If the code in the paper is too long, it is not suitable for direct writing. Look at the mess now, the long code is the best screenshot. If it is short code, you can write it directly. Or don't want to take screenshots, there is another way. 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. Graduation thesis is a thesis that students are required to write before graduation in order to concentrate on the scientific research and training of students in this major. Graduation thesis is usually arranged in the last academic year (semester). The topic of the thesis is designated by the teacher or proposed by the students. After choosing a topic, students conduct research, write and submit papers. The purpose is to cultivate students' scientific research ability, strengthen the training of solving practical problems by comprehensively applying the knowledge, theory and skills they have learned, and generally examine the academic level achieved by students in universities.
