[hao li <ha...@ya...>]

I have just downloaded 
 
Dev-C++ 4.9.9.0 and try it for funtionality. 
When compiling the basic C source codes it make me trouble
I used create new scource file and
I tried this programs here copied from the helpfile
 
#include <stdin.h>
main()
{
    printf("Hello World\n");
}
 
and
 
 
main() /* main function heading */
{
    printf("\n Hello, World! \n");  /* Display message on */
}                                   /* the screen *
 
 
when compiling it i got the error message
 
in fuction `int main'
printf undecleared
 
does anyone know whats wrong???

First of all, I don't understand why you show two main() functions.

Second, to define printf() you should #include <stdio.h> and _not_
<stdin.h>

Because he said he tried these programs, but he mistakenly written "this =
programs".
You should be more forgiving for language mistakes :)

I didn't care about this/these.

However, I saw two main() but a single #include of a non-existing header
file. I wanted to make sure that is was just an imcomplete cut-and-paste
of two separate programs. When helping someone, it is often useful to
_really_ make sure :)

OMG, this *IS* in the Dev-Cpp's Help file!!!!! o.O
Go to "An introdutcion to C Programming" -> "Topics" -> "Your First 
Program" if you don't believe.
Please someone slap who wrote this chapter. Two times.

Ouch. Besides the misspelled include, the coding style of the example is a
bit ancient.

Not specifying a return type for main, i.e. defaulting to int.

Not specifying any parameter prototypes either, just empty parentheses
wich is something completely different from empty parentheses in C++ where
it would have been a short form for
  main(void)
but in C represents something like
  main(...)
i.e. whatever.
