要求用C语言编写:1.先编写一个带结构的文件，存入电脑，要求第一行从左到右的内容依次是：序号、姓名、学号、地址，每排每列对齐，没有对齐的地方用空格补齐。2.从电脑中能够读入这个带结构的文件，并进行删增改后，重新存入电脑，3.这个文件要有纵横结构，每横表示一个记录4. 编出来的代码要能够在c的运行界面进行后续的插入、删除和修改

好的，我来简单介绍一下这个问题的解决思路：

1. 首先，需要定义一个结构体来表示每个记录的信息，包括序号、姓名、学号、地址等字段；
2. 然后，需要编写读取文件的函数，可以使用C标准库中的文件操作函数，比如fopen、fread等；
3. 接着，可以使用链表或数组等数据结构来存储文件中的记录信息，并实现插入、删除和修改等操作；
4. 最后，需要编写写入文件的函数，将修改后的记录重新写入文件中。

下面是一个简单的实现示例：

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

#define MAX_LEN 100

//定义记录结构体
typedef struct Record{
    int id;
    char name[MAX_LEN];
    char number[MAX_LEN];
    char address[MAX_LEN];
    struct Record *next;
} Record;

//读取文件中的记录
Record* readRecords(char* filename){
    FILE *fp = fopen(filename, "r");
    if(fp == NULL){
        printf("Failed to open file %s", filename);
        return NULL;
    }

    Record *head = NULL, *tail = NULL;
    char line[MAX_LEN];
    fgets(line, MAX_LEN, fp);//读取第一行，但不做处理
    while(fgets(line, MAX_LEN, fp) != NULL){
        Record *record = (Record*)malloc(sizeof(Record));
        sscanf(line, "%d%s%s%s", &(record->id), record->name, record->number, record->address);
        record->next = NULL;
        if(head == NULL){
            head = tail = record;
        }else{
            tail->next = record;
            tail = record;
        }
    }

    fclose(fp);
    return head;
}

//在链表中添加新记录
Record* addRecord(Record *head, Record *newRecord){
    if(head == NULL){
        return newRecord;
    }
    Record *p = head;
    while(p->next != NULL){
        p = p->next;
    }
    p->next = newRecord;
    return head;
}

//从链表中删除某个记录
Record* deleteRecord(Record *head, int id){
    if(head == NULL){
        return NULL;
    }
    Record *p = head, *pre = NULL;
    while(p != NULL){
        if(p->id == id){
            if(pre == NULL){
                head = p->next;
            }else{
                pre->next = p->next;
            }
            free(p);
            return head;
        }
        pre = p;
        p = p->next;
    }
    return head;
}

//修改链表中某个记录的信息
Record* modifyRecord(Record *head, int id, Record *newRecord){
    if(head == NULL){
        return NULL;
    }
    Record *p = head;
    while(p != NULL){
        if(p->id == id){
            strcpy(p->name, newRecord->name);
            strcpy(p->number, newRecord->number);
            strcpy(p->address, newRecord->address);
            return head;
        }
        p = p->next;
    }
    return head;
}

//将链表中的记录写入文件
void writeRecords(char *filename, Record *head){
    FILE *fp = fopen(filename, "w");
    if(fp == NULL){
        printf("Failed to open file %s", filename);
        return;
    }
    fprintf(fp, "%-10s%-20s%-20s%-20s\n", "序号", "姓名", "学号", "地址");//写入第一行
    Record *p = head;
    while(p != NULL){
        fprintf(fp, "%-10d%-20s%-20s%-20s\n", p->id, p->name, p->number, p->address);
        p = p->next;
    }
    fclose(fp);
}

//打印链表中的记录
void printRecords(Record *head){
    printf("%-10s%-20s%-20s%-20s\n", "序号", "姓名", "学号", "地址");//打印第一行
    Record *p = head;
    while(p != NULL){
        printf("%-10d%-20s%-20s%-20s\n", p->id, p->name, p->number, p->address);
        p = p->next;
    }
}

int main(){
    Record *head = readRecords("records.txt");
    if(head == NULL){
        return 0;
    }
    printRecords(head);

    //添加新记录
    Record *newRecord = (Record*)malloc(sizeof(Record));
    newRecord->id = 4;
    strcpy(newRecord->name, "张三");
    strcpy(newRecord->number, "20210004");
    strcpy(newRecord->address, "北京市海淀区");
    head = addRecord(head, newRecord);
    printf("After adding new record:\n");
    printRecords(head);

    //删除记录
    head = deleteRecord(head, 2);
    printf("After deleting record with id=2:\n");
    printRecords(head);

    //修改记录
    Record *modifiedRecord = (Record*)malloc(sizeof(Record));
    modifiedRecord->id = 1;
    strcpy(modifiedRecord->name, "王五");
    strcpy(modifiedRecord->number, "20210001");
    strcpy(modifiedRecord->address, "上海市浦东新区");
    head = modifyRecord(head, 1, modifiedRecord);
    printf("After modifying record with id=1:\n");
    printRecords(head);

    //将修改后的记录写入文件
    writeRecords("records.txt", head);

    return 0;
}

在这个示例中，我们使用了链表来存储记录信息，并实现了添加、删除和修改等操作。同时，我们还编写了读取和写入文件的函数，可以将记录信息存储在文件中，并在需要时重新读取和修改。
