About vectors and all

i am facing difficulties in coding through vectors, i am getting errors when i try to use its various functions, how can i become better in it? suggest me some youtube tutorials?

@sktg99 hey sanchit there is no such hit and trial to learn vectors I don’t think youtube have good content on this topic I would suggest you to take reference from geeks for geeks, techdelight in short you have to do some research on it.
