About VC error c3872: '0 × 3000 ′:

I saw some technologies on the internet today.Code(The code for dynamically generating menus with buttons seems to have been written by one person. Almost no changes have been made.), so the code is copied and tested and executed.ProgramAs a result, I can't think of any trouble. When two simple lines of code are executed, there are actually more than 10 lines of error prompts:

 

Error 1 error c3872: '0x3000 ': this character is not allowed in an identifier

But it seems that the code is correct. That's right! Double-click the prompt to check what went wrong. The result cursor stops on a line of comments, which are some comments copied together. It's useless to think about it. Delete it, run it again, and the result program is successfully executed. Later, it was found that some spaces in some non-normal formats on the webpage were being blamed, which should be the issue of the escape Code. It is incompatible with the characters in Vs, so such strings cannot be identified during vs compilation, an error is reported. Some comments may cause inexplicable problems ..............
