You need a loop of some kind to go back and open the next site.
Something like this:

1
2
3
4
5
6
7
8
9
10
11
12

#include <iostream>

int main()
{
    // ...
    int site ;
    do
    {
        std::cout << "enter one of the numbers (or -1 top quit): " ;
        while( !( std::cin >> site ) )
        {
            std::cout << "please enter a number: " ;
            std::cin.clear() ;
            std::cin.ignore(1000,'\n') ;
        }
        switch( site )
        {
            case 1 :
                /* open site 1 */
                break ;

            case 2 :
                /* open site 2 */
                break ;
            // etc ..
        }
    } while( site != -1 ) ;
}

Can you put it on the code please ?

I suppose I can; but then you wouldn't be learning anything, would you?

Make an attempt to do it on your own; if you encounter difficulties, post a question and someone here would help you out.

The first time i wanna open a web-site nothing happens , it only happen at the second time ..

Difficult to say why that should happen, without having a look at the code.

Yes thanks , it helped me , but i have a question , is there any way to change the quit command ( -1 ) to something else like "quit" or "exit" ?

You can add an additional option "exit" to the program menu and then use system("exit").

                case 8 :
                     system("exit");
                     break;
                default :
                     cout<<"\n|--|The number you entred is wrong !|--|\n\n";
                     break ;
        }                 
   } while( site != -1 ) ;
}


IDK if you meant this , this is what i done and when i press 8 nothing happen , it just ask like normal to put another number in it ( NOT WRONG NUMBER ERROR )
TheGrayWolf (96)
It's because you are still in the loop. You could have an exit flag, say 

1
2
 
 
int exit = 8;


and then instead of 

1
2
 
 
while( site != -1 )


you use 

1
2
 
 
while( site != exit )


JLBorges (13770)

There is; you need to accept the input as a sequence of chars - a std::string - not as an integer. And then examine what that input string contains.
