Write an 8088/8086 assembly program that counts the length of a null terminated string that starts at location STR.print The result on the screen Assume string length will not exceed 255 character.

The purpose of this question is to develop a web page to determine if two line segments represent the diagonals of a square or not. The first line segment L1 is bounded by the two points (x1, y1 ) and (x2, y2 ) while the second line segment L2 is bounded by the two points (x3, y3 ) and (x4, y4 ).

Keep in mind that the lengths of the diagonals of a square are equal and bisect each other at right angles. So you need to find the length, slope and midpoint of each line segment in order to determine if they represent the diagonals of a square or not. Remember that two line segments are perpendicular if the multiplication of their slops equals -1.

In this question you might need to search for formulas in some math textbooks or in the e-library to calculate the slope, x coordinate and y coordinate of the midpoint and length of a line segment.

The web page should be implemented by using HTML tags and PHP codes.

The designed web page should include a title, a header, an input form for entering the values of the four points, only numerical values, and an output form for presenting the slopes, lengths, midpoints of the two line segments and the error messages if any. The design and the layout of the web page are left intentionally for the student to distinguish his/her TMA form other students and to show his/her creativity in designing the web page.

The PHP part should include at least four PHP functions; three functions for calculating the slope, coordinates of the midpoint and the length of a line segment. And another function for determining if two line segments represents the diagonals of a square or not.

CSCI 3000 Homework 5

In this homework, you will manage the car data of a dealer. First, you will design a C++ class called Car. A single Car variable (object) have five member variables (attributes): VIN, make, model, year, and price.

Car class attributes should be private, and set/get functions should be implemented to access and update the values. Also, you should have at least two constructor functions to initialize Car objects. Finally a print() function should be implemented to print single Car data on the screen.

Class description is given below:

Once your class is ready, you will read the “cardata.txt” file, which includes all 250 cars in the dealer. A sample view of the file is given below:

…

Before you read file, you will create an array of cars having size of 250. This number is always 250 and does not change. In the file, each line contains a single car, for which attributes are separated by space character. So, you can read one line using a simple while loop such as:

     While(inputFile >> VIN >> make >> model >> year >> price){

           //create new car and send it to the corresponding array index

...

}

Once your car array is ready, you will provide following operations to the user in a menu.

1. Print All Cars: Print all information of all Cars
2. Print by Make: Get the model name from user and print all cars only in that model.
3. Print by Price: Get a price input from the user and print all cars that have less than given input.
4. Exit: Exit from the program.

You can write your code (including the car class definition and main function) in a single cpp file and submit that file. If you can separate the class files from the main program, you will get extra 10 points for the assignment. In that case, you will need to submit three files such as, “car.h”, “car.cpp”, and “main.cpp”. I will show you how to separate class files from main program in class.

On the top of your source code, please add your name and number, Course ID, HW number and the date using a comment block. Please see the example below,

Include getter and setter methods for the name and age. Include a method to compute and return the age of the dog in “person years” (seven times the dog’s age). Include a toString method that returns a one-line description of the dog. Create a Tester class called Kennel, whose main method instantiates and updates several Dog objects.

Girl?

Jojo is looking for his love by sending messages to strangers on a dating application. Because he knows that many people are using fake profile photos, he found a way to find out the gender of the user by their user names. If the number of distinct characters in one’s user name is even, then she is a female, otherwise he is a male. Help him to find out their gender! '

Format Input:

The first line is an integer T representing the number of test cases. The next T lines each consist of a string S representing the user name in the dating application.

Format Output:

For each test case output “Case #X: ”, where X is the case number, followed by “Yay” if the user is a female, or “Ewwww” if the user is a male.

Constraints

• 1 ≤ T ≤ 100

• 1 ≤ |S| ≤ 105

• S only consist of lowercase letter.

Sample Input 1 (standard input):

1

abb

Sample Output 1 (standard output):

Case #1: Yay

Sample Input 2 (standard input):

2

abbc

za

Sample Output 2 (standard output):

Case #1: Ewwww

Case #2: Yay

Note:

On the first sample input, first test case, the user is female because there are 2 different letters namely “a” and “b”, so the output is “Yay”.

note : USE C language, integer must be the same as the constraint, DONT USE VOID, RECURSIVE(RETURN FUNCTION), RESULT, code it under int main (must be blank){
