missing terminating ' character (C, version 13, Xcode Terminal)-CodePudding

I'm just getting into C and this is the code I'm trying to get the compiler to run using gcc:

#include <stdio.h>

main()

{

printf("hello, world\n");

}

Every time I type gcc helloworld.c (helloworld.c is the name of the source file), the following error message appears:

helloworld.c:1:1: error: expected identifier or '('
{\rtf1\ansi\ansicpg1252\cocoartf2580
^
helloworld.c:13:9: warning: missing terminating ' character [-Winvalid-pp-token]
printf(\'93hello, \'93);\
        ^
1 warning and 1 error generated.

I tried switching to single quotation and putting quotation marks around every single character but nothing worked. Does anyone have any ideas what's wrong with the syntax?

Try writing the program out by hand. If you copy-pasted it from somewhere, you might have put some weird invisible characters and formatting stuff. I copy-pasted the code from your example and it worked just fine. Compiled successfully with GCC:

gcc input.c -o program
