Consider the following program segment in which the statements are jumbled, choose the correct order of statements to swap two variables using the third variable.

void swap(int a, int b)
{	
  a = b;      → (1)
  b = t;      → (2)
  int t = 0;  → (3)
  t = a;      → (4)
}

1. (1) (2) (3) (4)
2. (3) (4) (1) (2)
3. (1) (3) (4) (2)
4. (2) (1) (4) (3)

Assertion (A): An argument is a value that is passed to a method when it is called.

Reason (R): Variables which are declared in a method prototype to receive values are called actual parameters

1. Both Assertion (A) and Reason (R) are true and Reason (R) is a correct explanation of Assertion (A)
2. Both Assertion (A) and Reason (R) are true and Reason (R) is not a correct explanation of Assertion(A)
3. Assertion (A) is true and Reason (R) is false
4. Assertion (A) is false and Reason (R) is true

Evaluate the given expression when the value of a=2 and b=3

b*=a++ - ++b + ++a;
System.out.println("a= "+a); 
System.out.println("b= "+b);

A student executes the following program segment and gets an error. Identify the statement which has an error, correct the same to get the output as WIN.

boolean x = true; 
switch(x)
{ 
  case 1: System.out.println("WIN"); break;
  case 2: System.out.println("LOOSE");
}
