Stack operations

A stack is a linear data structure that follows certain order to perform the operation; the order will be LIFO (Last In First Out) data structure. In the stack data structure elements/items are removed and added only from the top. The topmost stack item/element is pointed by the top pointer and the element which is added to the stack first will get deleted at the last.

Question

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
3
4
5
6.
your output should look like in the following:
6 36
5 25
4 16
39

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…

Create a C++ Program to do the following: Create a .txt file with up to 10 double numbers. Then in your code, create an array to hold 10 doubles. Openthe file. Read each number from the file into a place in the array. Count how many numbers you read. Close thefile.Now, go through the data in the array twice. Don’t go through all 10 elements in the array, only the elementsfor which you have read data. On the first pass, calculate the average of the numbers in the array. (Calculate thetotal, divide by count, that is µ).On the second pass through the data, for each number you should calculate how far it is from the average(number - average), square that, and keep a sum of the squares, that is S.When you’re done, calculate the average of that sum of squares, A. The square root of that number, σ is yourstandard deviation.Print out the average µ and standard deviation σ

Python Problem Description: Kevin is a freelance video producer who makes TV commercials for local businesses. When he makes a commercial, he usually films several short videos. Later, he puts these short videos together to make the final commercial. He has asked you to write the following two programs. A program that allows him to enter the running time (in seconds) of each short video in a project. The running times are saved to a file. A successful test run for this program would be as shown below: A program that reads the contents of the file, displays the running times, and then displays the total running time of all the segments. A successful test run for this program would be as shown below:
