Question devry cis355a week 1 quiz Latest 2016 may 1. Question : (TCOs 1–8) _____ is interpreted. Pascal Java C++ Ada C Question 2. Question : (TCOs 1–8) What is the printout of the following code? double x = 5.5; int y = (int)x; System.out.println("x is " + x + " and y is " + y); x is 5.5 and y is 5.0 x is 5.5 and y is 5 x is 5 and y is 6 x is 6 and y is 6 x is 6.0 and y is 6.0 Question 3. Question : (TCOs 1–8) What is the value of (double)(5/2)? 2.0 2 3.0 2.5 3 Question 4. Question : (TCOs 1–8) Suppose x=10 and y=10, what is x after evaluating the expression (y >= 10) || (x++ > 10)? 9 11 10 Illegal expression Question 5. Question : (TCOs 1–8) What is y after the following switch statement is executed? x = 3; switch (x + 3) { case 6: y = 0; case 7: y = 1; default: y += 1; } 1 4 2 3 Question 6. Question : (TCOs 1–8) Analyze the following statement. double sum = 0; for (double d = 0; d<10;) { d += 0.1; sum += sum + d; } The program compiles and runs fine. The program runs in an infinite loop because d<10 would always be true. The program has a compile error because the control variable in the for loop cannot be of the double type. The program has a compile error because the adjustment is missing in the for loop. Question 7. Question : (TCOs 1–8) What is the value in count after the following loop is executed? int count = 0; do { System.out.println("Welcome to Java"); } while (count++ < 9); System.out.println(count); 10 9 0 8 11 Question 8. Question : (char)('a' + Math.random() * ('z' - 'a' + 1)) returns a random character _____ between 'b' and 'z'. between 'a' and 'y'. between 'a' and 'z'. between 'b' and 'y'. Question 9. Question : (Tricky) What is the output of the following code? public class Test { public static void main(String[ ] args) { int[ ] x = {120, 200, 016}; for (int i = 0; i < x.length; i++) System.out.print(x[i] + " "); } } 120 200 16 120 200 20 120 200 14 016 is a compile error. It should be written as 16. Question 10. Question : Analyze the following code. public class Test { public static void main(String[ ] args) { int[ ] x = new int[5]; int i; for (i = 0; i < x.length; i++) x[i] = i; System.out.println(x[i]); } } The program displays 4. The program displays 0 1 2 3 4. The program has a runtime error because the last statement in the main method causes ArrayIndexOutOfBoundsException. The program has a compile error because i is not defined in the last statement in the main method.
