How to split an array containing an entire file (.exe/.jpg/.avi/.docx etc) into rows of a 2 dimensional matrix (2d array).
This is just to apply some cipher (encryption) operations.

You have already asked this question at Encrypting a binary file.[^].

However, a file is just a stream of bytes, so you just need to read it into a byte array and then manipulate the contents according to your requirements. The standard CRT library fread function[^], or the Windows ReafFile function[^], will do what you want.

But does it take the data into a 2 d array. It will only place the data into a linear array.

No, the I/O functions are designed to read data into a 1d linear array. If you want it in 2d then you have to write the code to do it. That's what being a developer is all about.
