Vectors And Constructors - Shed Me Some Light On It

Hey guys, hows it going? I am going through some exercises about constructors and vectors and I came across a difficulty which I am hoping someone in here could help to clarify.

The exercise says: “A void must initialize the vector with 10 positions and another that receives as a parameter the vector’s desired amount of positions. Apply the reuse of constructors through the word “this”.”

Thank you all :slight_smile:

Is there anyone around who would know how to explain?
