Question

1.Which of the following is the correct code snippet for throwing a pair of 12-sided dice to get a sum of the numbers on two dice between 2 and 24 with different probabilities

		2 * (rand() % 11 + 2)
		rand() % 23 + 2
		(rand() % 12) + (rand() % 12)
		(rand() % 12 + 1) + (rand() % 12 + 1)

2.What would be the correct replacement for the following if () statement ?

if (0 > temperature > 212)

		It is correct, no need to replace the statement.
		if (0 > temperature && temperature > 212)
		if (0 > temperature || temperature > 212)
		if (0 > temperature and temperature > 212)

3.What, if anything, is syntactically wrong with the following function definition?

int sign(int x) 

{ 

   if (x < 0) 

      return -1;  

   else if (x > 0) 

      return 1;  

}

		It should have a double argument, not an int.
		If x == 0, neither return statement is executed.
		The if() statement needs braces {}.
		The code has no syntax errors.

4.What is calculated by the code snippet?

int n = 0;

int x;

while (cin >> x)

{

   if (x > n)

   {

      n = x;

   }

}

		The average of the input values
		The number of input values
		The minimum value of all input values
		The maximum value of all input values

Answer 1

1)  D.  (rand() % 12 + 1) + (rand() % 12 + 1)
2)  B.  if (0 > temperature && temperature > 212)
3)  If x == 0, neither return statement is executed.
4)  D.  The maximum value of all input values
