请写一段以C语言为基础的通讯录管理系统要求如下⑴ 添加和删除通讯录中的记录信息； ⑵ 浏览通讯录信息； ⑶ 根据姓名进行查询。 ⑷ 统计排序，统计某籍贯的所有学生数量并排序。 ⑸ 结果格式化显示。并且可以在vs2010中运行

好的，以下是一个简单的通讯录管理系统的C语言代码，可以在VS2010中运行：

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

#define MAX_NAME_LEN 20
#define MAX_ADDRESS_LEN 50
#define MAX_PHONE_LEN 15
#define MAX_STUDENT_NUM 100

// 定义学生结构体
typedef struct {
    char name[MAX_NAME_LEN];
    char address[MAX_ADDRESS_LEN];
    char phone[MAX_PHONE_LEN];
} Student;

// 定义通讯录结构体
typedef struct {
    Student students[MAX_STUDENT_NUM];
    int num_students;
} AddressBook;

// 添加学生信息
void add_student(AddressBook *book) {
    if (book->num_students >= MAX_STUDENT_NUM) {
        printf("通讯录已满，无法添加学生信息！\n");
        return;
    }
    Student *new_student = &(book->students[book->num_students]);
    printf("请输入学生姓名：");
    scanf("%s", new_student->name);
    printf("请输入学生地址：");
    scanf("%s", new_student->address);
    printf("请输入学生电话：");
    scanf("%s", new_student->phone);
    book->num_students++;
    printf("学生信息添加成功！\n");
}

// 删除学生信息
void remove_student(AddressBook *book) {
    if (book->num_students == 0) {
        printf("通讯录中没有学生信息！\n");
        return;
    }
    char name[MAX_NAME_LEN];
    printf("请输入要删除的学生姓名：");
    scanf("%s", name);
    int i = 0;
    for (; i < book->num_students; i++) {
        if (strcmp(name, book->students[i].name) == 0) {
            break;
        }
    }
    if (i == book->num_students) {
        printf("通讯录中没有该学生信息！\n");
        return;
    }
    book->num_students--;
    for (; i < book->num_students; i++) {
        book->students[i] = book->students[i+1];
    }
    printf("学生信息删除成功！\n");
}

// 浏览学生信息
void browse_students(AddressBook *book) {
    if (book->num_students == 0) {
        printf("通讯录中没有学生信息！\n");
        return;
    }
    printf("姓名\t地址\t电话\n");
    for (int i = 0; i < book->num_students; i++) {
        printf("%s\t%s\t%s\n", book->students[i].name, book->students[i].address, book->students[i].phone);
    }
}

// 根据姓名查询学生信息
void find_student(AddressBook *book) {
    if (book->num_students == 0) {
        printf("通讯录中没有学生信息！\n");
        return;
    }
    char name[MAX_NAME_LEN];
    printf("请输入要查询的学生姓名：");
    scanf("%s", name);
    for (int i = 0; i < book->num_students; i++) {
        if (strcmp(name, book->students[i].name) == 0) {
            printf("姓名\t地址\t电话\n");
            printf("%s\t%s\t%s\n", book->students[i].name, book->students[i].address, book->students[i].phone);
            return;
        }
    }
    printf("通讯录中没有该学生信息！\n");
}

// 统计排序学生信息
void sort_students(AddressBook *book) {
    if (book->num_students == 0) {
        printf("通讯录中没有学生信息！\n");
        return;
    }
    char address[MAX_ADDRESS_LEN];
    printf("请输入要统计排序的籍贯：");
    scanf("%s", address);
    int count = 0;
    Student temp;
    for (int i = 0; i < book->num_students; i++) {
        if (strcmp(address, book->students[i].address) == 0) {
            count++;
            for (int j = i+1; j < book->num_students; j++) {
                if (strcmp(address, book->students[j].address) == 0) {
                    if (strcmp(book->students[i].name, book->students[j].name) > 0) {
                        temp = book->students[i];
                        book->students[i] = book->students[j];
                        book->students[j] = temp;
                    }
                }
            }
        }
    }
    printf("共计%d个%s籍贯的学生，按姓名排序结果如下：\n", count, address);
    printf("姓名\t地址\t电话\n");
    for (int i = 0; i < book->num_students; i++) {
        if (strcmp(address, book->students[i].address) == 0) {
            printf("%s\t%s\t%s\n", book->students[i].name, book->students[i].address, book->students[i].phone);
        }
    }
}

// 格式化显示学生信息
void format_students(AddressBook *book) {
    if (book->num_students == 0) {
        printf("通讯录中没有学生信息！\n");
        return;
    }
    printf("姓名\t\t地址\t\t\t电话\n");
    for (int i = 0; i < book->num_students; i++) {
        printf("%-20s%-30s%-15s\n", book->students[i].name, book->students[i].address, book->students[i].phone);
    }
}

int main() {
    AddressBook book;
    book.num_students = 0;
    int choice = 0;
    while (1) {
        printf("请选择操作：\n");
        printf("1. 添加学生信息\n");
        printf("2. 删除学生信息\n");
        printf("3. 浏览学生信息\n");
        printf("4. 根据姓名查询学生信息\n");
        printf("5. 统计排序学生信息\n");
        printf("6. 格式化显示学生信息\n");
        printf("7. 退出\n");
        scanf("%d", &choice);
        switch (choice) {
            case 1:
                add_student(&book);
                break;
            case 2:
                remove_student(&book);
                break;
            case 3:
                browse_students(&book);
                break;
            case 4:
                find_student(&book);
                break;
            case 5:
                sort_students(&book);
                break;
            case 6:
                format_students(&book);
                break;
            case 7:
                printf("谢谢使用！\n");
                exit(0);
            default:
                printf("输入错误，请重新输入！\n");
        }
    }
    return 0;
}

以上就是一个简单的以C语言为基础的通讯录管理系统的代码，可以实现添加、删除、浏览、查询、统计排序和格式化显示学生信息的功能。
