An electric mountain railway makes four return trips every day. In each trip, the train goes up the mountain and back down. The train leaves from the foot of the mountain at 09:00, 11:00, 13:00, and 15:00. The train returns from the top of the mountain at 10:00, 12:00, 14:00, and 16:00. Each train has six coaches with eighty seats available in each coach. Passengers can only purchase a return ticket; all tickets must be purchased on the day of travel. The cost is $25 for the journey up and $25 for the journey down. Groups of between ten and eighty passengers inclusive get a free ticket for every tenth passenger, provided they all travel together (every tenth passenger travels free). Passengers must book their return train journey, as well as the departure train journey when they purchase their ticket. Passengers can return on the next train down the mountain or a later train. The last train from the top of the mountain has two extra coaches on it. The train times are displayed on a large screen, together with the number of tickets still available for each train. Every time a ticket is booked the display is updated. When a train is full, the word ‘Closed’ is displayed instead of the number of tickets available. Write and test a program for the electric mountain railway. You will need to complete these three tasks. Each task must be fully tested. Task 1 – Start of the day. Write a program to set up the screen display for the start of the day. Initialize suitable data structure(s) to total passengers for each train journey and total the money taken for each train journey. Each train journey must be totaled separately. There are four journeys up and four journeys down every day. Task 2 – Purchasing tickets. Tickets can be purchased for a single passenger or a group. When making a purchase, check that the number of tickets for the required train journeys up and down the mountain is available. If the tickets are available, calculate the total price including any group discount. Update the screen display and the data for the totals. Task 3 – End of the day. Display the number of passengers that traveled on each train journey and the total money taken for each train journey. Calculate and display the total number of passengers and the total amount of money taken for the day. Find and display the train journey with the most passengers that day.
Units of electricity consumption are given in the form of a matrix in source data. You are required to write user-defined functions and create a repeating menu in Python or C++ keeping in mind the following requirements:
- The student’s ID should be displayed at the top of the menu.
- Press 1 to display the bill of slab 1 and slab 2. (Hint: In slab 1, the unit range is 0 to 100, each unit costs Rs.10, and the data of slab 1 is in the first row of the matrix. While in slab 2, the unit range is 101-200, each unit costs Rs.15, and the data of slab 2 is in the second row of the matrix)
- Press 2 to display the bill of slab 3.(Hint: In slab 3, the unit range is 201 to 300, each unit costs Rs.20, and the data of slab 3 is in the third row of the matrix.)
- Press any other key to exit. Instructions to write Python / C++ program: The following function names should be used for consistency. To calculate and display cost for slab 1: costSlab1(); To calculate and display cost for slab 2: costSlab2(); To calculate and display cost for slab 3: costSlab3()
Hexagon is a geometrical shape having six sides while square is a shape which has four equal sides. You are required to write Python or C++ program for hexagon and square having data members and member functions, and create a repeating menu keeping in mind the following requirements: Consider last digit of your CNIC as the length of one side of hexagon.For example, if your CNIC is XY210351532, the last digit will be 2. Calculate area and perimeter of hexagon. (Hint: Area of hexagon= 1.51.732s ; where ‘s’ is the length of one side of hexagon. Perimeter of hexagon= 6s; where ‘s’ is the length of one side of hexagon) Calculate sum of all the angles of hexagon. (Hint: Sum of all the angles of hexagon= 6a; where ‘a’ is the measurement of one angle of hexagon which is equal to 120.) When the input of user is ‘1’, display area, perimeter and sum of all the angles of hexagon. Calculate area and perimeter of square whereas; Length of one side of square=last digit of CNIC + 1. (Hint: Area of square= (length)2; where ‘length’ is the length of one side of square. Perimeter of square= 4*length; where ‘length’ is the length of one side of the square.) When the input of user is ‘2’, display the area and perimeter of the square. On any other input, the program should exit. Use the last digit of your own CNIC. If you do not use it, your marks will be deducted. Write member functions to calculate and display area, perimeter, and sum of angles of the hexagon.
