1. Write a C++ program that reads a student grade from the screen/keyboard. The program should then use the input grade as a search key to look for the list of students with matching grade in a text file (file.txt). Each record of the student data in the text file consists of matric number and grade. Print the list of matric numbers for students whose grades match the search key value and the number of students with grades A, B, C, D and F on the screen. Do not use array in the program. An example of the text file (file.txt) is as follows. 66756 A 78954 B 64528 A 59576 F 87412 A 76532 B 79475 C 73645 B 67355 A 88756 C 63849 A If the input grade (i.e. the search key) is A, the input/output screen produced should be displayed as follows. Underlined and bold item is user input. Enter grade (search key): A 56700 D 93769 A The matric number of students with grade A: 66756 64528 87412 63849 93769 67355 Number of students with grade A: 6 Number of students with grade B: 3 Number of students with grade C: 2 Number of students with grade D: 1 Number of students with grade F: 1

3. Laramie Park District has files of participants in its summer and winter programs this year. Each file is in participant ID number order and contains additional fields for first name, last name, age, and class taken (for example, Beginning Swimming). a. Design the logic for a program that merges the files for summer and winter programs to create a list of the first and last names of all participants for the year in ID number order. b. Modify the program so that if a participant has more than one record, the participant's ID number and name are output only once. c. Modify the program so that if a participant has more than one record, the ID number and name are output only once along with a count of the total number of classes the participant has taken.
C++ Problem!! Sort A List Of Integers Given a file of 100,000 unsorted integers, write a program that first prompt user to enter file name and reads those integers into an array and sorts the integers in the array. The program should then prompt the user for an index, and then display the integer at that index. For example, if the array contains ten integers and the contents are 79 4 42 51 12 22 33 17 91 10 after sorting, the integer at index 6 is 42 Download the "List of 100,000 Unsorted Integers" from below link and sort that list, then enter the value at index 10000 (ten thousand) for a screenshot. https://1drv.ms/t/s!AuFS4mkcuYyBjHZ_SIudb93bq2uy?e=CsyvZj
DescriptionWrite a program to compute average grades for a course. The course records are in a single file and are organized according to the following format: each line contains a student's first name, then one space, then the student's last name, then one space, then some number of quiz scores that, if they exist, are separated by one space. Each student will have zero to ten scores, and each score is an integer not greater than 100. Your program will read data from this file and write its output to a second file. The date in the output file will be nearly the same as the data in the input file except that you will print the names as last-name, first-name; each quiz score, and there will be one additional number at the end of each line:the average of the student's ten quiz scores.Both files are parameters. You can access the name of the input file with argv[1]. and the name of the output file with argv[2].The output file must be formatted as described below: 1. First and last names…
1. Write a program in C/C++ that reads a table of data from an input file and displays the data. The program then prompts the user to see the data in specific order. The output of your program should display the sorted data (descending order) according to the user selection. Your program should display the prompt repeatedly until the user wants to exit. See the test run. The input file contains four data fields: Country, Total cases, New cases, and Total deaths. The number of rows (data) can vary between 5 to 100. You must use Quick sort in your implementation. Example test run: Country Total Cases New Cases Total Deaths USA 48072665 70590 784775 India 34447536 10560 463655 Brazil 21960766 2799 611384 UK…
Help me homework c++ The shots file holds a list of shots (imagine some hitscan weapon in a video game like a shotgun or something). Each shot has an origin and a direction. The origin is an (x,y) coordinate, like (5,3). The direction is a slope and whether the shot is traveling along that slope or in the reverse. A slope of "Vertical" means that the shot is travellingstraight up and down. The format is:x_location y_location slope(either a number like 2.1 or a non-number meaning"Vertical") forwards(1 meaning forwards, 0 meaning backwards) 0 0 0 00 0 0 10 0 Vertical 00 0 Squirrel 110 10 -1 1-10.1 -100.01 2.1 0 The first line is a horizontal line shooting left from the origin (0,0).The second line is a shot also travelling horizontally from the origin, but forward along the x axis instead of backwards.The third line is shooting straight down out of the originThe fourth line is shooting straight up out of the origin (any non-number means Vertical, not just Vertical)The fifth line is…
Use C++ Language Problem 2 (Save and Get Info): Write a program that asks for the user's name, phone number, and address. The program then saves all information in a data file (each information in one line) named list.txt. Finally, the program reads the information from the file and displays it on the screen in the following format:Name: User's Name Phone Number: User's Phone Number Address: User's Street Address User's City, State, and Zip Code
Use C++ In a student file, there are names and scores. Find the max score and print out the names of the students with the max score. • You must get a filename as standard input. See two sample outputs on the next page. • The number of students in the file is at most 50. • You need to make two arrays (see the next page). 1. Create a string array with size 50. The array will store the names of the students. 2. Create an integer array with a size of 50. The array will store the scores of the students.
Write a C++ program that asks the user for a file name and a word for which to search. The program should search the file for every occurrence of the word. When the word is found, the line it contains should be displayed. After all of the occurrences have been found, the program should display the number of times the word was found in the file.
Given a text file containing the availability of food items, write a program that reads the information from the text file and outputs the available food items. The program first reads the name of the text file from the user. The program then reads the text file, stores the information into four separate lists, and outputs the available food items in the following format: name (category) - description Assume the text file contains the category, name, description, and availability of at least one food item, separated by a tab character ('\t'). Ex: If the input of the program is: food.txt and the contents of food.txt are: Classic ham sandwich Available sandwich Chicken salad sandwich Not available Classic cheeseburger Cheeseburger Not available Salads Water 16oz bottled water Available Caesar salad Chunks of romaine heart lettuce dressed with lemon juice Available Salads Asian salad Mixed greens with ginger dressing, sprinkled with sesame Not available Beverages Beverages Mexican food…
