Check first 2 bytes?

Question

C++ / C#

Hello. For example, there is a file, I open it. But how do I represent it in binary form so that I can read the first 2 bytes from it? To be specific, I need to compare the first 2 bytes with 0x4D 0x5A. Googled, but still did not understand how to convert the file that I receive through CreateFile () into an array of bytes

Answer 1

Open the file in ifstream in binary mode and read 2 bytes with read .
Or use fread . Read 2 bytes into a buffer of length 2.
