Write a program that teaches arithmetic to a young child. The program tests addition and subtraction. In level 1, it tests only addition of numbers less than 10 whose sum is less than 10. In level 2, it tests addition of arbitrary one digit numbers (which means that the sum could be more than 10). In level 3, it tests subtractions of one digit numbers with a non-negative difference. Generate random numbers for each of the levels based on its requirements, and get players answers as their response. Verify if the user entered the correct answer. The player will start at level 1, and gets up to two tries per problem. Advance from one level to the next when the player has achieved a score of five points (one point per successful answering the question).

Answer:

Explanation:

The following program is written in Java and creates three levels with the different set of randomly generated arithmetic problems. As the player goes getting more points they advance every 5 points to the next level.

1. Add the following method to the Point class:
public double distance(Point other)
Returns the distance between the current Point object and the given other Point object. The distance between two points is equal to the square root of the sum of the squares of the differences of their x- and y-coordinates. In other words, the distance between two points (x1, y1) and (x2, y2) can be expressed as the square root of (x2 - x1)2 + (y2 - y1)2. Two points with the same (x, y) coordinates should return a distance of 0.0.
public class Point {
int x;
int y;

}
2. Create a class called Name that represents a person's name. The class should have fields named firstName representing the person's first name, lastName representing their last name, and middleInitial representing their middle initial (a single character). Your class should contain only fields for now.
3. Add two new methods to the Name class:
public String getNormalOrder()
Returns the person's name in normal order, with the first name followed by the middle initial and last name. For example, if the first name is "John", the middle initial is 'Q', and the last name is "Public", this method returns "John Q. Public".
public String getReverseOrder()
Returns the person's name in reverse order, with the last name preceding the first name and middle initial. For example, if the first name is "John", the middle initial is 'Q', and the last name is "Public", this method returns "Public, John Q.".
4. Add the following method to the Point class:
public int quadrant()
Returns which quadrant of the x/y plane this Point object falls in. Quadrant 1 contains all points whose x and y values are both positive. Quadrant 2 contains all points with negative x but positive y. Quadrant 3 contains all points with negative x and y values. Quadrant 4 contains all points with positive x but negative y. If the point lies directly on the x and/or y axis, return 0.
public class Point {
private int x;
private int y;

Driving is expensive. Write a program with a car's miles/gallon and gas dollars/gallon (both doubles) as input, and output the gas cost for 20 miles, 75 miles, and 500 miles. Output each floating-point value with two digits after the decimal point, which can be achieved by executing cout << fixed << setprecision(2); once before all other cout statements.

Assume the data link protocol used by NDAS has the following associated characteristics:

An 8-bit ASCII code is used. Each frame has a size (length) of 11936 bits. A half-duplex circuit with a speed of 1 million bits per second is used for transmission. There is a 30-millisecond turnaround time on the half-duplex circuit. Each frame contains 20 overhead (non-user-data) bytes. Assume that the probability of a frame requiring retransmission due to error in transmission is 1 percent. A millisecond is one-thousandth of a second. Also, 8 bits = 1 character = 1byte

Fill in the blanks

K= _________ bits per bytes
M=_________ bytes
C= _________ overhead bytes

Write a program that would determine the day number in a non-leap year. For example, in a non-leap year, the day number for Dec 31 is 365; for Jan 1 is 1, and for February 1 is 32. This program will ask the user to input day and month values. Then it will display the day number day number corresponding to the day and month values entered assuming a non-leap year. (See part II to this exercise below).

In the QuickSort algorithm, the partition method we developed in class chose the start position for the pivot. We saw that this leads to worst case performance, O(n2), when the list is initially sorted. Try to improve your QuickSort by choosing the value at the middle, instead of the value at the start, for the pivot. Test your solution with the Driver you used for homework. Upload the output produced by the Driver, and your modified QuickSort source file.

A video game character can face toward one of four directions: north, south, east, and west. Each direction is stored in memory as a sequence of four bits. A new version of the game is created in which the character can face toward one of eight directions, adding northwest, northeast, southwest, and southeast to the original four possibilities. Which of the following statements is true about how the eight directions must be stored in memory?
A. Four bits are not enough to store the eight directions. Five bits are needed for the new version of the game.
B. Four bits are enough to store the eight directions
C. Four bits are not enough to store the eight directions. Sodeen bits are needed for the new version of the game.
D. Four bits are not enough to store the eight directions. Eight bits are needed for the new version of the game.

Write a Python program (rainfall.py) to collect data and calculate the average rainfall over a period of years. The program should first ask for the number of years. Then for each year, the program should ask twelve times, once for each month, for inches of rainfall for that month. At the end, , the program should display the number of months, the total inches of rainfall, and the average rainfall per month for the entire period.

Your program should contain two functions:

(1) rainfall(year): This function takes in a year (integer) as a parameter, and returns two values (totalMonths and totalRainfall). In this function, you need to use nested loop. The outer loop will iterate once for each year. The inner loop will iterate twelve times, once for each month. Each iteration of the inner loop will ask the user for inches (float) of rainfall for that month. After all iterations, the function should return the number of months (totalMonths) and the total inches of rainfall (totalRainfall). (Submit for 4 points)

(2) __main__: In the main, you do the following: (Submit for 6 points)

a. Prompt the user to input the number of years. Reprompt the user if the number of years is 0 or less. Hint: use a while loop.
b. Call rainfall(year) and pass to it the value entered above.
c. Calculate the average based on the returned values from rainfall function.
d. Display the number of months, the total inches of rainfall, and the average rainfall per month for the entire period.

Type two statements that use rand() to print 2 random integers between (and including) 100 and 149. End with a newline. Ex:
101
133
Note: For this activity, using one statement may yield different output (due to the compiler calling rand() in a different order). Use two statements for this activity. Also, srand() has already been called; do not call srand() again.

Code:

#include
#include // Enables use of rand()
#include // Enables use of time()
using namespace std;

int main() {
int seedVal = 0;

seedVal = 4;
srand(seedVal);

/* Your solution goes here */

return 0;
