Fairly certain you can have compound statements as the result of the macro. e.g., the macro could expand to if(a) {printf("%d\n", b);} for example

You can. Of course you don't even need the logical connector

    #define f(a,b)  \
        f_var1 = a; \
        f_var2 = b

Equally you could use macros to make it a whole lot worse

    #define f(a,b)  \
        f_arr[a][b] += f_arr[b][a]
