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 88756 C 59576 F 87412 A 76532 B 63849 A 79475 C 73645 B 67355 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…
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 Credits.course 1 + 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…
Assume that the following information is stored in a text file called "data.txt". Fill in the blanks in the following C++ code and debug so that it will read the text file above and find a student with a specific ID and print their name and GPA.

Using C++, create a program that reads integers from the file named "123456" and performs the following actions: Define a function named "calculateFileStats" that reads all the integers from the file and displays the following on the console: -The total sum of all numbers in the file -The minimum value of the numbers in the file -The maximum value of the numbers in the file -The average value with 2 decimal places. If the program fails to access the file, display an error message to the user and terminate the program. Close the file once you have finished reading it. Call the function "calculateFileStats" in main. Note: I did not forget to attach an input file. Use your own input code. I am interested in your code. sample run: Total: 30309 Minimum: 1 Maximum: 10 Average: 5.58
create a program in C++ that does the extraction and analysis described above except that the tasks shall be made somewhat simpler. The program shall read from a file "inputdata.txt" containing a name and exactly five values of floating point numbers per line in the file. The first line of the file shall contain the name of the person (first and last) that gathered the data i.e. Joe Jones. The second line of the file shall be the first row of data. Your program will process all the lines in the file as described below. As the program reads each row of data, it shall do two things: it shall keep a running sum of the values read for that row, and shall also write the average of that row to a file "averages.txt". The program will continue reading from the file until it reaches the end of the file. This will entail using a "while" loop and the eof() function that is talked about in Chapter 13 of the text book. The person's name is to be read in at one time using "getline" and stored under…

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
In C Programming Language. - use user-defined functions.- use an array of arrays.- use file pointers- use string processing and character conversions.- use a dynamic memory function calloc() or malloc() - Demonstrate the ability to read a file and process the data. Problem: You are tasked to write a program that will perform a statistical analysis of student records. Your program will open a text file (provided) and store the values read into an array (2d). Your program will then close the input file and process the data. Your program will print out the records to screen and will then print out the average quiz scores per student.For each student in the provided text input file there is a name of up to 20 characters, an id number of five alphanumeric values (n1234), 4 exm grades in order: exm 1 – exm 4.You may use a fixed 2d array size of 80 characters for the input file name. You must use a dynamic array for at least one task in your program. You may declare your filename array using…
(1) Create a cpp file Array Operations under Source files folder. Write a program in C++ to declare an array called mark. This array will store marks of an assessment like practical, assignment or test for 16 students. Therefore, the size of the array should be 16. a. Number of available marks are 10 for ten students, however there are 16 students, therefore, the remaining marks will be read into the program while the program is running. For now, initialize the array with given marks. 7.3 8.6 10.65 16.4 13.5 6.35 17.3 4.4, 8.5, 12.7 b. With reference to unavailability of remaining 6 marks in part a, write codes to read these remaining six marks and add them at the end as you read. c. Write codes to count the numbers above the average. d. Write codes to determine the highest mark a student scored. e. Display all the important data and results with descriptive relevant labels. [At the end of this activity, comment out your program, so that you next program of activity 2 below will…
Write the following in C++
Please,Explain your work. Thank you!
Must be written in C++! 1. Given an array of integers with 10 values, provide the necessary C++ code to sort the array in descending order (must use bubble sort or selection sort) and output them to an output file with at most 4 values per line. The output will go to the file problem1.txt. Do output your name to the output file. Use the following array to test: int arr[10] = {5, 3, 6, 7, 1, 9, 0, 8, 1, 4}; Sample output file (problem2.txt): Generated by [Your name] 9 8 7 6 5 4 3 1 1 0 Test your code on two additional arrays, one of size 15 and another of size 25. Please submit your tests along with your source code. 2. Write a program that inputs a list of real values from a data file, problem2.txt, and print the count, largest value, and smallest value to the screen. Submit both source code and output when using problem2.txt. Here is one sample input file, problem2.txt (there is an extra blank line at the end and you need to create this…
