1. The copy constructor is used to initialize the members of a newly created object by copying the members of an already existing object. 2. Copy constructor takes a reference to an object of the same class as an argument. If you pass the object by value in the copy constructor, it would result in a recursive call to the copy constructor itself.

Left Shift (<<) It is a binary operator that takes two numbers, left shifts the bits of the first operand, and the second operand decides the number of places to shift. In other words, left-shifting an integer “ a ” with an integer “ b ” denoted as ‘ (a<<b)’ is equivalent to multiplying a with 2^b (2 raised to power b). Syntax: a << b;Navigate to the directory that contains the new executable, using the command prompt or File Explorer. 2.
