how to copy binary data of a file - c++

Question

Basically, I am trying to read binary data of a file by using fread() and print it on screen using printf(), now, the problem is that when it prints it out, it actually don't show it as binary 1 and 0 but printing symbols and stuff which I don't know what they are.
This is how I am doing it:
#include <stdio.h>
#include <windows.h>
int main(){
size_t sizeForB, sizeForT;
char ForBinary[BUFSIZ], ForText[BUFSIZ];
char RFB [] = "C:\\users\\(Unknown)\\Desktop\\hi.mp4" ; // Step 1
FILE *ReadBFrom = fopen(RFB , "rb" );
if(ReadBFrom == NULL){
printf("Following File were Not found: %s", RFB);
return -1;
} else {
printf("Following File were found: %s\n", RFB); // Step 2
while(sizeForB = fread(ForBinary, 1, BUFSIZ, ReadBFrom)){ // Step 1
printf("%s", ForBinary);
}
fclose(ReadBFrom);
}
return 0;
}
I would really appreciate if someone could help me out to read the actual binary data of a file as binary (0,1).

Answer 1

while(sizeForB = fread(ForBinary, 1, BUFSIZ, ReadBFrom)){
printf("%s", ForBinary); }
This is wrong on many levels. First of all you said it is binary file - which means there might not be text in it in the first place, and you are using %s format specifier which is used to print null terminated strings. Again since this is binary file, and there might not be text in it in the first place, %s is the wrong format specifier to use. And even if there was text inside this file, you are not sure that fread would read a "complete" null terminated string that you could pass to printf with format specifier %s.
What you may want to do is, read each byte form a file, convert it to a binary representation (google how to convert integer to binary string say, e.g., here), and print binary representation for each that byte.
Basically pseudocode:
foreach (byte b in FileContents)
{
string s = convertToBinary(b);
println(s);
}

How to view files in binary in the terminal?
Either
"hexdump -C yourfile.bin" perhaps, unless you want to edit it of course. Most linux distros have hexdump by default (but obviously not all).
or
xxd -b file

To simply read a file and print it in binary (ones and zeros), read it one char at a time. Then for each bit, print a '0' or '1'. Can print Most or Least significant bit first. Suggest MSb.
if (ReadBFrom) {
int ch;
while ((ch = fgetc(ReadBFrom)) != EOF) {
unsigned mask = 1u << (CHAR_BIT - 1); // CHAR_BIT is typically 8
while (mask) {
putchar(mask & ch ? '1' : '0');
mask >>= 1;
}
}
fclose(ReadBFrom);
}
