Stay on the Screen! Animation in video games is just like animation in movies – it’s drawn image by image (called “frames”). Before the game can draw a frame, it needs to update the position of the objects based on their velocities (among other things). To do that is relatively simple: add the velocity to the position of the object each frame. For this program, imagine we want to track an object and detect if it goes off the left or right side of the screen (that is, it’s X position is less than 0 and greater than the width of the screen, say, 100).

Write a program that asks the user for the starting X and Y position of the object as well as the starting X and Y velocity, then prints out its position each frame until the object moves off of the screen. Design (pseudocode) and implement (source code) for this program.

Sample run 1: Enter the starting X position: 50

Enter the starting X velocity: 4.7

Enter the starting Y velocity: 2

X:50 Y:50

X:54.7 Y:52

X :59.4 Y:54

X:64.1 Y:56

X:68.8 Y:58

X:73.5 Y:60

X:78.2 Y:62

X:82.9 Y:64

X:87.6 Y:66

X:92.3 Y:68

X:97 Y:70

X:101.7 Y:72

1 (10 pts) Give a big-θ bound for the solutions of the following recurrence relations. Show work.

(a) T(n) = 8T(n/2) + n^3 + 100n

(b) T(n) = 5T(n/4) + 3n

(c) T(n) = 7T(n/3) + 100n^2

(d) T(n) = 3T(n/3) + 1000√ n

(e) T(n) = T(n − 1) + n^2

Exercise 5.5

PART A

Copy or cut and paste program P5_2.cpp (located below) to a new program called ex55.cpp. Make PI a constant value. Compile and run the program for the following values:

r = 2 cm, h = 10 cm

The correct answer should be:
      The cross-section area of the cylinder is 3.89556 inch-sq
      The side area of the cylinder is 19.4778 inch-sqr

Did you get the correct answer? You didn't! Explain the reason for this logic error in your report. Now add the instruction that fixes the problem (yes, you need just one instruction) and save your file in ex55.cpp file.   HINT: r=r*0.3937; //converting r to inch

PART B

Modify the ex55.cpp to include a new function called total_area that computes the total surface area of a cylinder. The total surface area is the sum of the side area and cross-section area. Call your new program ex56.cpp.

For r=2 and h=10, the total area must be:  23.373383 inch-sqr.

Program P5_2.cpp:

// P 5_2.cpp This program illustrates the local and global variables and call-by-value.
// This program computes the side area and the cross section area of a cylinder
#include
#include
using namespace std;

//Let’s declare first any global constant, if any required

// This variable is defined globally, i.e. it is known to all functions in this program as PI

// To declare a global constant you must write it outside the main() function

const double PI = 3.14159;  

//Now we declare any programmer defined function

double cross_area(double r);                          // Function prototype for function cross_area
double side_area(double r, double h);            // Function prototype for function Side_area

// Start defining the main function

int main(void)
{
     double h, r; //variables local to the main function

      cout << "Enter the radius and the height of the cylinder in Cm ";
      cin >> r >> h;
      cout << endl;
      cout << "Before I do any computation or call any function, I want to let you know that \n";
      cout << "you have entered r = " << r << " and h = " << h << "." << endl;
      cout << "I am planning to use inch, thus in the first function, I will convert r, and " << endl;
      cout << "in the second one I will convert h \n";

      cout << "The cross section area of the cylinder is " << cross_area(r) << " inch-sqr" << endl;
      cout << "The side area of the cylinder is " << side_area(r,h) << " inch-sqr \n\n";

      return 0;
}

// Definition of all programmer defined functions

double cross_area(double r)
{
     //Cross section area includes the disks at the bottom and the top
      r = r * 0.3937; // converting r to inch
      return 2*PI*pow(r,2);
}

double side_area(double r, double h)
{
      double area; //variable local to side_area function
      h = h * 0.3937; // converting h to inch
      area = 2*PI*r*h;
      return area;
}

Write a program that computes the product of two fractions. The user provides 4 input which represent the numerator and the denominator of two fractions and prints the result of the operation. The program uses two functions. One called MultiplyNumerator(…) which calculates the product of the numerators of the fractions, and a second one called MultiplyDenom(…) which calculates the product of the denominator of the fractions. Call your program MultiplyFrac.cpp

Deposit function.

Calculate the Balance - Deposit

If the action is Deposit 'D’, use a deposit function to add funds to the account

Deposit Input

userchoice = input ("What would you like to do?\n")
userchoice = 'B'
deposit_amount = 200

Deposit Output

What would you like to do?
How much would you like to deposit today?
Deposit was $200, current balance is $700.25

1. Write a function called `deposit`.
2. Request from the user the amount to be deposited. This value should be stored in a variable called `deposit_amount`. Use both the `input` and `float` methods in order to ensure the `deposit_amount` is a float value.
3. Calculate a new account balance.
4. The calculation for depositing funds into the account is `account_balance = account_balance + deposit_amount`.
5. Print the new account balance.

#import sys #no need for this module

#account balance

account_balance = float(500.25)

#<--------functions go here-------------------->

#printbalance function

def printbalance():

print("Account balance: $%.2f" % account_balance)

#deposit function

def deposit():

#accessing account_balance variable which is outside the function

global account_balance

deposit_amount=float(input('How much would you like to deposit today?'))

account_balance+=deposit_amount

print('Deposit was $%.2f, current balance is $%.2f' % (deposit_amount,account_balance))

#withdraw function

def withdraw():

#accessing account_balance variable which is outside the function

global account_balance

withdrawal_amount=float(input('How much would you like to withdraw?'))

#withdrawing only if there is enough balance

if account_balance

print('withdrawal_amount is greater that your account balance of $%.2f' % account_balance)

else:

account_balance-=withdrawal_amount

print('Withdrawal amount was $%.2f, current balance is $%.2f' % (withdrawal_amount,account_balance))

userchoice=''

#looping until user enters Q or q

while userchoice.upper()!='Q':

userchoice = input ("What would you like to do? (D/W/B or Q)\n")

#converting to upper case to reduce comparisons

userchoice=userchoice.upper()

#performing operations based on choice

if userchoice=='D':

deposit()

elif userchoice=='W':

withdraw()

elif userchoice=='B':

printbalance()

elif userchoice=='Q':

print('Thank you for banking with us.')
  
else:

print('Not a valid choice')

1. It is January 1 2020 and you have recently started a new company, GreenDrone, that produces flying drones for garden maintenance. You are still at the product development stage but would like to evaluate the financial feasibility of the project. Here are some information about the company: - R&D expenditures. In order to develop the drones, you need to hire an engineer for 5 years at an annual salary of $96,000. The salary is paid monthly at the end of the month in equal amounts, i.e. 96,000/12 per month for the first year. To stay competitive, you expect you will have to grow the annual salary at a rate of 3%, starting the next year. The engineer contract starts today, i.e., on January 1 2020. - Production cost. Once the product is developed in 5 years (January 1 2025), you will start the production of your drones. Each product is expected to cost $265 to produce. The cost is to be paid to the supplier at the beginning of a month. - Pricing and sales. You plan to sell the drones for $325 a unit over the next three years, i.e., until January 1 2028. All sales for products produced in a month are collected at the end of the month. The appropriate discount rate r is 5%, annually compounded. Denoting the quantity of drones sold in a month by Q. How many drones do you need to sell per month to make this project profitable (i.e., generate a positive NPV)?
