Question

Consider the following code segment: results_1 = mod (testVal, 4) = 0; results_2 = mod (testVal, 100) = 0; results_3 = mod (testVal, 400) = 0; results_4 = (result_1 66 result_2) 11 (result_3); If testVal holds the value 500, identify the result (i.e, result_3) of the test found on line three (3) in the given code. Circle the letter to the left of the selection to indicate your answer. a. 400 b. 500 c. true d. false e. All of these selections are correct f. None of these selections are correct Again, it testVal holds the value 500, identify the result (i.e, result_4) of the test found on line four(4) in the given code. Circle the letter to the left of the selection to indicate your answer. a. 4 b. 100 c. 400 d. true e. All of these selections are correct f. None of these selections are correct Consider the following code segment. for index = 1: array Size % ??? % fprintf(', '); % end fprintf('%d', array (index)); end If it is desired to have a comma after all of the displayed values except the last one, select the correct statement for line 3 from the following choices. Circle the letters to the left of the selection to indicate your answer. a. if index 1 d. if index

Explanation / Answer

1. testVal = 500, means result_3 = mod(500, 400) == 0, which is false, because 500 is not divisible by 400. Option D

2. testVal = 500, then
   result_1 = true, because 500 is divisible by 4
   result_2 = true, because 500 is divisible by 100
   result_3 = false, because 500 is not divisible by 400

result_4 = (result_1 && ~result_2) || ressult_3 = (true && false) || false = false || false = false; (Option f)

3. Option C,
We need not print the comma only for the first number, i.e. when index =1, after that before each number, we need to print the comma.. Hence Option C => if(index > 1)
