Consider the following code:
#defined HEADS 0
#incliude "some_library.h"
char * Flip_A_Coin(int x)
{
if (x%2 == HEADS)
return("heads");
else
return("tails");
}
main( )
{
printf("%s\n", Flip_A_Coin(1));
}

Assume that this code is stored in a file named coin2.c andcomplied as follows:
ahoover@video> gcc -o coin2 coin2.c

(a)What sort of error might you expect to see?
(b)On what situation does this error depend??
(c)At what stage of building the program does this erroroccur??
