用C语言中的顺序表编写完成用电情况信息的查询（按照企业编号和企业名称）、更新、插入、删除、排序等功能。（其中包含了，编号、企业编号、企业名称、联系电话、谷电量、峰电量、谷价、峰价、年月、合计电量、合计电费等信息）

很抱歉，C语言中没有内置的顺序表数据结构，需要自己实现。下面是一个示例代码，仅供参考。

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

#define MAX_RECORDS 1000 // 最大记录数

// 电力用量记录
typedef struct {
    int id; // 记录编号
    int enterprise_id; // 企业编号
    char enterprise_name[50]; // 企业名称
    char phone[20]; // 联系电话
    int valley_amount; // 谷电量
    int peak_amount; // 峰电量
    float valley_price; // 谷价
    float peak_price; // 峰价
    int year_month; // 年月
    int total_amount; // 合计电量
    float total_price; // 合计电费
} Record;

// 顺序表
typedef struct {
    Record* data[MAX_RECORDS]; // 记录指针数组
    int length; // 当前记录数
} SeqList;

// 初始化顺序表
void init(SeqList* list) {
    list->length = 0;
}

// 按照企业编号和企业名称查找记录
Record* search(SeqList* list, int enterprise_id, char* enterprise_name) {
    for (int i = 0; i < list->length; i++) {
        Record* record = list->data[i];
        if (record->enterprise_id == enterprise_id && strcmp(record->enterprise_name, enterprise_name) == 0) {
            return record;
        }
    }
    return NULL;
}

// 更新记录
void update(SeqList* list, int id, int enterprise_id, char* enterprise_name, char* phone, int valley_amount, int peak_amount, float valley_price, float peak_price, int year_month, int total_amount, float total_price) {
    Record* record = list->data[id - 1];
    record->enterprise_id = enterprise_id;
    strcpy(record->enterprise_name, enterprise_name);
    strcpy(record->phone, phone);
    record->valley_amount = valley_amount;
    record->peak_amount = peak_amount;
    record->valley_price = valley_price;
    record->peak_price = peak_price;
    record->year_month = year_month;
    record->total_amount = total_amount;
    record->total_price = total_price;
}

// 插入记录
void insert(SeqList* list, int enterprise_id, char* enterprise_name, char* phone, int valley_amount, int peak_amount, float valley_price, float peak_price, int year_month, int total_amount, float total_price) {
    if (list->length >= MAX_RECORDS) {
        printf("ERROR: The list is full!\n");
        return;
    }
    Record* record = (Record*)malloc(sizeof(Record));
    record->id = list->length + 1;
    record->enterprise_id = enterprise_id;
    strcpy(record->enterprise_name, enterprise_name);
    strcpy(record->phone, phone);
    record->valley_amount = valley_amount;
    record->peak_amount = peak_amount;
    record->valley_price = valley_price;
    record->peak_price = peak_price;
    record->year_month = year_month;
    record->total_amount = total_amount;
    record->total_price = total_price;
    list->data[list->length] = record;
    list->length++;
}

// 删除记录
void del(SeqList* list, int id) {
    if (id < 1 || id > list->length) {
        printf("ERROR: Invalid id!\n");
        return;
    }
    Record* record = list->data[id - 1];
    free(record);
    for (int i = id - 1; i < list->length - 1; i++) {
        list->data[i] = list->data[i + 1];
        list->data[i]->id--;
    }
