Reading a struct from a file (binary)

[Trebeki]

Hey.

I have a file in which I have written a structure called "Record".
Here is the struct definition:

#define IDSIZE 10
struct Record{
	char id[IDSIZE];
	int score;
};

Here's the code where I wrote to the file:

Record record;
char* id = "H12345678";
int score = 50;
record.id = id;
record.score = score;
file.write((const char*)&record, sizeof(record));
}

Here's a screenshot of the file in windows:

To the left is the id, 9 characters.
To the right, well I'm assuming that's the score that I wrote.

And here's the problem, reading from the binary file:

  Record record;

	fstream file(argv[1], ios::in | ios::binary);
	if(!file){
		cerr << "Could not open the file." << endl;
		return 1;
	}
	char* id = new char[IDSIZE];
	char* buff = new char[100]; //buffer to hold the string representation of the score
	file.seekg(0, ios::beg);
	file.read(id, IDSIZE);
	cout << "ID: " << id << endl;
	file.read(buff, sizeof(int));
	int score = atoi(buff);
	cout << "SCORE: " << score << endl;
	file.clear();
	file.close();
	return 0;

The ID reads perfectly.
The score...always returns 0, despite that it should show "50".

record.id = id; //error: incompatible types in assignment of ‘char*’ to ‘char [10]’

> buffer to hold the string representation of the score
wrong, `buffer' does not contain {'5','0','\0'} so it cannot be converted with `atoi()'
