Gauss' law is a very useful tool for dealing with electric and gravitational field forces. It says the the amount of electric field coming out of any enclosed area is equal to the amount of charge inside that area. If you have a sketch of an electric field, and you draw a loop somewhere in that field, and you count up all the field lines going out of that loop and subtract the number going in, you should get the total amount of charge inside the loop.

It's important to remember that the field line itself is not where all the force of the field is located. Rather, field lines are marked off in such a way that there is s set amount of field going through the space between the lines. In the examples you have done on the computer, the field lines are drawn so that there is 1 C worth of field between them. So, if I draw a line between two field lines, the amount of field going through that line is equal to the amount of field that would go through a loop around a 1 C charge.
