초보입니다..
요걸 fstream을 사용해 C++스타일로 바꾸려는 중인데요..
밑과 같이 바꿨는데 런타임 에러가 발생합니다. 왜그런걸까요 ㅠ.ㅠ

file = person.bin;
FILE *fpr;

fpr = fopen(file,rb);
if(!fpr) {
cout Person.bin FILE DOES NOT EXIST OR DAMAGED. endl;
exit(1);
}
fseek(fpr,0L,SEEK_END);
total_block = ftell(fpr) / sizeof(person); // number of members
fseek(fpr,0L,SEEK_SET);
d = (person*)malloc(sizeof(person)*total_block);
fread(d,sizeof(person),total_block,fpr);
fclose(fpr);

fstream fpr(person.bin, ios::in | ios::out | ios::binary);
if(!fpr) {
cout Person.bin FILE DOES NOT EXIST OR DAMAGED. endl;
exit(1);
}
fpr.seekp(0, ios::end);
total_block = (fpr.tellg() / sizeof(person));
fpr.seekp(0, ios::beg);
d = new person[sizeof(person) * total_block];
fpr.read((char *)&d, total_block);
fpr.close();
