C数据库。没有完全填满二进制文件

我有一个data.txt文件，我用制表符分隔每个字段。我从文件中读取变量，然后写入二进制文件。问题是二进制文件没有完全填充。

person_dump.c：

#include <stdio.h>
#include <string.h>
#include <errno.h>
#include "person.h"

int readperson(person *p){
        return scanf("%[^\t]\t%d\t%[^\t]\t%d\t%[^\t]\t%d\t%[^\t]\t%d\t%d\t%d\t%[^\t]\n",
        p->Name,&p->NumCPU,p->TypeCPU,&p->SizeRAM,p->TypeGPU,&p->SizeGPU,p->TypeHDD,&p->NumHDD,&p->SizeHDD,&p-> Peripheral,p->NameOS);
}

int main(int argc, char* argv[]){
        person p;
        FILE *out = fopen(argv[1],"w");
        if(!out){
                perror("Can't open file");
                return 2;
        }
        while(readperson(&p)){
                fwrite(&p,sizeof(p), 1,out);
                return 0;
        }
}

人.h：

#ifndef __person_h__
#define __person_h__
typedef struct{
        char Name[50];
        int NumCPU;
        char TypeCPU[50];
        int SizeRAM;
        char TypeGPU[50];
        int SizeGPU;
        char TypeHDD[50];
        int NumHDD;
        int SizeHDD;
        int Peripheral;
        char NameOS[50];
} person;
#endif
