Only public member functions can access public member data TrueFalse?
False. Public member data is accessible to all functions, whether they be public, protected or private members of the same class, or they are outside of the class completely.
How can you access private functions of a class from the Main function in Cpp?
Any member functions and data members declared as 'private' in a class, can only be accessed directly by functions within the class.They cannot be accessed directly by derived objects, nor from anywhere outside an object of the class, such as from the Main function.To access private class members, you must rely on what are called accessor functions. Accessor functions are functions inside the class, either public or protected, which automatically have access to private members.If a function from Main, or elsewhere outside the class hierarchy, needs access, then you need to use publicaccessor functions. For derived class access, you can use protected accessor functions.
What are different ways by which you can access public member functions of an object?
You simply access it. That's what public means. You can access a public member from any other class, or even from non class code, so long as the referenced class is in scope to the referencing code. In order to do that, you need to have a reference (directly or indirectly) to the instance of the class you want to reference. This would generally be passed as an argument to the referencing code.

What is mean by class access?
Class access is the ability for any given class to access the functions of another class. Private access limits access to data and code just to the class that contains the private access modifier. The so-called "default" access grants private access, as well as access to any class in the same package. Protected access grants the same as "default" access, and also allows subclasses to access the code and data. Public access allows any class in any package to access the code and data.
