    Unhappy for loop problem

    Hello I have a question. Why is it that this 2 for statements combines each time I execute it.
    Instead of writing 10 "." each, it writes 20 "." instead. Can you guys help me?

    I want to execute the program like this:
    Enter IP Address:
    Enter Port Number:

    ..........<--delay()
    Connected to remote host "<<ip<<" at "<<"port "<<port
    Exiting
    ..........<--delay()

    I need the experts help please. Thank you very much!

    Code:
    void timer();
    void connect();
    
    char ip[15];
    int port;
    main ()
    {
    cout<<"Enter IP Address: ";
    cin>>ip;	
    cout<<"Enter Port Number: ";
    cin>>port;
    connect();
    timer();
    
    return 0;
    }
    void connect()	
    {	
    	cout<<"\nConnected to remote host "<<ip<<" at "<<"port "<<port;
            cout<<"\nExiting";
            for (int a=0;a<10;a++)
            { 
                      printf(".");
                      Sleep(500);
            }	
    }
    void timer()
    {
        int i;
    	for( i=0;i<10;i++)
    	{
    		printf(".");
    		Sleep(500);
    	}
    }

    because the for loop in connect() is after you print the "connected to host" message?

"Finding the smallest program that demonstrates the error" is a powerful debugging tool.
