There is no electronic version of high-number answers, but if you want, high-number answers are sold all year round in the printing shop next to the headquarters basketball court. They printed and bound it, only ten yuan, which is very thick. Secondly, for C language, it is recommended to use Tan Haoqiang's book. Classic works. As for other teaching materials, I suggest you come to the second-hand bookstore in Fudan Handan campus if it is convenient. Personally, I think the second-hand bookstore next to the main entrance is the most comprehensive.

Third, you can go to Fudan Sun Moon Guanghua BBS to find a second-hand book edition or the corresponding professional edition. Maybe a better senior will send it to you directly.

Finally, good luck.
