c Language blanking function question!

https://jink1982.tistory.com/159 See strcpy() function for now...It's the process of checking if the statement is blank and calling the strcpy() function to copy the next character to the current location (blank)...But looking at the code above, I think we need to process the rest of the strings.

Oh, now that I see it again, it's a copy of the string itself...I don't think it's a problem
