Calling copy constructor

pls show by example what sir meant when at last of the video sir mentioned that we can call the copy assignment operator as many times as possible and not possible for the constructor operator.

Please mention the video and the time stamp in the video so that i can check.
In a program, constructor is invoked only once…ie. when an object of that class is created. But copy assignment operator can be invoked many times. It is used to copy one object’s value to another
