Not Able to Understand

I am not able to understand this video - ‘cin.get() for input’.
How can I understand it in a better way??

Hello @gaurisha whenever you use cin before getline(cin,s) you have to use cin.get()
this is because Assuming you have pressed enter after taking input n using cin , the newline character was also put on the stream. When you call cin.get() after that, it will grab and discard the newline character, allowing the rest of your code to properly get the input.
please check this.
