Code the following diagram Progression Class should be taken as abstract class,

think carefully before implementation. Correct Approach will give you maximum

marks.

Class progession

Fields:long first

Long cur

Methods:Progession()

Long firstvalue()

Long nextvalue()

Void print progession()

Inherited classes of progression :

1) class ArithProgression

Fields:long inc

Methods:ArithProgression()

ArithProgression(long)

Long nextvalue()

2) class GeomProgression

Fields:long base Methods:GeomProgression()

GeomProgression(long)

Long nextvalue()

3)class FibonacciProgression

Fields:long prev

Methods:FibonacciProgression()

FibonaciiProgression(long, long)

Long nextvalue()

To complete our program, we define the main function, which performs a simple

test of each of the two classes.

1) Define a class called student that has the following data members:

- int student number

- string student name

- double student average

The following member functions:

- Constructor that initialize the data members with default values.

- set and get functions for each data member

- Print function to print the values of data members.

Define a class called graduatestudent that inherits data members and functions

from the class student, and then declare the following data members :

- int level

- int year

Member functions:

- constructor

-set and get functions for each data member

- Print function.

Define a class called master that inherits data members and functions from

graduatestudent class, and then declare the following data member:

- int newid.

Member function:

- constructor

- set and get function for the data member

- Print function.

Write a driver program that:

- Declare object of type student with suitab le values then print it

accept the degrees of an angle .determine the type of angle and display it

Rearrange Numbers in String

Given a string, write a program to re-arrange all the numbers appearing in the string in decreasing order. Note: There will not be any negative numbers or numbers with decimal part.

def IsNum(s):
    try:
        int(s)
        return True
    except ValueError:
        return False
s = input()
words = s.split()
numbers = []
for x in words:
    if IsNum(x):
        numbers.append(int(x))
if len(numbers) < 2:
    print(s)
numbers.sort(reverse=True)
result = ''
for x in words:
    if IsNum(x):
        result += str(numbers[0])
        numbers = numbers[1:]
    else:
        result += x
    result += ' '
print(result[:-1])

but if we are giving "Narendra52 is 12 years and 5 months old" 52 also should be calculated as a separate number but it is not acting like that

Sam runs a local musical equipment store in your neighbourhood. He has contracted you to create 

an interactive application that will assist him with customer purchases. Create a class named 

Customer Purchases that will contain get and set methods for a customer number, first name, 

surname, product, price and quantity. Create a separate class called Printing that will include a 

method called Print Details, that will print the Customer Invoice. In the Printing class include 

another method called Customer Purchase Report which will display the following information: 

REPORT OPTION 

PERCENTAGE

TAX

15%

COMMISSION

8.5%

DISCOUNT

10%

TOTAL

(Price + Tax) – (Discount + Commission) 

In your main class, capture all the customer purchase details required to produce the reports.

Write a program that reads a file of numbers of type int and writes all the numbers to another file, but without any duplicate numbers.Assume that the numbers in the input file are already ordered from smallest to largest. After the program is run, the new file will contain all the numbers in the original file, but no number will appear more than once in the file. The numbers in the output file should also be sorted from smallest to largest. Your program should obtain both file names from the user

Write a C program that declares an array of structures of type ‘car’. and asks the user to fill in the elements. Once all the structures have been initialized, the program should present a menu to the user so that he can print a certain structure, or modify its elements.
