Question:
Which of the following statements is correct about the C#.NET code snippet given below?int i, j, id = 0; switch (id)
{ 
    case i:
        Console.WriteLine("I am in Case i");
        break; 
    
    case j:
        Console.WriteLine("I am in Case j");
        break;
}

1.The compiler will report case i and case j as errors since variables cannot be used in cases.

2.Compiler will report an error since there is no default case in the switch case statement.

3. The code snippet prints the result as "I am in Case i"".

4.The code snippet prints the result as "I am in Case j".

  2. Which of the following statements are correct?A switch statement can act on numerical as well as Boolean types. A switch statement can act on characters, strings and enumerations types. We cannot declare variables within a case statement if it is not enclosed by { }. The foreach statement is used to iterate through the collection to get the desired information and should be used to change the contents of the collection to avoid unpredictable side effects. All of the expressions of the for statement are not optional.

Which of the following statements are correct about the C#.NET code snippet given below?if (age > 18 && no < 11) a = 25; The condition no < 11 will be evaluated only if age > 18 evaluates to True. The statement a = 25 will get executed if any one condition is True. The condition no < 11 will be evaluated only if age > 18 evaluates to False.

  14. Which of the following statements are correct?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. The goto statement passes control to the next iteration of the enclosing iteration statement in which it appears. Branching is performed using jump statements which cause an immediate transfer of the program control. A common use of continue is to transfer control to a specific switch-case label or the default label in a switch statement. The do statement executes a statement or a block of statements enclosed in {} repeatedly until a specified expression evaluates to false.
