store data from ifstream and store in link list

hi everyone, i have no idea on how to store values into a link list which data is from IFSTREAM

for example..the data.txt as below
192.149.089.061
100.001.004.031
034.056.078.012
192.149.089.061
100.001.004.031
192.149.089.061
111.022.033.004
192.149.089.061
111.022.033.004
111.022.033.004

and i want to stored it in link list .. how can i make it ???

this is my main code

Code:

int main()
{
    IPlist ip;  
	ifstream myFile;           //input file stream variable
    char filename[40];         //filename is used to store the name of the input file
    
     
    cout<<"Enter name of file : ";
    cin>>filename;
    myFile.open(filename); //open the input file 
    
    while(!myFile) //if open did not fail
    {
        myFile.clear();
        cout << "Invalid file name" << endl;
        cout << "Enter name of file : " ; //read the name of the input file
        cin >> filename;
        myFile.open(filename); //open the input file 
    }
    while(myFile>> filename)
    {
        cout << filename << endl;
    }
    
    if (ip.empty())
    
    
    
    system("pause");
    return 0;
}

any help and idea will be really appreciated ... thank you

Replace cout << filename << endl with code that adds the data to the list.

yap i got tat.. erm,, can you check this error for me please..i have two version....

Code:

void IPlist::updateCount(string address)
// precondition : address is in list
// postcondition : the count of node with address has been incremented
{
    node *tmp = list;
    tmp->count = 0;
    while(tmp != NULL && isPresent(address) )
    {
        tmp->count++;
        tmp = tmp->link;
    }
}

Code:

void IPlist::updateCount(string address)
// precondition : address is in list
// postcondition : the count of node with address has been incremented
{
    node *newList = new node;
    newList->IPaddress = address;
    newList->count = 0;
    //newList->link = NULL;
    
    if( isPresent(address) )
    {
        newList->count++;
        newList = newList->link;
    }
}
