Output MP3 contents as binary/hexadecimal [message #1833206] Tue, 06 October 2020 14:17 Go to next message

I am fairly new to C++ and Eclipse.

I figured out how to open an MP3 file and output the contents of the file to the console, but it is displayed in a coded format. I am trying to look for patterns so I need the fstream to be binary (or hexadecimal is fine). When I output the content of the fstream to the console I get:

File is open!
ID3 bTIT2 Stupid Song

(Truncated for simplification)

What I expect is what I see when I open the mp3 in a hex editor:

33 03 00 00 00 01 09 62 54 49 54 32 00 00
00 00 00 52 74 75 70 69 64 20 53 6F 6E 67

What am I doing wrong? Is it a console setting, an issue with it being a string? Something else entirely? Thanks for your help!

Are you sure your post isn't merely a post intended to attach an *.mp3 file? In any case, your post isn't asking how to use Eclipse's tools but rather how to program in C/C++. It appears to me that you're reading a binary file and hoping to print it out in hex, but I'm not sure what makes you think hex should be printed just by reading a line from a binary file. Perhaps try a more general forum such as stackoverflow for general programming questions.
