Error display:

This is what I saw on the Internet. It took more than half an hour to figure out the source image, but there are still a lot of problems. The online stuff is really untrustworthy. It seems that most of them are in C language, if you have time, please help me change it to C ++, find out the error and correct it. Thank you. If you are a newbie, please take care of it...
