Do not repost questions, you have already posted the same question here, [Class shape and related functions](https://www.codeproject.com/Questions/1197886/Class-shape-and-related-functions). If someone is active to answer your question, they will do it. If there is no one, reposting the question doesn't help at all.

What error? The compiler ones? - Then show us the errors. Or you meant the incorrect output? - Then try to debug your code.

There does not seem to be a Rectangle::printFourVertices() method. There is a redundant assignment operator in the Point::setX() method. Short of that, what's the issue? "I am getting errors" is meaningless.

I corrected the entire code , but the only thing now I dont know is how to implement this Print four Vertices function . I want to know how to implement anf declare this function . Beside that , I corrected the rest of code

How would you do it using pencil and paper? If you coded up everything that calculates said vertices, printing them should be a non-issue, yes?
