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

nodeptr current;

HERE is my truble
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??
