C# C# Objects Encapsulation and Arrays Arrays

C# Objects Array Challenge Help.

I don't know if it's just me not understanding the question, or if I am just reading it wrong. Originally I thought I was suppose to set the value of the third item in the array, like a key-value pair. Then I read it again and it seems like I am suppose to set lap3 as type double and add the third item in that way. I keep getting an error that asks me if I indexed into the third item of the 'finalLapTimes' array and I did. So I am at a lost for words on what I am doing wrong.

CodeChallenge.cs 
double[] lapTimes = new double[4];
lapTimes[0] = 2.2;


double[] finalLapTimes = new double[4] {2.2, 2.3, 2.5, 2.8};
double lap3 = 2.5;
finalLapTimes[2] = lap3;

Your code should look like this:

double[] lapTimes = new double[4]; lapTimes[0] = 2.2;

double[] finalLapTimes = new double[4] {2.2, 2.3, 2.5, 2.8}; double lap3 = finalLapTimes[2];

Yes this does actually work. Thank you! It looks like I was really close to the answer.

Thank you for responding to me, but that doesn't work. lap3 has to be the third item in the array finalLapTimes. Setting finalLapTimes array call to 1 would be the second item in the array.

Sorry about that, I amended my answer :)

double[] lapTimes = new double[4]; lapTimes[0] = 2.2;

double[] finalLapTimes = new double[4] {2.2, 2.3, 2.5, 2.8}; double lap3 = finalLapTimes[2];

The assignment is "Declare and initialize another array of doubles named finalLapTimes with the following times: 2.2, 2.3, 2.5, 2.8." and there's no mention of "double lap3 = finalLapTimes[2];". Could you tell me how "double lap3 = finalLapTimes[2];" was relevant since the question/assignment mentioned nothing about that?

As it turns out that's relevant to question 4/4 but I couldn't get past 3/4 without it. How did you know?
