Yes pointers,vector, STL are main in cpp . These things make cpp Programming better . If u have not studied pointer vector templates then u have learned nothing. Your third statement cout<<&x<<endl ; &x will print address its not a letters or garbage value. First read concepts about pointers.

Thank you for the answer ! ☺️
