        {

        static int fun(int x)
        {
            int ss, cc;
            ss = x * x; cc = x * x * x;

If a function fun() is to sometimes receive an int and sometimes a double then which of the following is the correct way of defining this function?

Which of the following statements are correct about subroutines used in C#.NET?
1/ If we do not return a value from a subroutine then a value -1 gets returned.
2/ Subroutine definitions cannot be nested.
3/ Subroutine can be called recursively.
4/ To return the control from middle of a subroutine exit subroutine should be used.
5/ Subroutine calls can be nested.

Which of the following statements are correct about the C#.NET program given below?

namespace IndiabixConsoleApplication
{ 
    class SampleProgram
    { 
        static void Main(string[ ] args)
        { 
            int a = 5;
            int s = 0, c = 0; 
            s, c = fun(a); 
            Console.WriteLine(s +" " + c) ;
        }
        static int fun(int x)
        {
            int ss, cc;
            ss = x * x; cc = x * x * x; 
            return ss, cc;
        } 
    } 
} 

1/ An error will be reported in the statement s, c = fun(a); since multiple values returned from a function cannot be collected in this manner.
2/ It will output 25 125.
3/ It will output 25 0.
4/ It will output 0 125.
5/ An error will be reported in the statement return ss, cc; since a function cannot return multiple values.

            Console.WriteLine(i + ", " + j);
        }
        static void funl(ref int x)
        {
            x = x * x;
        }
        static void fun2(out int x)
        {
            x = 6;
