Hi,

I am new to djgpp and C, so be kind. I am working through a book on C
and the program

#include <stdio.h>
#include <conio.h>
void clrscr(void);
int days[]={31,28,31,30,31,30,31,31,30,31};
main()
{
 int index;
 extern int days[];

 clrscr();

 for(index=0;index < sizeof days/(sizeof(int));index++)
    printf("Month %d has %d days.\n",index+1,days[index]);
 return 0;
}

bombs with error message "sizeof applied to incomplete type." I tried
Ctrl+F1, but no help provided. Apparently, the sizeof command is not
part of libc? Am I correct in this? How does one use one's djgpp and
RHIDE setup to get help on standard commands such as sizeof, for, while,
etc?

Can anyone suggest what I am doing wrong? Best workarounds?

Email appreciated.
