C++ :: Printing Out Bytes Of A File

I am encoding some information in a binary file, and I want to check what I am doing by printing out all the bytes that represent the file.

This is being done by opening a pointer to the file with fopen, reading in each byte of data as a char, and then writing this char to the screen.

I have some image files (e.g. "image.jpg"), whose structure I know, so that I can test my program.

When I print out the chars, they are initially correct, and follow the structure of the file as expected.

However, after about 40 bytes, I find that every subsequent character is ' ' i.e. a blank character.

I then created a CharToBin function, which allows me to print out the actual bits in the char. When doing this, it shows that all the bits are 1 for the characters. i.e. most of the file is represented by 1's, which is clearly not correct.

This happens on all the image files I have tested, and furthermore, on several other non-image files. They all start printing out ' ' after a while. However, all these files are fine and not corrupted, e.g. the image files display correctly.

Code:
#include <fstream>
#include <iostream>
#include <sstring>
#include <string>
#include <stdio.h>
using namespace std;
string CharToBin(char ch) {
bool bits[8];
for (int i = 0; i < 8; i++)
