318 Pointscoding a for in loop
For this challenge, we're going to use a for in loop to compute the multiplication table for 6 and append the results to an array.
To start off, I've created an empty array of type Int and assigned it to a variable named results. Note that we have to explicitly declare the type here so that the compiler knows this array will hold Int values.
Your task for this step is to create a for in loop that iterates over a range. Multiplication tables typically range from 1 to 10 (with 10 included) so the range you are iterating over should go from 1 to 10.
For in loops also define a constant that temporarily stores the value in the iteration process. For the loop you're writing, name this constant multiplier.
I have watched the videos 3 times and I am still clueless at how to do this
