Ofstream::write adding extra bytes to the end of file

I'm trying to write the following bytes to a file [03 00 01 00 FF 00 00 00 FF 00 00 00 FF] but I keep getting the following bytes added to the end [03 01 0F C0 00 08 00 A0 00 C7 00 00 00 02 00 70 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00] I've read up, and I've been told to use std::ios::binary when opening the file, which doesn't seem to help Here's my code

#include <fstream> 
#include <iostream>
#include <conio.h>
#include <iomanip>

using namespace std;

int main() {
    int height = 1,
        length = 3;
    int data[] = {
        0x3,0x0,0x1,0x0,
        0xff, 0x0, 0x0,
        0x0, 0xff, 0x0,
        0x0, 0x0, 0xff
    };

    ofstream file("thing.dki", std::ios::binary);
    for(int i = 0; i < sizeof(data); i++) {
        file.write((char*) &data[i], 1);
    }
    file.close();

    return 0;
}
