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

      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.

    • Options
    • A. 1, 3
