Create a linked list from space separated input

Question

I am trying to make a linked list from space separated integer input.

Input:

1. Number of nodes
2. Space separated input

int main()
{
    int n;
    cout<<"Enter number of nodes";
    cin>>n;
    cout<<"\nEnter data"<<endl;
    int temp;
    lNode *head = NULL;
    while(cin>>temp)
    {
        CreateLinkedList(&head,temp);
    }
    PrintLinkedList(head);

    return 0;
}

Here I am not getting how to limit the user input to the number of nodes which he has given as first input. Is there any other way to get user input?

Answer 1

You can ask the input as a string:

string line;
getline(cin, line);

Then you can separate the entered numbers in the line using stringstream so you should include the sstream library (eg. #include <sstream> ):

stringstream ss(line);
int number;

while(ss >> number) {
    ... do whatever you want to do with the number here ...
}
