- Write a program in C++ that reads a list of 10 names from a file and stores them in an array. Next, allow the user to search for the number of instances of a name. The program should prompt a user for a name and output the total number of instances of that name entered to the screen and to a file (see example input and output below). It should continue to prompt for names until the word done is typed in. For this lab, use the string data type as opposed to char to store the names (i.e. don’t use c-strings).

- Write a complete C program that does the following:1) Read the data stored in the file "rec.txt" into an array of records containing the student ids and the student names.2) Sort the array of records following the students' names in alphabetical order and display the sorted names on the screen.3) Prompt the user to search for the student id by the student's name.I was asked to repost the question to get the other parts solved: Write a program using c++ that: includes a function that reads integers consisting of students’ test scores in the range of 0-200 from a file into a one-dimensional array of size 30 includes a function to calculate the mean (add all the scores and divide by the number of scores) includes a function to calculate the median (sort the scores and then find the score in the middle—if there is an odd number of scores, the median is the middle score; otherwise, it is the average of the two middle scores) includes a function to calculate the mode (most frequently occurring score) includes a function to calculate the standard deviation includes a function to determine the number of students having scores in each of the following ranges: 0-24, 25-49, 50-74, 75-99, 100-124, 125-149, 150-174, 175-200 and output each score range followed by the number of students within that range includes a function to print everything to an output…Write a C program that reads an unspecified number of integers from a file called nums.txt ( up to a maximum of 100 numbers ) and stores those numbers in an array. Your program should then print to the screen the number with the maximum sum of divisors as well as its position in the array in main. Your program should include and use the following two functions: 1. function sum_of_divs which takes any integer and returns the sum of its divisors ( e.g. for the number 20 the function should return the value 42 which is 1+2+4+5+10+20). 2. function max_sum_and_pos which takes the array of integers as input and returns both the number (not the sum) with the maximum sum of divisors as well as its position in the array. Example of a Sample Run : Assume that the file nums.txt has the following 6 numbers ( nums.txt can have up to a 100 numbers which means your array size should be defined as 100): 53 61 40 83 49 44 your program should print the following to the screen: The number with max sum of…
- Using OOP, write a C++ program that read an input file and keep an array of counters for the number of letters in each word in the input file.The input file name is Poem.txt and is located in the current directory.The program will define an array of 9 elements stored in the private member variable area of the class: the 0 element will hold the number of words that are 1 letter long the 1 element will hold the number of words that are 2 letters long the 2 element will hold the number of words that are 3 letters long the 3 element will hold the number of words that are 4 letters long ....and so on until the 8 element will hold the number of words that are 9 letters long. The program will read in the contents of the file word by word into a string variable. The program will determine the length of the word - not counting punctuation - and add to the counter stored in the element array that holds that number of letters in length. So, if the word "midnight" is read in, the number of…At the end of this and other textbooks, there usually is an index that lists the pages where a certain word appears. In this problem, you will create an index for a text but, instead of page number, you will use the line numbers. You will implement function index() that takes as input the name of a text file and a list of words. For every word in the list, your function will find the lines in the text file where the word occurs and print the corresponding line numbers (where the numbering starts at 1). You should open and read the file only once Create the python function as part of a python program. The data required for the function should be created in the python program and passed to the function. its an exercise pyrthon problem 6.27In C++ only Implement a program that is able to read in a set of numbers from a file input.csv and compute the average of each "row" inside of the file. Your program should be dynamic, i.e. given any size input file, your program will still be able to compute the average number of each line Your output should display all floating point numbers with 2 decimal places of precision A sample file has been provided for you.
