My object variable is producing a Error

regnar86 (18)
I'm trying to set up a class for a resistor program. The program is not complete yet but I'm trying to figure out why I have a error on the line that has my object variable "resistor myresistor".

ERROR:

SEMANTIC ISSUE.....
Call to constructor of "resistor" is ambiguous

Also is there a better way I could set up my class to where it's not so extensive. I will eventually be implementing 5 and 6 band resistors. The program will also need to take a a value and print out the colors as well. I'm having a hard time figuring out the process of determining what member variables I will need. Functions shouldn't be too hard to figure out as they are the functions that will be doing the calculations and printing out values.

Because all of them have default values for all their parameters the compiler doesn't know what constructor to use.
