This lab will exercise your understanding of some of the concepts covered in Chapter 12:dynamic data, arrays, pointer addresses 1. Create a structure called students. The structure should contain:firstname, lastname, gpa. 2. Create a pointer to the student structure and dynamically create an array of thestudent structure, enough for 4 students.Hint: Store the address of the beginning of the array 3. Create a file that contains four rows of data with last name, first name and gpa valueor use the inFile.txt file attached. 4. Using pointer notation only (not array notation []), read the data from the file andstore the data into the structure.After all the data is read and stored, using pointer notation only, output to the console (cout)each student's first name, last name and gpa. Use information messages and ensure the datais displayed properly. 5. Before exiting, delete the dynamically allocated structure array.Complete as much as you can before you leave ensuring what you've completed…
Use the data file “marketing_campaign.csv” for this problem. Note: There are rows at the top of the file that must be skipped. a. Read the data into R and create a subset consisting of the following columns: Education, Marital_Status, Income, Dt_Customer, MntFruits, and Complain. b. Convert the data a type of the following columns: Education Ordered factor (Hint: Level of “2n Cycle” is between Graduation and Master Marital_Status Unordered factor Income Double precision numeric Complain Logical c. Convert the data type of Dt_Customer to Date. d. With proper code check the data types of columns are as stated in (b) and (c).
PLEASE HELP HOW TO FIX THIS?? This is the OUTPUT! rite a C program that will accept 5 records of students such as Student ID, Name, Course and Year Level. The program will apply the concepts of multi-dimensional array in storing the records. The program will also display the summary of records. NOTE:Your source code must display any of the given sample output below.It means your source code should be flexible enough to meet any of the given sample output.Your source code output must be identical to any of the given sample output.It means you have to strictly follow what are the displayed text, labels, casing of characters in the sample output. OUTPUT: Record 1 Student No.: 202100001 Student Name: Naruto Course: CE Year Level: 1 Record 2 Student No.: 202100002 Student Name: Gokou Course: CPE Year Level: 2 Record 3 Student No.: 202100003 Student Name: Luffy Course: COE Year Level: 1 Record 4 Student No.: 202100004 Student Name: Pikachu Course:…
Do not copy paste from any source else downvote Write a void function that will merge the contents of two text files containing chemical elements sorted by atomic number and will produce a sorted file of binary records. The function’s parameters will be three file pointers. Each text file line will contain an integer atomic number followed by the element name, chemical symbol, and atomic weight. Here are two sample lines: 11 Sodium Na 22.99 20 Calcium Ca 40.08 The function can assume that one file does not have two copies of the same element and that the binary output file should have this same property. Hint: When one of the input files is exhausted, do not forget to copy the remaining elements of the other input file to the result file.
9/21/21 Updates are in blue Add the following functionality and menu options to the previous lab Searching - a user should be able to search by ID or by item name create only one menu item for searching a user should be able to enter the name of the item using any case, (for example, sTRolleR) you may wish to store items in all lower/upper case to expedite the search write one search function that can search by ID and name and goes through the array of structs/objects only once show the entire record if found or an appropriate message if not Sorting - sort by any field in ascending order write one function to sort by any field using a parallel array of pointers use Bubble Sort is not the most effective but the easiest to modify. do not copy and paste sort code five times into the same function. sorting using pointers is faster because you have to swap pointers only, which are normally stored in 4 bytes each; it also allows you to preserve the original order of the items write a…

Fill in the following functions in a program that maps GIS data from NYC OpenData CSV files and marks the current location and closest point: getData() that asks the user for the name of the CSV and returns a dataframe of the contents. getColumnNames() that asks the user for the exact name of the columns that contains the latitude and longitude and returns those values as a tuple. Since the NYC OpenData files use different names for the columns in different datasets (such as "Lat", "Latitude", "LATITUDE" for latitude), the program asks for the name of the column as well as the name of the data file. getLocale() asks the user for latitude and longitude of the user's current location and returns those floating points numbers. computeDist() that computes the squared distance between two points (x1,y1) and (x2,y2):(x1-x2)2 + (y1-y2)2 A sample run to find the closest CUNY campus to the Brooklyn Navy Yard: Enter CSV file name: cunyLocations.csv Enter column name for latitude: Latitude…

1. Which of the following statements are correct? (Select all that applies.) Group of answer choices "ABCDEFG" and "XZACKDFWGH" have "ACDG" as a longest common subsequence. If X is of length n, then it has 2^n subsequences. There is a dynamic programming approach to the longest common subsequence problem. 2. What is the correct syntax to create a NumPy array? Group of answer choices np.object([1, 2, 3]) np.createArray([1, 2, 3]) np.array([1, 2, 3]) 3. What is the correct Pandas function for loading CSV files into a DataFrame?

PLEASE SCREENSHOT AND UPLOAD SUCCESSFUL OUTPUT (IN PYTHON ). Assuming the test cases you create in a file is the survey result. Write a program to read the file. In general, the number of records is unknown, the program should be able to process any number of records without abnormal termination. You may declare a large static array or declared a dynamic array after the number of records is known. After data is read, perform the analysis of the following: 1. Count the total number of households included in the survey. Obtain the average, minimum, maximum and median of household incomes, and print them out. 2. Sort the records of households by four-digit id numbers 3. Print all sorted household records as a three-column table, displaying the data for each household. Include heading for the table. 4. Determine the households that have incomes below the poverty level and print the record of all such households. Include heading for the table. All output should be formatted. Then print the…
8.11 LAB: Movie show time display Java Please 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. Ex: If the input of the…
