AP Computer Science A, Exam Questions and answers, 100% Accurate, VERIFIED. Consider the following code segment. Sln("W"); Sln("X"); S("Y"); S("Z"); What is printed as a result of executing the code segment? - -D. W X YZ Consider the following code segment. S("cat "); Sln("dog "); Sln("horse "); S("cow "); What is printed as a result of executing the code segment? - -B. cat dog horse cow Consider the following code segment. S("Hello!"); Sln("How "); S("are "); S("you?"); What is printed as a result of executing the code segment? - -D. Hello!How are you? Consider the following code segment. Sln(hello); // Line 1 S(world); // Line 2 The code segment is intended to produce the following output but does not work as intended. hello world Which of the following changes can be made so that the code segment produces the intended output? - -D. Changing print in line 2 to println Consider the following code segment. S("Ready"); // Line 1 S("Set"); // Line 2 S("Go!"); // Line 3 The code segment is intended to produce the following output but may not work as intended. Ready Set Go! Which change, if any, can be made so that the code segment produces the intended output? - -A. Changing print to println in lines 1 and 2 Each of the following code segments is intended to print the word Hello. Which of the following code segments works as intended? I. S("Hello"); II. S(Hello); III. S(He); S(llo); - -A. I only Which statement correctly declares a variable that can store a temperature rounded to the nearest tenth of a degree? - -B. double patientTemp; A teacher determines student percentages in a course as the points a student earns divided by the total points available in the grading period. Points are awarded only in whole number increments, but student percentages are to be stored as decimals. The following code segment appears in a program used to compute student percentages. Points that a student earns are stored in pointsEarned, the total points available in the grading period are stored in totalPoints, and the student percentage is stored in percentage. int pointsEarned; /* missing code */ Which of the following is most appropriate to replace /* missing code */ in the program? - -C. int totalPoints; double percentage; Consider the following code segment: /* data type 1 */ x = 0.5; /* data type 2 */ y = true; Which of the following best describes the data types that should be used to replace/* data type 1 */ and /* data type 2 */ so that the code segment compiles without error? - -D. The variable x should be declared as a double and the variable y should be declared as a boolean. Consider the following code segment. int x; int y; x = 3; y = /* missing expression */; x = 1 + 2 * y; S(x); Sln(y); Which of the following can be used as a replacement for /* missing expression */ so that the code segment prints 94 ? - -D. x + 1 The volume of a cylinder is equal to the height times the area of the circular base. The area of the circular base is equal to π (pi) times the square of the radius. The code segment below is intended to compute and print the volume of a cylinder with radius r and height h. Assume that the double variables r, h, and pi have been properly declared and initialized. /* missing code */ S(volume); Which of the following can be used to replace /* missing code */ so that the code segment works as intended? I. double baseArea = pi * r * r;double volume = baseArea * h; II. double volume = pi * r * r;volume = volume * h; III. double volume = pi * r * r * h; - -E. I, II, and III Consider the following code segment. int x = 10; int y = 20; /* missing code */ S(top / bottom); Which of the following replacements for /* missing code */ will cause an ArithmeticException to occur? I. int top = x - y;int bottom = y - x; II. int top = 2 * x;int bottom = y - top; III. int top = x + y;int bottom = 2 * top; - -B. II only Consider the following code segment. int a = 1; int b = 2; int c = 3; int d = 4; double x = a + b * c % d; What is the value of x when the code segment has been executed? - -C. 3.0 Which of the following arithmetic expressions evaluates to 1 ? I. 2 / 5 % 3 II. 2 / (5 % 3) III. 2 / 5 + 1 - -D. II and III onl
