shared c constants in a header

Question

I want to share certain C string constants across multiple c files. The constants span multiple lines for readability:

const char *QUERY = \"SELECT a,b,c \"
         


        

Answer 1

There are several ways

• place your variables in one file, declare them extern in the header and include that header where needed
• consider using some external tool to append '\' at the end of your macro definition
• overcome your laziness and declare your variables as extern in all your files
