C++ Jump/Loop to the last line of a text file

Question

I'd like to jump/loop through to the last line of a text file, read only the first character from that line and store it within an int called "id". Can somebody please explain how I would achieve this? The content of the text file is as follows:

1 Chris Boy 5
2 Stephanie Girl 8
3 Zack Boy 1

I managed to work this out using the link tacp provided. My code is as follows:

if (inStream.is_open())
    {
        inStream.seekg(-1, ios_base::end);

        getline(inStream, lastLine);

        id = stoi(lastLine);

        id = id + 1;
    }
    else
    {
        cout << "Unable to open staffMembers.txt.\n";
        exit(1);
    }
