Time Calculator – Intro To Programming - JAVA Write a program that asks the user to enter a number of seconds.

• There are 60 seconds in a minute. If the number of seconds entered by the user is greater than or equal to 60, the program should display the number of minutes in that many seconds.

• There are 3,600 seconds in an hour. If the number of seconds entered by the user is greater than or equal to 3,600, the program should display the number of hours in that many seconds.

• There are 86,400 seconds in a day. If the number of seconds entered by the user is greater than or equal to 86,400, the program should display the number of days in that many seconds.

The .JAVA file from your program should be attached to this assignment.

C++

Task 1

Write a program that allocates an array large enough to hold 5 student test scores. Once all the scores are entered, the array should be passed to a function that sorts them in ascending order. Another function should be called that calculates the average score. The program should display the sorted list of scores and averages with appropriate headings.

Input Validation: Do not accept negative numbers for test scores.

Task 2

Modify the program so the lowest test score is dropped. This score should not be included in the calculation of the average.

Task 3

Modify the program to allow the user to enter name-score pairs. For each student taking a test, the user types the student’s name followed by the student’s integer test score. Modify the sorting function so it takes an array holding the student names and an array holding the student test scores. When the sorted list of scores is displayed, each student’s name should be displayed along with his or her score.

C++

In MIPS assembly language, write a function that will display the max and min value in an array. Then write a function to calculate and display the average of all values in an array. This must be done in MIPS assembly language.

I. Create the class Item with the following members:
1. id, a protected variable of type int
2. name, a protected variable of type string
3. price, a protected variable of type double
4. a public non-default constructor which accepts three parameters to initialize the variables above
5. a copy constructor
6. overload the = operator such that both operands are of type Item
7. overload the = operator such that the right operand is of type double. Assign the value of double to the price member

Alameen is a railway system and wants to install Ticket Vending Machines (TVMs) on the platforms of all rail stations in Peshawar. The TVMs will allow the passenger to buy a ticket/pass using cash, coins, debit cards, or credit cards. The interface of the TVMs should be very easy for the passengers to buy their tickets.

This system should be designed in such a way that the passenger first selects the ticket type, transaction mode, and then get a pass/ticket. Passengers can be adult, senior/disabled citizens, child (5-14 years old), high school, or college students. Ticket type can be either a two-hour pass, midday pass, or AM pass (Monday through Friday from 09:30 am to 02:30 pm), a PM pass (noon through the end of service on the date purchased), a day pass, a 7-day pass, or a 31-day pass. There will be no ticket fare for senior or disabled citizens. The only thing they have to show during traveling is the valid ID and ticket. The ticket fare for a child (5-14 years old), high school or college students will be reduced, and they will have to show valid Id along with ticket (reduced fare) to the ticket checking authority.     

The system should restrict the unauthorized users from using the system. The system should be fast enough that it should accept the input from the user in less than 1 second. The system should be fast enough to print the ticket to the user within 3 to 5 secs when user inserts all the required information. The system should be available 24 hours a day and 7 days a week. The system will also be used by the operator to know the cash and coins inside the machine and withdraw or deposit cash when required. The system is designed in such a way to allow admin to generate reports. The reports include how many tickets are sold, the number of transactions, cash or coins collected, change fares, cash, or coins dispensed.    

Read the above-mentioned scenario and answer the following questions which are as follows:

1. Draw a complete class diagram for above-mentioned scenario

In python.

Projectile motion: Write a python program that will ask the user for

     an initial height y0, initial velocity v, launch angle theta, and mass m.

     Create two functions, one that will calculate max height

     of the projectile, and one that will calculate the range. Ask the

    user which one he/she would like to calculate, then present them with

the answer. (use kg, m and m/s)

Give the mask in the dotted-decimal notation:

a. For a block of Class A which results in 32 subnets

b. Which combines 2048 Class C blocks into a supernet

c. For a block of Class B which results in 64 subnets

d. Which combines 16 Class B blocks into a supernet

[Javascript] Create a function(returnObjectFromId(case, ...idNum)) to return the case Object(s) for a given idNum, or list of idNums.

Calling with a single `idNum` value should return the case Object, and return NULL if an id value that's unknown is passed

returnObjectFromId(case, 84838) would return the Object in the cases Array with

an 'idNumber' of id, and use the .find() method of the cases Array to locate items by idNumber.

returnObjectFromId(cases, -23298312) would return null.

returnObjectFromId(cases, 161020, 161021) would return an Array of case Objects

with two elements, matching the id values. We don't add anything to the returned Array,

if any of the ids in the list are unknown.

As an example, the following function would return an Array of 2 case Objects, ignoring the unknown

id(-23298312):

returnObjectFromId(cases, 231321, 241249, -23298312) would return an Array of 2 cases.

example of case object:

case = {

"idNumber": 112319,

"Reported Date": "2020-08-15",

"Episode Date": "2020-07-12",

},

{

"idNumber": 132421,

"Reported Date": "2020-08-12",

"Episode Date": "2020-07-19",

},

...etc
