Programming & Computer Science Answers

Instructions:

1. Input four float numbers; they could be positive or negative.
2. Only add all inputted negative numbers, and print its sum, up to 2 decimal place.
3. Hint: The previous/latest topic is about if-else-elseif statements, but do we need one here?

Input

1. First decimal number

2. Second decimal number

3. Third decimal number

4. Fourth decimal number

Output

The first four lines will contain message prompts to input the four decimal numbers.

The last line contains the sum of all the inputted negative numbers, with 2 decimal places.

Enter the first number: -30.22
Enter the second number: 10.5
Enter the third number: -2.2
Enter the fourth number: -1.8
Sum of all negatives = -34.22

Enter the first number: 50.23
Enter the second number: 100.23
Enter the third number: -123.4
Enter the fourth number: 0.0
Sum of all negatives = -123.40

Instructions:

1. Input three integers.
2. Print the integers in ascending order using your knowledge on conditional statements.

Input

1. First integer

2. Second integer

3. Third integer

Output

The first three lines will contain message prompts to input the 3 integers.

The last line contains the three integers in ascending order.

Enter the first integer: 6
Enter the second integer: 1
Enter the third integer: 3
1 3 6

Did you know that you can also reverse lists and group them according to your liking with proper code? Let's try it to believe it.

Instructions:

Create a variable that accepts a positive odd integer.

Create an empty list. Then, using loops, add random integer values into the list one by one. The number of values to be stored is dependent on the inputted odd integer on the first instruction.

Reverse the order of the list. Then, print out the list's new order in this manner:

[first-half values]-[middle value]-[second-half values], just like that of the sample output. Make use of list slicing that you’ve learned from the past lessons to easily achieve this segment.

Input

The first line contains an odd positive integer.

The next lines contains an integer.

Output

A line containing a list.

[2,5]-[4]-[3,1]

Create a frame. Place two textboxes in the frame using any appropriate layout. Then place four buttons with the button title +, -, * and /. If the user should put two numeric values in the text fields and click any of the button, then a corresponding calculation ( addition, subtraction, multiplication or division) should be shown in a JOptionPane Message Dialogue popup. If the user mistakenly provides any non numerical values in the textbox then a message "Input should be numerical. Please try again" should be shown in a 

JOptionPane Message Dialogue popup.

An example program if only addition and subtraction buttons has been given attached. It doesn't check for wrong input type. In your submission you must check for wrong input type and a message should be displayed accordingly

Write a java program to create an Account class and define constructors in it. Inherit Saving_Bank_Accountclass andCurrent_Bank_Account class from the Account class. Override constructors of Account class in Saving_Bank_Account and Current_Bank_Account classes. Define appropriate methods to operate these accounts. Make necessary assumptions. Give proper comment in your program to increase redability.

1) write a program for the development board that measures gravitational acceleration in 3-axes and displays the values on the LCD screen.

The program will do the following:

a) To be run upon initialization (i.e. implement this in the setup() function)

• Initialize the development board

• Sound the buzzer

• Write the message “ACCELEROMETER” on the LCD screen.

• Wait two seconds

• Sound the buzzer

Provide the following methods in the ExpenseLedger 1. void addExpense(description, amount): You should be able to figure out the serial of the expense yourself. This method will create an expense item and add it to the ledger 2. int removeSmallExpenses(double amt):This method will find the expense items that are smaller or equal to the amount amt and then remove these items from the list. Note that multiple items can be smaller than this value and thus each of these should be removed. Also this method should return the number of items removed. 3. double totalExpenditure(): This method will calculate the total expenditure recorded in the ledger so far. You can do this by iterating through the expenses list and adding all the amounts to find the total expenditure so far. 4. Override the toString method so that the ledger is printed in a well formatted way
