You are required to confirm the equation by a
simulation. In this simulation, you will consider how the ball moves
in very short time interval Δt.
I. You will assume that Δt is a constant double with a
value of 0.01. You can get the updated position using s = s + v * Δt. The velocity changes constantly—in
fact, it is reduced by the gravitational force of the earth. In a short time interval, Δv = –gΔt, you must
keep the velocity updated as v = v - g * Δt; In the next iteration, the new velocity is used to update the
distance.
You need to run the simulation until the cannon ball falls back to the ground. Your program should take
the initial velocity as an input. Update the position and velocity 100 times per second, but print out the
position only every full second. Also, printout the values from the exact formula s = vi t – (1/2) gt2
for the
comparison. Lastly plot the path that cannon ball will take to get the bonus marks.
Write a program that calculates the occupancy rate for a hotel. The program should start by asking the
user how many floors the hotel has. A for loop should then iterate once for each floor. In each iteration,
the loop should ask the user for the number of rooms on the floor and how many of them are occupied.
After all the iterations, the program should display how many rooms the hotel has, how many of them
are occupied, how many are unoccupied, and the percentage of rooms that are occupied. The
percentage may be calculated by dividing the number of rooms occupied by the number of rooms.
Input Validation: Do not accept a value less than 1 for the number of floors. Do not accept a number
less than 10 for the number of rooms on a floor.
Write a program to plot a graph of function f(x) = x
n + xn-1
. Your program should take a maximum
absolute value of x as well as a positive integer n as input. You will plot a graph for the range [0, x]. You
should label the y-axis according to the maximum value of x.
Implement a calculator using bitwise operators and for loops only. Your program should run correctly
for positive integers only. You calculator should be able to perform following operations.
Basic arithmetic functions (Addition, subtraction, division and multiplication); Square – to compute the
square of the given value and Power – to compute the power of an integer. It should take two int
arguments number and its power.
Using properties of a Maclaurin series
or Taylor series, you can approximate the function cos(x) using the following
formula:
cos(x) ≈ ∑ (−1)

Write your own approximation of cos(x) without using any library methods (such as pow( ) etc.). Your
program should take x (in radians) and an as input. You should make two functions calcTerm( ) and
sumTerms( ) to calculate the value of cos(x). calcTerm( ) function will compute nth term in the sequence.
It should take x and term number as arguments and the return value of the term. sumTerms( ) takes a
single argument term value and should be used to calculate the sum of all terms. Finally, your program
will have a function testFunction( ), you will call it from main to verify whether your function is working
correctly or not.
Write a program that uses a structure Vector. This structure stores an array
V of double numbers, size of array n. This structure contains:
i. Function to input n, and all elements of V.
ii. Function to display n, and all elements of V.
iii. Function to reverse the order of elements of V.
iv. Function to return the element that appears most frequently in the
array.
The program declares a variable of Vector, and applies all functions on it.
Using dynamic array implement the following :
1. Create the list. The list is initialized to an empty state.
2. Determine whether the list is empty.
3. Determine whether the list is full.
4. Find the size of the list.
5. Destroy, or clear, the list.
6. Determine whether an item is the same as a given list element.
7. Insert an item in the list at the specified location.
8. Remove an item from the list at the specified location.
9. Replace an item at the specified location with another item.
10. Retrieve an item from the list at the specified location.
11. Search the list for a given item
Karim runs 10 spaza shops in different suburbs, each named Skuld Huiswinkel. He asks all the storekeepers to record the final day total sales so that he can determine which of his shops has more sales for each day. He has approached you to write a program that will store the name of the location for each shop and the total sales for the day.
3.1 The program should capture the Skuld Huiswinkel name and the corresponding total sales value amount for the day, all in one cin line.
3.2 The program should store the spaza name and the total sales value in two parallel arrays.
(8 Marks)
3.3 The program should keep a running total that will give the total sales from all spaza shops and also show the average sales for the day.
3.4 Before the program closes, it should store all the values of the parallel arrays in a text file named SHW_Sales.txt. Each line in the file must have the shop location name and the sales value, with these 2 items separated by a space
HBL Bank requires account management software. The branch manager met with the software engineers and discussed the details/requirements. According to him, the bank needs to store account title (name), account number, account type and balance for each account entry. You can deposit and withdraw amount. You are required to provide a library that can be utilized in the management system. Analyze the problem, and implement (interface and definitions) using C++ classes. Comment the header file (the interface) so that a manager can understand the functionalities of every public member function. Class should contain a display function to print all information of an account on screen. Create a demo main program to check each and every function. Also create setter/getter and a parameterized constructor with default arguments.
