From error it looks tike you don't have main function anywhere
odai (57)
no i have it !! what about my code is there any mistake in it ?

and how can i call it in main ?
MiiNiPaa (8886)
array_of_queue1 = new a[b]; Makes no sense.

first=c=0;
last=d=0;
Useless. Why you even bother with sending variables if you will make it =0 anyway?

and how can i call it in main
It is a member function. Constructor to be precise. Why do you wrote it that way if you don't know how to use it?

I want to say it again: Error you got tells that there isn't main() function anywhere. There is several possible reasons:
* cpp file where main() is is not included in project build list.
* Showing great deal of standard compliance (sarcasm mode off) MSVC is waiting for function named differently from main() ( possibly _tmain(), check your compiler settings )

ok i know what do you mean mmm

now my code is like 

1

3
4
5
 
private:
	T1*array_of_queue1[10];
	int size;
	int first;
	int last;


queue1();//constructor

template<class T1>
queue1<T1>::queue1()

{
	size=10;
	first=0;
	last=0;
}





in main 

1
2
 
queue1<int> v;
	v.ADD(2);



but the compiler still give the same error !!
so is it like what do you say " Showing great deal of standard compliance (sarcasm mode off) MSVC is waiting for function named differently from main() ( possibly _tmain(), check your compiler settings )" ?

There is no #endif at the end of your header.
queue_1& queue_1<T1>::operator(queue_1&)
operator what?

And I still think that cpp file where your main function is is not in compile list. Because if this was compiled it were compile-time errors, not linking ones.
odai (57)
there is #endif in line 24!

mmm really i dont know what is wrong !
MiiNiPaa (8886)
That means you could include several template definitions...

Create new project. Copy all your old code in it. Try to compile.
odai (57)
yes i will do that plz wait me ^_^
odai (57)
my program working but there's wrong in this function !!
