Which of the following statements are correct?
1/ An argument passed to a ref parameter need not be initialized first.
2/ Variables passed as out arguments need to be initialized prior to being passed.
3/ Argument that uses params keyword must be the last argument of variable argument list of a method.
4/ Pass by reference eliminates the overhead of copying large data items.
5/ To use a ref parameter only the calling method must explicitly use the ref keyword.

Which of the following statements are correct about functions and subroutines used in C#.NET?
1/ A function cannot be called from a subroutine.
2/ The ref keyword causes arguments to be passed by reference.
3/ While using ref keyword any changes made to the parameter in the method will be reflected in that variable when control passes back to the calling method.
4/ A subroutine cannot be called from a function.
5/ Functions and subroutines can be called recursively.

Which of the following statements are correct?

2/ C# allows a function to have variable number of arguments.
3/ Omitting the return value type in method definition results into an exception.
4/ Redefining a method parameter in the method's body causes an exception.
5/ params is used to specify the syntax for a function with variable number of arguments.
