First introduce the idea of program implementation in words, and then paste the code on paper. If the code is too long, it is undoubtedly not suitable for direct copy and paste. You can choose to use pseudo code to describe the implementation process of your own program, and you can use ellipsis to omit the unimportant code in the middle and only write the processing of key logic. It is not recommended to paste code pictures, because there may be scaling problems in the pictures, resulting in blurred fonts. At the same time, typesetting and font format may be affected. I don't know what your tutor and reviewers will think, but my paper was typed back because several letters were in the wrong format. And generally it is not recommended to post the source code. Source code generally needs too much associated information, which is too big to be directly understood. If it is necessary to paste the code, you can write pseudo code and abstract it.

The graduation thesis format includes:
