"Stray" errors while compiling

[Mankthetank19]

Hello, I am still new with programming in C through Fedora terminal.

I am trying to get an early start on my lab that is on Wed. - so I copy and paste the code and I get Stray errors. I don't know id the "\" is the cause and before I start removing code from the lab, I want to know what is causing this issue. If I comment the lines out, the program while compile so I know it happens to do with those two lines. I "google" the errors and the results seem to be the inputting characters that aren't ASC. Can someone please explain this issue to happen because this is happening on more than one lab for the future. Thanks!

This seems to fix it, am I correct?

from:
memset(&(my_addr.sin_zero), ’\0’, 8);
to
memset(&(my_addr.sin_zero), '\0', 8);
