Question

I have the following code (C++)

vector<unsigned char> bytes;
bytes.push_back('e');
bytes.push_back('P');
bytes.push_back('R');
bytes.push_back('f');

...

ofstream file(compiledFile, ios::out | ios::binary);
file.write((const char*) &binary[0], binary.size());
file.close();

but as a result is output file I have
“rPRf”
instead of bytes.

What I’m doing wrong? I need “65505266” bytes as a result.

Thank you all.

Answer 1

e, P, R and f are bytes. The file is 4 characters (bytes) long and it contains what you put there.

The only difference between a “binary file” and a “text file” is how linebreaks are read/written on Windows (and maybe some other special characters on very old OSes). The only difference between the character e and the number 65 is how the program that you’re using to read the file chooses to display it. A text editor will display e and a hex editor will display 65.
