C++ cin question

Question

In this code:
https://code.sololearn.com/936/#cpp
I have two cins but it only put out one "Seems like you program requires an input". Why is this?
Thank you for helping.

Answer 1

because of running code on solo learn app is not on your machine, its on their server so please; separate your input with new line

Answer 2

that message comes up regardless of how many inputs you have (it says to separate multiple into different lines)
