Problem: Write a Python program that reads from an input file given by a user students information after a summer semester which allow students to take two courses. The program will calculate the accumulated semester grade point average (GPA) according to the courses grades and the number of credit hours of the courses. The GPA scores are shown in table 1. The accumulate GPA is calculated as the following equation GPAcourse 1 • Creditscourse 1 + GPAcourse 2 Credits.course 2 A Creditscourse1+ Creditscourse 2 Accumulate GPA = The input file contains student id and student name in the first line. The rest lines contain courses information (course code, course credit hours, student grade). Suppose the input files always in the same format as in the given sample inputs in Figures 2 and 3. The program should display the result in an output file with name "result_ID.txt" where ID is the student Id. Your output files should be in the same format as shown in the given sample outputs in Figures 2 and 3. The first line contains student name and id followed by a table of courses information and at the end the accumulated GPA. Figure I shows a sample run on a console window. Table 1 GPA Scores Grade A GPA 4.0 B 3.0 2.0 D 1.0 F 0.0 Enter the file name of a students: st 15577.txt The output file named 'result 15577.txt'has been successfully created.

Write a python application to simulate an Online Book Shop. Notes: Option 1 and Option 2 must display the list of books to the user. The Main function accounts for invalid options. Program displays error message for invalid user option, invalid ISBN number or any invalid title.The programmer can create the book title, price, and ISBN information for the books. Each item consists only one string of comma-separated data: book ISBN number, title, and price. A customer can purchase some books either by ISBN number and/or by title. If the user input an invalid number or book title, the program should display an error message. The user can stop shopping with "checkout" option , which triggers the checkout() function that computes the total cost of the books in the cart. A customer will be provided the following menu option while shopping at the book shop: Option 1. Purchase by ISBN: User can purchase a book by its ISBN number. ISBN stands for International Standard Book Number. This is a...

python Now write another program that reads the text file created in the program above and calculates the user's weekly pay. The program should begin by prompting the user for the regular hourly pay rate. The program should then loop through the file and report the days and hours worked. The program should finish by calling a custom void function named calc_pay that calculates and prints the weekly pay, including overtime, if applicable. By law, weekly hours in excess of 40 should be paid at 1.5 times the regular hourly rate. The calc_pay function takes two arguments, total hours and hourly pay rate, and it must be imported from a separate module file. Note that three outputs are required for the pay.Sample Output 1Enter your hourly pay rate 25.00Here are your hours this weekMonday hours : 10.0Tuesday hours : 8.0Wednesday hours : 12.0Friday hours : 12.0Saturday hours : 8.0You worked 50.0 hours this weekYou worked 10.0 hours overtimeYour hourly pay rate is 25ドル.00 Regular pay :...

just do the first step. and the program should be in python and includ as many different functions as possible .

please code in python You place a pawn at the top left corner of an n-by-n chess board, labeled (0,0). For each move, you have a choice: move the pawn down a single space, or move the pawn down one space and right one space. That is, if the pawn is at position (i,j), you can move the pawn to (i+1,j) or (i+1, j+1). Ask the user for the size of a chessboard, n (integer). Find the number of different paths starting from (0,0) that the pawn could take to reach each position on the chess board. For example, there are two different paths the pawn can take to reach (2,1). Look at the diagrams below to convince yourself of this. You can see the four paths that you can take by move 2. Start -> Move 1 -> Move 2 (0,0) -> (1,0) -> (2,1) (0,0) -> (1,0) -> (2,0) (0,0) -> (1,1) -> (2,1) (0,0) -> (1,1) -> (2,2) Print the board with the number of ways to reach each square labeled as shown below. For example: Enter a board size: 4 1 0 0 0 1 1 0 0 1 2 1 0 1 3 3 1

Computer Science Part C: Interactive Driver Program Write an interactive driver program that creates a Course object (you can decide the name and roster/waitlist sizes). Then, use a loop to interactively allow the user to add students, drop students, or view the course. Display the result (success/failure) of each add/drop.

C++ Programming Language: Enhance the code given by outputting: The largest number of the sequence a0 ,a1 ,a2 , ..., ak. The position of the largest number Test your program for the following values of x: 75, 111, 678, 732, 873, 2048, and 65535. Example: "For example, for the input sequence: 75, 226, 113, 340, 170, 85, 256, 128, 64, 32, 16, 8, 4, 2, 1, the program output should contain the following: The largest number of the sequence is 340 The position of the largest number is 4" Code Given: #include <iostream> #include <iomanip> using namespace std; int main() { long x; int count; long a_n; cout << "Enter a nonnegative integer: "; cin >> x; cout << endl; count = 0; a_n = x; cout << a_n << ", "; while (a_n !=1) { if (a_n %2==0) a_n = a_n / 2; else a_n = 3 * a_n + 1; count++; cout << a_n <<", "; } cout << endl; cout << "The integer k such that a_k = 1 is " << count << endl; return0; }

⦁ Perfect Pizza wants to install a system to record orders for pizza and chicken wings. When regular customers call Perfect Pizza on the phone, they are asked their phone number. When the number is typed into a computer, the name, address, and last order date is automatically brought up on the screen. Once the order is taken, the total, including tax and delivery, is calculated. Then the order is given to the cook. A receipt is printed. Occasionally, special offers (coupons) are printed so the customer can get a discount. Drivers who make deliveries give customers a copy of the receipt and a coupon (if any). Weekly totals are kept for comparison with last year’s performance. ⦁ Write a summary of business activities for taking an order at Perfect Pizza.⦁ Draw a context-level data flow diagram for Perfect Pizza⦁ Explode the context-level diagram in b showing all the major processes. Call this Diagram 0. ⦁ Draw a logical child diagram for Diagram 0 in c for the process...
