Why the main function is public and static?
The main function is public because it means it needs to be called by any object. I had to check this myself but if you try to make the main function in Java private it will give you a run time error. It is static because it is indicating it is a class method and it does not need to be instantiated. Without the static keyword you would need to do something like this Main main = new Main();
How do you access global variable from within the main function when the local variable is of the same name?
When you acess a global variable inside main function you must use the same name, because the variable declared as global can be accessed by any function/procedure on the class where it was defined.

Why main function written as public static in java?
They are public because they must be accessible to the JVM to begin execution of the program. Main is the first method that would get executed in any class.They are static because they must be available for execution without an object instance. you may know that you need an object instance to invoke any method. So you cannot begin execution of a class without its object if the main method was not static.OrMain is starting point of the program execution Main method is called by JVM there is no need for JVM tocreate an object of the class just to access Main function
In java how the class containing main is executed with out creating an object?
You may know that static methods in Java are executed even before the constructor of that class are called. Similarly, since the main method is static it gets executed first even before the others methods of the class are called. Since it is being called before the constructor, logically speaking you cannot have objects of that class.
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.
