[Solved] Please explain the following code in detail [closed]

Question

I can see why you’re having trouble with this pointer variable: it isn’t one. It is a reference.

You cannot have a non-const reference to a const thing. That would violate the const, and allow the n = 11 line to succeed, thus again violating the original const.

const means “I cannot and will not change this thing any more”.

For more information, turn to the page in your C++ book about const.
