B. 
int a = 1, b = 2, c = 0;
a < b ? c = a : c = 0;
C. 
int a = 1, b = 2, c = 0;
a < b ? c = a : c = 0 ? 0 : 0;
D. 
int a = 1, b = 2, c = 0;
a < b ? return (c): return (0);

17. Which of the following statements are correct?

  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.
A. 1, 2, 4
B. 1, 3, 5
C. 2, 3, 4

18. Which of the following statements are correct about the C#.NET code snippet given below?

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.
A. 1, 4, 5
B. 2, 4
C. 1, 3, 4
D. 2, 3, 5
E. None of these
