Write a pyhton program and to evaluate polynomials in general and test it on the following: ? 4 − 3? 3 − 39? 2 + 47? + 170 = 0

a) Develop and test a function named evalPoly() that evaluates a polynomial at a given value of the variable. The function receives two arguments: a list of the polynomial coefficients, and the value of the variable. It returns the result of the evaluation as a float. Use your function to evaluate the polynomial at ? = -5.2, -5.0, -1.8, -1.6, 2.6, 2.8, 7.0 and 7.2. What do you conclude about the solutions to the equation above?

b) Write a second function named solvePoly() that seeks a solution of the polynomial between two values of the variable where the function has changed sign. This function should receive the list of coefficients, the two values of the variable between which there is a solution. It should return the value of the variable at which a solution was found. This function may be based on an exhaustive search, a bisection search, or on Newton-Raphson’s method. Select a method with some justification.

Write a python program to read from a file the names and grades of a class of students to calculate the class average, the maximum, and the minimum grades. The program should then write the names and grades on a new file identifying the students who passed and the students who failed. The program should consist of the following functions: a) Develop a gradesInput() function that reads data from a file and stores it and returns it as a dictionary. The function has one argument which is the name of the file where the data is entered. Each line on the file should contain the record of one student holding his or her name and the corresponding grade.

b) Write a second function gradesAssess() that iterates over the dictionary and determines the statistics on the average, minimum, and maximum of the grades and return these statistics as a list.

c) Write a third function gradesReport() that will iterate over the dictionary and write on a new file named Class_Results.txt the names of students whose grades are greater or equal to 60, preceded by the message “Passing Students”. Then the names of students whose grades are lower than 60 should be written on the file, preceded by the message “Failing Students”. Finally, the class statistics should be written on the file, also preceded by the message “Class Statistics”.

d) Write a main program that coordinates the operation of the three developed functions. The program should inform the user of what is its function and request from the user the name of the file where class names and grades are written. Form you own data file, Class_Data.txt that has the following entries : Raja, 90 Yahya, 50 Jad, 70 Hussein, 71 John, 97 Tony, 98 Nasser, 78 Maroun, 70 Pamela, 78 Maroun, 70 Ali, 74 Firas, 85

Write a program in python to calculate the value of cos(?) using its Taylor series expansion:

Programming Project #6: Bowling Team

need to use python

Problem

Expected Duration: 3-4 hours

Prerequisites: None

Knowing that you are a budding programmer, your friends have asked you to create a scoring program for your Saturday bowling league. Your program should take a name, team number, and score for each player, and should deal with any number of players, but have 3 people to a team.
Your program should ignore invalid inputs, and not crash. Your program should print the following lists in columns:

1. the individual names, team and scores in descending order with high scorer at the top
2. the individual names, team and scores in alphabetical order
3. If anyone scores a perfect game, put an asterisk in front of their name.
4. The top 3 teams with the highest total scores and their score
5. Display a congratulatory message showing the individual high score and list who got it.
6. Display a sympathetic message showing the individual low score and who got it.

Last, your program should write each of the lists and the summary information
to a text file called game_results.txt in the same format it is displayed on the screen.

Note: You have the option of using pandas Dataframes in your program. Just make sure the console and file output
has the required structure and format.

Task use c++ and Create Base class task with virtual method Create a pair of derivative classes of architecture, scientist, economist - Define a salary in each of these classes and create a method that prints the salary for each job Create a working object Use dynamic_cast Use typeid Create an object for each job that it will include the number of employees of that type and the method of printing these numbers

1. Design a class based on a modified Customer Structure. Use private and public definitions.

2. Create class methods (Setters and Getters) that load the data values. The Setter methods will validate the input data based on the criteria below and load the data into the class if valid.

       For character arrays, the data must be within the specified data size. (See #3 below)

   For zipCode, the number must be between 0 and 99999.

       City and State need to be converted and stored in uppercase.

To get started loading the c-strings.

Getters

The book does not seem to provide a good example of what a (getter) method that returns a char array should look like. Section 9.9 is very close but uses string as examples instead of c-strings.

The best approach is to return a pointer to the c-string- Described as below:

   char* getName(); // declaration - also known as prototype

// Customer is my Class name 

char* Customer::getName() {  // defined member function - Return a pointer to the c-string
    return name;
}

cout << YOUR_INSTANCE_HERE.getName() << endl;

Setters

As for creating a setter method - you can define unsized char arrays in the method header

bool Customer::setName(char inputName[]) {

// code here..

}

3. Write a program that will allow me to enter data for the class and create and call a method that displays the data for the class.

During the input process, pass the input data to the setter method and confirm that the data entered is valid based on the class method return value. If not valid,prompt for me to re-enter the data until it does pass the class method's validation.(A do-while loop works well for this situation) I only need to enter the data for 1 instance of the class. The best way to do this is for the setter methods to return bool instead of void. If the data is valid, return true. Otherwise return false.

There is no need to loop for multiple instances of the object. Do not use cin statements inside the class method definitions.

Below is the original structure to use to create your class definition.

const int NAME_SIZE = 20;
const int STREET_SIZE = 30;
const int CITY_SIZE = 20;
const int STATE_CODE_SIZE = 3;

struct Customer {
    long customerNumber;
    char name[NAME_SIZE];
    char streetAddress_1[STREET_SIZE];
    char streetAddress_2[STREET_SIZE];
    char city[CITY_SIZE];
    char state[STATE_CODE_SIZE];
    int zipCode;

};

Hints: The const variables need to be defined outside of the class definition.

          All access to the data in the class must use public methods that you define. DO NOT DIRECTLY ACCESS the customer data items.

          The class level input methods should return a boolean to confirm the data was loaded and passed any size or data ranges. The customerNumber setter does not need to return a value - It can be a void setter.

          Set the customerNumber to 1 via the code - not user input. There is no input loop so only 1 set of customer's data is to be entered.

Write a python program to evaluate polynomials in general and test it on the following polynomial: ? 4 − 3? 3 − 39? 2 + 47? + 90 = 0

a) Develop and test a function named polyCalc() that evaluates a polynomial at a given value of the variable. The function receives two arguments: a list of the polynomial coefficients, and the value of the variable. It returns the result of the evaluation as a float. Use your function to evaluate the polynomial at ? = -5.4, -5.2, -1.2, -1.0, 2.0, 2.2, 7.2 and 7.4. What do you conclude about the solutions to the equation above?

b) Write a second function named polySolve() that seeks a solution of the polynomial between two values of the variable where the function has changed sign. This function should receive the list of coefficients, the two values of the variable between which there is a solution. It should return the value of the variable at which a solution was found. This function may be based on an exhaustive search, a bisection search, or on Newton-Raphson’s method. Select a method with some justification.
