stupid error

[tomtetlaw]

idk why i get this error i just do

here is the code i have:

#include "includes.h"

int main()
{

}

here is the error:
c:\documents and settings\tom\my documents\visual studio 2008\projects\c++ tutorial\c++ tutorial\main.cpp(3) : error C2143: syntax error : missing ';' before 'int'

any ideas?

[rahul8590]

At the first place i dont know wat r u trying to do here .

Well i guess if you include the main header file also i.e
#include<iostream.h>
u may not get this error.

[tomtetlaw]

thats included in std_lib_facilities.h, its for a tutorial im doing. mabey the VC++ compiler is just screwing up

[rahul8590]

yeah .. that sounds k . but did you try this way i mentioned . before ?

[tomtetlaw]

still does the same thins :S

[jbennet]

main needs paramaters and needs to return a value, else its not valid standard c++

[tomtetlaw]

i tried that and it still doesnt work :(

[rahul8590]

well when i ran this program

#include<iostream.h>
int main()
{
}

it didnt give me ne errors .
well i work on codeblocks IDE and GCC compiler i guess

[mitrmkar]

Maybe you could post the "includes.h" file?

as i said before, this code is all for a book i bought called "Programming principals and prictice using c++" by Bjarne Stroustrup(the original designer and implementer of c++)
this code has worked before(as far as i can remember)

all your help has and will be apprecieted :)

[Nick Evan]

Your missing a semicolon ( ; ) at the end of your class in maindef.h. So add one after the last } ( so: }; )

[MrSpigot]

A semi-colon wouldn't go amiss at the end of this definition in maindef.h :

template<typename t> class list {...};

[tomtetlaw]

thanks man that fixed it. :D
