAX_CUSTOMERS];
    int length;
} CustomerList;

void init_list(CustomerList *list) {
    list->length = 0;
}

void add_customer(CustomerList *list, char *name, int points) {
    if (list->length < MAX_CUSTOMERS) {
        strcpy(list->customers[list->length].name, name);
        list->customers[list->length].points = points;
        list->length++;
        printf("Customer added successfully\n");
    } else {
        printf("Customer list is full\n");
    }
}

int find_customer(CustomerList *list, char *name) {
    for (int i = 0; i < list->length; i++) {
        if (strcmp(list->customers[i].name, name) == 0) {
            return i;
        }
    }
    return -1;
}

void add_points(CustomerList *list, char *name, int points) {
    int index = find_customer(list, name);
    if (index != -1) {
        list->customers[index].points += points;
        printf("%d points added to customer %s\n", points, name);
    } else {
        printf("Customer %s not found\n", name);
    }
}

void subtract_points(CustomerList *list, char *name, int points) {
    int index = find_customer(list, name);
    if (index != -1) {
        if (list->customers[index].points >= points) {
            list->customers[index].points -= points;
            printf("%d points subtracted from customer %s\n", points, name);
        } else {
            printf("Customer %s does not have enough points\n", name);
        }
    } else {
        printf("Customer %s not found\n", name);
    }
}

void print_list(CustomerList *list) {
    printf("Customer List:\n");
    for (int i = 0; i < list->length; i++) {
        printf("%s - %d points\n", list->customers[i].name, list->customers[i].points);
    }
}

int main() {
    CustomerList list;
    init_list(&list);

    add_customer(&list, "Alice", 100);
    add_customer(&list, "Bob", 200);
    add_customer(&list, "Charlie", 300);

    add_points(&list, "Alice", 50);
    subtract_points(&list, "Bob", 100);
    add_points(&list, "Dave", 50);

    print_list(&list);

    return 0;
}

该程序定义了 `Customer` 结构体和 `CustomerList` 结构体，分别表示单个客户和客户列表。程序中定义了 `init_list`、`add_customer`、`find_customer`、`add_points`、`subtract_points` 和 `print_list` 函数，用于初始化列表、添加客户、查找客户、添加积分、减少积分和打印列表。

在 `main` 函数中，我们先初始化了客户列表，然后添加了几个客户，接着对其中一些客户添加或减少了积分，最后打印了整个客户列表。

该程序只是一个简单示例，您可以在此基础上进行扩展，实现更多功能。
