Question
This is my code but I keep getting this warning:1>c:usersdocuments esistor[1] esistor esistormain.cpp(116): warning C4244: 'argument' : conversion from 'double' to 'int', possible loss of data.
This is the code. Can someone run this and fix the problem as I can't figure it out?

Explanation / Answer
The function Validate takes the first argument as 'int', while you are passing 'normalResistance' is double type. Either typecast it before passing as (int)normalResistance, or change the function defination to Validate(double value, int allowedValues[], int size). This will solve the warning problem.
