(c language) 02 - multiplication and addition of linear structure 2-ary polynomials (20 points) (detailed explanation)

It's also a question about the structure of linear table. When we get the question, although we see the amount of question is very short, in fact, the amount of code it implements is quite large. Therefore, understanding the topic can write a long code. #include<stdio.h> #include<stdlib.h> t ...
