(Address book) Write a program that stores, retrieves, adds, and updates addresses as shown in Figure 17.20. Use a fixed-length string for storing each attribute in the address. Use random access file for reading and writing an address. Assume that the size of name, street, city, and zip is 32, 32, 20, 2, 5 chars, respectively

Store the cars and colors in ArrayLists of type String. When the while loop completes, use a for loop to print out the car and color as shown below: Enter a car or 'done if done: Camry Enter color of car: White Enter a car or 'done' if done: Accord Enter color of car: Blue Enter a car or 'done' if done: done car: Camry, color: White car: Accord, color: Blue
Please do this in C++ 9.18 LAB: Movie show time display Write a program that reads movie data from a CSV (comma separated values) file and output the data in a formatted table. The program first reads the name of the CSV file from the user. The program then reads the CSV file and outputs the contents according to the following requirements: Each row contains the title, rating, and all showtimes of a unique movie. A space is placed before and after each vertical separator ('|') in each row. Column 1 displays the movie titles and is left justified with a minimum of 44 characters. If the movie title has more than 44 characters, output the first 44 characters only. Column 2 displays the movie ratings and is right justified with a minimum of 5 characters. Column 3 displays all the showtimes of the same movie, separated by a space. Each row of the CSV file contains the showtime, title, and rating of a movie. Assume data of the same movie are grouped in consecutive rows. Hints: Use…
Python 9.11 LAB: Course Grade Write a program that reads the student information from a tab separated values (tsv) file. The program then creates a text file that records the course grades of the students. Each row of the tsv file contains the Last Name, First Name, Midterm1 score, Midterm2 score, and the Final score of a student. A sample of the student information is provided in StudentInfo.tsv. Assume the number of students is at least 1 and at most 20. The program performs the following tasks: Read the file name of the tsv file from the user. Open the tsv file and read the student information. Compute the average exam score of each student. Assign a letter grade to each student based on the average exam score in the following scale: A: 90 =< x B: 80 =< x < 90 C: 70 =< x < 80 D: 60 =< x < 70 F: x < 60 Compute the average of each exam. Output the last names, first names, exam scores, and letter grades of the students into a text file named…
Task 1: Signup SystemIn the StringAssignment.c file there are two global arrays of String namely emailArr and passArr.Implement the function signupUser() that takes two String as input, one for user email and another for password. You need to do the following checks:1. Is the email in valid format? 2. Does the password contain at least 8 characters?3. Does the password have both uppercase and lowercase letters?4. Does the password contain digits?5. Does the password contain any of the special characters ($ # * @)?If any of the checks returns false, the signup will not be successful. In that case you need to show proper error message, and return FAIL_VAL. Otherwise, the signup will be successful if all of these checks return true. In that case show success message, return the array index, and store the user email and thepassword into emailArr and passAarr respectively.N.B. You need to discard duplicate signup.Task 2: Login SystemImplement the function loginUser() that takes two String…

Using C++ complete the following program 10.18: Phone Number ListWrite a program that has an array of at least 50 string objects that hold people’s names and phone numbers. The program then reads lines of text from a file named phonebook into the array. The program should ask the user to enter a name or partial name to search for in the array. All entries in the array that match the string entered should be displayed-- thus there may be more than one entry displayed. Prompts And Output Labels. The program prints the message "Enter a name or partial name to search for: " and then after the user enters a some input and hits return, the program skips a line, and prints the heading: "Here are the results of the search:", followed by each matched string in the array on a line by itself. Input Validation. None.
15: points.cpp) Write a program that reads 10 pairs of Cartesian coordinates from a file called "points.txt" and sorts them by increasing x-values, decreasing y-values, and increasing distance from the origin. Use only one sorting routine. Use an enumerated data type to keep track of the field on which the list is being sorted. The number of pairs should be in a global constant.
Section: Algorithm 7. s] A transport consultant has created a file of information about trips collected from individuals who have participated in a survey. This information includes start_time and end_time variables. One of the items contained in the file is the duration of each trip (that is, end_time – start_time) in minutes. The consultant is trying to work out how to calculate the number of trips with duration greater than 60 minutes (that is, how many trips take longer than an hour) and requires your assistance to develop an algorithm. You can assume that the durations are read one at a time and should only be read until EOF (end of file) is reached. i. ] *Develop a flowchart to show your algorithm, using the diagrammatic conventions described in the lecture. s] What is the likely complexity of your program using big-O notation? ** 11. Clearly point out what the primary parameters are and define your terms.
1.0) head Function Define and implement this function in data_utils.py. Purpose: Produce a new column-based (e.g. dict[str, list[str]1) table with only the first N (a parameter) rows of data for each column. Why: Visualizing a table with hundreds, thousands, or millions of rows in it is overwhelming. You frequently want to just see the first few rows of a table to get a sense you are on the correct path. Function name: head Parameters: 1. dict[str, list[str]]-a column-based table of data that will not be mutated 2. int - The number of "rows" to include in the resulting list • Return type: dict[str, list[str]] Implementation strategy: 1. Establish an empty dictionary that will serve as the returned dictionary this function is building up. 2. Loop through each of the columns in the first row of the table given as a parameter. 1. Inside of the loop, establish an empty list to store each of the first N values in the column. 2. Loop through the first N items of the table's column, 1.…
C++ arrays task The scientist monitors the movement of a particle suspended on the surface of the water and records its coordinates every n seconds. make a program that calculates the minimum, average, and maximum velocities of the particle and the distance traveled by the particle. The first line of the original data file contains the number of particle coordinates m (1 <m <100) and the coordinate capture interval in n (n> 0) seconds. The following lines show the particle coordinates xi and yi (1 <i <m) in millimeters (xi and yi are real numbers). Record the minimum, average, and maximum velocities of the particle and the distance traveled by the particle in the result file.
