Challenge: Understanding Uninitialized Variables

Link to the challenge:

#2

Hi there,
As the comments point out, you should only change code the top area, where you should initialize the declared variables as instructed in the challenge.

Hope that helps!

#3

Thanks a lot Alirezaghey, so what you mean is l make the changes to the first line of code?

#4
  1. Assign values to the variables declared in between those comments. Right now, they are undefined.
  2. Initialize these variables with values that are mentioned on the challenge.
#5

Yes Modiise,

Yes, make the changes to the first three lines of code between the two comments. I write it out here to make sure it’s clear:

// Only change code below this line
var a;
var b;
var c;
// Only change code above this line

Also, keep in mind that this style of challenges is common in FCC where they comment the part of code you are supposed to change.

Hope that helps.
