Language: C Write a program where you first read an integer n, then n integers are read from the keyboard and stored in a dynamically allocated array. Then these numbers and their square should be written to a file named squares.txt in the opposite order of their input. So if the user enters 1 2 3 4 6 your output should look like in the following: 6 36 5 25 4 16 3 9 2 4 1 1

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

Python programming help  I need help of question 1 to read a file from persons.txt   Write a program that takes a person’s details (name, age and a city), and writes to a file (persons.txt) using a loop repeatedly. You should write three person’s to the file. The program terminates on entering any key by the user, except on (Y or y) key.  Sample output of the first run of the program is shown below:              Enter name: JohnEnter age: 20Enter city: SydneyData saved:  John 20 SydneyPress (Y or y) to add another person, or any key to exit    Question 1) Write a program that read a file (persons.txt) from previous question given on the top of this question, and shows all the records/lines from the file as a nicely formatted report with a header as shown:    Name                   Age                      City   +---------------------+--------------------+--------------

Java Your program must read a file called personin.txt.  Each line of the file will be a person's name, the time they arrived at the professor's office, and the amount of time they want to meet with the professor.  These entries will be sorted by the time the person arrived.   Your program must then print out a schedule for the day, printing each person's arrival, and printing when each person goes in to meet with the professor.  You need to print the events in order of the time they happen.  In other words, your output will be sorted by the arrival times and the times the person goes into the professor's office. In your output you need to print out a schedule.  In the schedule, new students go to the end of the line.  Whenever the professor is free, the professor will either meet with the first person in line, or meet with the first person in line if nobody is waiting.  Assume no two people arrive at the same time. You should solve this problem using a stack and a queue. You can only…
