problem in cin

[m1m6]

hello
i have a problem in cin characters
this is my code

typedef char dataline[81];
dataline line;

cout<<">";
cin>>input;

while(input!="XT")
{
	
	if (input=="IN")
	{
		cin.getline(line,SIZE);
		while(line[0]!='/'&&line[1]!='/'&&line[3]!='\0')
		{
			l1.insert(line);
		cin.getline(line,SIZE);
		}
	
	}
	else if(input=="LA")
		l1.list();
	else if(input=="DL")
		l1.Delete();
	else if(input=="MV")
	{	cin>>movment;
		l1.move(movment);
	}
	else if(input=="XT")
		l1.EXIT();
	else
		cout<<"Error Command...!"<<endl;
	cout<<">";
	cin>>input;

}

/* my proplem here 
cin.getline(line,SIZE);
		while(line[0]!='/'&&line[1]!='/'&&line[3]!='\0')
		{
			l1.insert(line);
		cin.getline(line,SIZE);
		}
	
 */

when i trying to input lines
like :
IN
111 1111 1111 111
2222 2222 2222 222
//

should insert into the linked list these lines
111 1111 1111 111
2222 2222 2222 222
just
but it add the // as a line

how i can exclude two slashes??