The manager of a building materials delivery service needs a program to check the contents and weight of sacks to ensure that correct orders are made up for delivery. A price for the order will be calculated. Write and test a program for the manager. Your program must include appropriate prompts for the entry of data. Error messages and other output need to be set out clearly. All variables, constants and other identifiers must have meaningful names. You will need to complete these three tasks. Each task must be fully tested. TASK 1 – Check the contents and weight of a single sack Each sack must obey the following rules to be accepted: contain cement, gravel or sand, with a letter on the side for easy identification C - cement G - gravel S - sand sand or gravel must weigh over 49.9 and under 50.1 kilograms cement must weigh over 24.9 and under 25.1 kilograms Input and store the weight and contents for one sack. The contents must be checked and an incorrect sack rejected. The weight must be validated on entry and an overweight or underweight sack rejected. Output the contents and weight of an accepted sack. If a sack is rejected, output the reason(s). TASK 2 – Check a customer’s order for delivery Input and store the number of sacks of each type required for the order. Use TASK 1 to check the contents and weight of each sack. Ensure that the delivery contains the correct number and type of sacks for the order. Output the total weight of the order. Output the number of sacks rejected from the order. TASK 3 – Calculate the price for a customer’s order Extend TASK 2 to calculate a price for an order. Prices for the sacks are as follows: regular price for each sack cement, $3 gravel, $2 sand, $2 discount price for a special pack containing 1 sack of cement, 2 sacks of sand and 2 sacks of gravel, $10 Calculate and output the regular price for the order. Check how many special packs are in the order. If a discount price applies then output the new price for the order and the amount saved.
The manager of a supermarket needs a program to record donations to charity. Each customer has the choice of three charities to donate to, and 1% of their shopping bill will be donated to the chosen charity. Write and test a program for the manager. Your program must include appropriate prompts for the entry of data. Error messages and other outputs need to be set out clearly. All variables, constants, and other identifiers must have meaningful names. You will need to complete these three tasks. Each task must be fully tested. TASK 1 – Set up the donation system Set up a routine that allows: the names of three charities to be input and stored the charity names to be displayed with a number (1, 2 or 3) beside each name a choice of 1, 2 or 3 to be entered to choose the charity, all other entries rejected the value of a customer’s shopping bill to be entered the donation to be calculated three totals to be set to zero ready to total each charity donation TASK 2 – Record and total each donation For a customer’s shopping bill: input a charity choice of 1, 2 or 3 input the value of a customer’s shopping bill calculate the donation add the donation to the appropriate total Output the name of the charity and the amount donated. TASK 3 – Show the totals so far Extend TASK 2 to accept: donations from more customers a charity choice of -1 to show the totals so far Display the charities’ names and the totals in descending order of totals. Calculate a grand total of all three totals. Output ‘GRAND TOTAL DONATED TO CHARITY’ and the amount of the grand total.
The owner of a river boat hire company wants to calculate the daily profits from hiring out 10 rowing boats on the river. Boats are numbered 1 to 10. Boats can be hired for use between 10:00 and 17:00 every day. Write and test a program for the owner. Your program must include appropriate prompts for the entry of data. Error messages and other output need to be set out clearly and understandably. All variables, constants and other identifiers must have meaningful names. You will need to complete these three tasks. Each task must be fully tested. TASK 1 – calculate the money taken in a day for one boat. The cost of hiring a boat is $20 for one hour or $12 for half an hour. When a boat is hired the payment is added to the money taken for the day. The running total of hours hired that day is updated and the time when the boat must be returned is stored. At the end of the day the money taken and the total hours hired is output. No boat can be hired before 10:00 or returned after 17:00. TASK 2 – find the next boat available. Extend TASK 1 to work for all 10 rowing boats. Use the data stored for each boat to find out how many boats are available for hire at the current time. If no boats are available show the earliest time that a boat will be available for hire. TASK 3 – calculate the money taken for all the boats at the end of the day. At the end of the day use the data stored for each boat to calculate the total amount of money taken and the total number of hours boats were hired that day. Find out how many boats were not used that day and which boat was used the most. Provide a report for the owner to show this information.
