    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Can you open and close the file?
    Can you write the code to Hex Dump the data?
    If you can do these things, then we don't need to tell you about how to open/read/close files, because you can do that much yourself.

    Have you written any code to deal with declaring a matrix?
    - as a 2D array (C style)
    - as a vector<vector> of some type (C++ style)
    If you can do these things, then we don't need to tell you about these either

    Which kind of image file is it? There are many -> Image file formats - Wikipedia, the free encyclopedia

    In other words, you need to write some code up to the point you get stuck, and then ask a specific question about what happens next.

    I studied techniques programming
    I can open and write the text file, do operation on 2d array...
    I want to read an image as *.jpg,..
    I will write the code in c++, when I added a path of image file, then I press enter, It's show 2d array as interger about information of it.
    Finally, I will use it for some other case.

    Upgrade your IDE.

    Then you'll want to use a library to do all the low-level math (or high-level math, depending on your point of view).
