OK i read some matirial about the list

but let's get to the point...

If for example my class name is Gas_station and i want to creat a list of Gas_station Object's at size of (argc-2) what do I write down ?
is it

list<Gas_station> lst(argc-2,Gas_station() );

I alreadt know how to creat an object but not for a list...
I mean 
1
2
 
Gas_station Gas1;
Gas1.**** //some method


but how dose it works in the list ?

You use an iterator to traverse the list. If you dereference the iterator then you have the object and can use the methods you want.
1
2
3
4
 
list<Gas_station> l;
//...
list<Gas_station>::iterator it = l.begin();
it->some_method(); // equivalent to (*it).some_method();

I write like this ...

1
2
3
4
5
6
7
8
9
10
 
	list<Gas_station> lst( 0,Gas_station() ); // Creates list 
	for( int counter=0 ; counter<3 ; counter++ )
	{
		Gas_station::Gas_station();//default constructor
		Gas_station Station1;//creat an object
		lst.push_front(Station1);//pushing it to the front of the list

                                // inserting the data to members

                 }


Is it right ?

you can write it as
1
2
3
4
5
6
7
8
9
 
    list<Gas_station> lst; // Creates list 
    for( int counter=0 ; counter<3 ; counter++ )
    {
        Gas_station Station1;//creat an object
        lst.push_front(Station1);//pushing it to the front of the list

                                // inserting the data to members

     }
no secrets there

EDIT: Note that 'push_front' takes a copy hence you have to set Station1 properly before you 'push_front'. Or you manipulate lst.front() afterwards.

The code that you give as an example ... is it saving the Station1 members?

and if yes how do i get to their values?

and how I can chack if it works ?

yep

and if yes how do i get to their values?
list<Gas_station>::iterator (for example) or front() or back()

and how I can chack if it works ?
however, you can iterate and print the member or alike
