What's wrong with this C program? (Global variables)

I am new to C and im trying to work with Global variables i ran this program and all get as output is "Hey there" Which is the first part of the program. The second part doesn't get displayed. Here's the code. 

char count[20]="Hey there";
char dig[7]="pooop"; 

main()
{
    puts(count);

    return(0);
}
hey()
{
       printf(" i %s you", dig);

    return(0);
}

You need to call the second function hey() before you can get its output.

E.g., in main()

{
   puts(count);
   hey();
   return 0;
}

where exactly you put the call to hey() in main() is up to you (it needs to be before the return statement though).

The function hey isn't called. I can't really explain this further without writing a programming textbook here. So you'll need to find one.

You need to invoke the function hey() someplace if you want it to run. C programs start with main(), and whatever main does is what the program does. Call hey from main if you want hey to run.
