1. Draw a flowchart for the following:

a. Draw a flowchart or write pseudo code to represent the logic of a program that allows the user to enter a value. The program divides the value by 2 and outputs the result.

Start

Input myNumber

b. Draw a flowchart or write pseudo code to represent the logic of a program that allows the user to enter a value for one edge of a cube. The program calculates the surface area of one side of the cube, the surface area of the cube, and its volume. The program outputs all the results.

start

input cubeSide A

set cubeSide A area = cubeSide A * cubeSide A

set totalSurFaceArea = 6 * cubeSide A area

set cubeVolume = cubeSide A * cubeSide A * cubeSide A

output cubeSide A area

output cubeVolume

output totalSurFaceArea

stop

c. Draw a flowchart or write pseudo code to represent the logic of a program that allows the user to enter two values. The program outputs the product of two values.

Start

Input number3

Input number7

Set answer = number3 * number7

Stop

d. Draw a typical hierarchy chart for a program that pseudo code a monthly bill for a cell phone customer. Try to think of at least 10 separate modules that might be included. For example, one module might calculate the charge for daytime phone minutes used.

e. Draw a structured flowchart or write structured pseudo code describing how to do a load of laundry. Include at least two decisions and two loops.

Start

open washing machine door

while dirty clothes in the hamper is true

put dirty clothes in washing machine

endwhile

pour in detergent

if this is a cold load then

set temperature to cold

else

set temperature to warm/hot

endif if

fabric softener is needed then

pour in fabric softener

endif

close washing machine door

start washing machine

while the washing machine is running is true

endwhile

stop

f. Design a flowchart or pseudo code for a program that accepts two numbers from a user and displays one of the following messages: First is larger, Second is larger, Numbers are equal.

Start

Input first,second

If first is greater than second then

Output ”first is larger”

else

Output “second is larger”

If first=second then

Output “numbers are equal”

End if

Stop

a. What output is produced by the following code fragment? Explain.

i. System. out. print(“Java ”)

System. out. print(“Programming”);

ii. System. out. println(“Java ”)

System. out. println(“Programming”);

b. Write a single Java program statement to display the text below and explain why it is written like that.

“A piano has

88 keys”

c. What output is produced by the following code fragments?

i. System. out. println (“Result : “+ 40+30);

ii. System. out. println (“Result : “+ (40+30));

d. What output is produced by the following code fragments?

i. System. out. println(“A \ “lable\ “ can contain either \n\ttext,

\n\tan image, or \n\tboth. ”);

e. What value is contained in the integer variable value after the following statements are executed?

value=16;

value=value+5;

value=value+1;

value=value/3;

f. What result is contained in the integer variable value after the following statements are executed?

value=10;

value +=10;

value *= value;

value /= value;

value -=10;

g. Given the following decelerations, what result is stored in each of the listed assignment statements?

int iResult, num1 = 25, num2 = 40, num3 = 17, num4 = 5;

double fResult, val1 = 17.0, val2 = 12.78;

i. iResult = num1 / num4;

ii. fResult = num1 / num4;

iii. iResult = num3 / num4;

iv. fResult = num3 / num4;

v. fResult = val1 / num4;

vi. fResult = val1 / val2;

vii. iResult = num1 / num2;

viii. fResult = (double) num1 / num2;

ix. fResult = num1 / (double) num2;

x. fResult = (double) (num1 / num2);

xi. iResult = (int) (val1 / num4);

xii. fResult = (int) (val1 / num4);

xiii. fResult = (int) ((double) num1 / num2);

xiv. iResult = num3 % num4;

xv. iResult = num2 % num3;

xvi. iResult = num3 % num2;

xvii. iResult = num2 % num4;

3) Write a Java statement to accomplish each of the following tasks:

a) Declare variables sum and x to be of type int.

b) Assign 1 to variable x.

c) Assign 0 to variable sum.

d) Add variable x to sum, and assign the result to variable sum.

e) Print “The sum is: “, followed by the value of variable sum.

a) int sum, x; b) x = 1; c) sum = 0; d) sum += x; or sum = sum + x; e) printf("The sum is: %d\n", sum);

4) Combine the statements that you wrote into a Java application that calculates and prints the sum of integer from 1 to 10. Use the while loop through the calculation and increment statements. The loop should terminate when the value of x become 11.

5) Write a java statement or a set of java statements to accomplish each of the following tasks:

a) Sum the odd integers between 1 and 99, using a for statement. Assume that the integers variables sum and count have been declared.

b) Calculate the value of 2.5 raised to the power of 3 using the pow method.

c) Print the integers from 1 to 20, using the while loop the counter variable i. Assume that the variable it has been declared, but no initialized. Print only five integers per line. [ Hint: Use the calculation i % 5. When the value of this expression is 0, print a newline character; otherwise, print a tab character. Assume that this code is an application. Use System.out.println(‘\t’)method to output the tab character .]

d) Repeat part (c), using for statement

1-

int sum;

int counter;

sum = 0;

for (counter = 1; counter <= 99; counter += 2)

sum += counter;

cout << "Sum of odd integers between 1 and 99 is: " << sum << endl << endl;

2-

value = pow (2.5, 3);

cout << fixed << setprecision (2) << setw (10) << value << endl << endl;

3-

int x;

x = 1;

while (x <= 20)

cout << x;

if (x % 5 == 0)

cout << "\n";

else

cout << "\t";

x++;

cout << endl;

4-

for (x = 1; x <= 20; x++)

cout << x;

if (x % 5 == 0)

cout << "\n";

else

cout << "\t";

cout << endl;

6) Write a java program that displays a student's status based on the following codes: Code Student Status 1 Freshman 2 Sophomore 3 Junior 4 Senior Your program should accept the code number as a user-entered input value and based on this value display the correct student status. If an incorrect code is entered, your program should display the string "An incorrect code was entered".

switch (code)

{

case 1:

status = "Freshman";

break;

case 2:

status = "Sophomore";

break;

case 3:

status = "Junior";

break;

case 4:

status = "Senior";

break;

produceCellPhoneBill()

computeTaxes()

calcLocalTax()

calcStateTax()

getUsageInfo()

computerText()

getCustomerInfo()

computerCalls()

printBill()

calcFedTax()
