请问个关于fwrite之类的问题。。。。

[accome]

void CreatFile()
{

FILE *fp;
struct YuanGong yg;
fp=fopen("yg.dat","ab+");
cout<<"员工序号：";
cin>>yg.Numb;
cout<<"员工姓名：";
cin>>yg.Name;
fwrite(&yg,sizeof(struct YuanGong),1,fp);
fclose(fp);
}


void ChaXun()
{
struct YuanGong yg,yg1;
FILE *qp;
qp=fopen("yg.dat","rb+");
cout<<"请输入序号：";
cin>>yg.Numb;
rewind(qp);
while(fread(&yg1,sizeof(struct YuanGong),1,qp))
{
if(strcmp(yg.Numb,yg1.Numb)==0)
cout<<yg.Numb <<yg.Name ;
}
fclose(qp);
};


为什么输出第一个yg.Numb是对的，但是yg,Name是乱码了..全是什么烫烫烫。。。。郁闷死了。。。。。请教高手改改。。。。

楼主可以按照下面的尝试下：
void CreatFile()
{

FILE *fp;
char str[100];
struct YuanGong yg;

if(NULL == (fp=fopen("yg.txt","a+")))
{
return;
}

cout<<"员工序号:";
cin>>yg.Numb;
cout<<"员工姓名:";
cin>>yg.Name;
sprintf(str,"%d,%s",yg.Numb,yg.Name);

fwrite(str,strlen(str),1,fp);
fwrite("\n",sizeof("\n"),1,fp);

fclose(fp);
}

fwrite(&yg,sizeof(struct YuanGong),1,fp);
引起的吧
你不用结构使用成员fwrite试试

[hhyttppd]

void CreatFile()
{

FILE *fp;
struct YuanGong yg;
//加一句
memset(&yg, 0, sizeof(YuanGong ));
fp=fopen("yg.dat","ab+");
cout < <"员工序号：";
cin>>yg.Numb;
cout < <"员工姓名：";
cin>>yg.Name;
fwrite(&yg,sizeof(struct YuanGong),1,fp);
fclose(fp);
}
