If a function fun() is to receive an int, a Single & a double and it is to return a decimal then which of the following is the correct way of defining this function?

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

1. The switch statement is a control statement that handles multiple selections and enumerations by passing control to one of the case statements within its body.
2. The goto statement passes control to the next iteration of the enclosing iteration statement in which it appears.
3. Branching is performed using jump statements which cause an immediate transfer of the program control.
4. A common use of continue is to transfer control to a specific switch-case label or the default label in a switch statement.
5. The do statement executes a statement or a block of statements enclosed in {} repeatedly until a specified expression evaluates to false.

int i = 1, j = 1, val;
while (i < 25)
{
    Console.Write(j + " ");
    val = i + j;
    j = i;
    i = val;
}

if (age > 18 || no < 11)
    a = 25;

1. The condition no < 11 will get evaluated only if age > 18 evaluates to False.
2. The condition no < 11 will get evaluated if age > 18 evaluates to True.
3. The statement a = 25 will get evaluated if any one one of the two conditions is True.
4. || is known as a short circuiting logical operator.
5. The statement a = 25 will get evaluated only if both the conditions are True.

int i = 0, j = 0; 

label:
    i++;
    j+=i;
if (i < 10)
{
    Console.Write(i +" ");
    goto label; 
}

namespace CuriousTabConsoleApplication
{ 
    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.

        {
            for (int i = 0; i < obj.Length-1; i++)
            Console.Write(obj[i] + " ");
        }
