Hi,
This is Lalarukh, I’m seeking community experts help.
Actually I want to show the distance between two entities that is getting as input from User. I’m taking them as simple code. Just want to get the two inputs which are working perfectly and then verify that input value from user is sun & mercury, after verification it should show the distance value as output.
There’s no thing like to sum the distance just want to check the input value & assign the distance between entities.
Here’s the code:
def main() do
IO.puts "Find the distance: "
entity1 = IO.gets "Enter First Entity Name: "
entity2 = IO.gets "Enter Second Entity Name: "
if [entity1, entity2] = {"sun", "mercury"} do
distance = "57909227";
end
IO.puts "Difference between #{String.trim(entity1)} & #{String.trim(entity2)} is: #{String.trim(distance)}km"
end
Sun & Mercury distance is one of example. I want to show the distance of more entities like EARTH & MOON or Sun & Neptune.
def main do
IO.puts("Find the distance: ")
entity1 = IO.gets("Enter First Entity Name: ") |> String.trim("\n")
entity2 = IO.gets("Enter Second Entity Name: ") |> String.trim("\n")
distance = distance(entity1, entity2)
IO.puts("Difference between #{entity1} & #{entity2} is: #{distance}km")
end
defp distance("sun", "mercury"), do: "57909227"
defp distance("mercury", "sun"), do: "57909227"
You can keep on adding to the private distance/2 function to add more support. and then later on generate logic for the sun → mercury, mercury → sun duplications
