3. Write a C++ program that reads 10 integer numbers from a file called input.txt and stores them in an array called data. After the user inputs 10 numbers, the program asks him how many of these 10 numbers he wants to sum. For example, if the user enters 3, the program will sum the first 3 numbers only stored in the array.

In Java please,

Using C++ Program: A palindrome is a word that is spelled the same way both forwards and backwards. For example, the word, 'racecar' is a palindrome. Using character arrays, write a program that prompts the user to enter a word from the keyboard and informs the user whether the word is a palindrome or not.

JAVA PROGRAM Homework #2. Chapter 7. PC #13. Name Search (page 492) Read these instructions for additional requirements carefully. Write a program that reads the contents of the two files into two separate arrays. The user should be able to enter a name the application will display messages indicating whether the names were among the most popular. 1. GirlNames.txt and BoyNames.txt contain a list of the 200 most popular names given to girls/boys born in the United States for the years 2000 through 2009. 2. Your application should use an array to hold the names. 3. The program should continue interacting with the user indefinitely unless the user chooses to quit by entering "QUIT" (should be case insensitive). 4. The user should enter a single name and the program will search the name in both lists. The user SHOULD NOT specify whether the search is for girls name or boys name. The program is responsible for finding either or both and telling the user where it found it. 5.…

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

Write a C++ program that uses a 1D array to store 25 students' computer programming grades (total grade 100). The program should not accept incorrect or invalid grades, and the user should be able to enter marks one at a time. Once the user has completed the entry, the program should output the following. a) Maximum grade b) The average grade (sum of all grades/total number of students) c) Minimum grade Write the C++ code in the space provided (Full marks are awarded for a complete solution.)

This is for C++ Design an application that uses three identical arrays of at least 20 integers.  It should call each module on a different array, and display the number of swaps made by each algorithm.  8 Sorting Benchmarks (bubble, selection & insertion sort) The following represents the output from 3 separate files: BubbleSort, SelectSort and InsertionSort.  Don't ask the user to enter any numbers, but 'hard code' the values in the "Original order" as shown.    Original order:26 45 56 12 78 74 39 22 5 90 87 32 28 11 93 62 79 53 22 51Bubble Sorted:5 11 12 22 22 26 28 32 39 45 51 53 56 62 74 78 79 87 90 93Number of location swaps: 89   Original order:26 45 56 12 78 74 39 22 5 90 87 32 28 11 93 62 79 53 22 51Selection Sorted:5 11 12 22 22 26 28 32 39 45 51 53 56 62 74 78 79 87 90 93Number of location swaps: 19   Original order:26 45 56 12 78 74 39 22 5 90 87 32 28 11 93 62 79 53 22 51Insertion Sorted:5 11 12 22 22 26 28 32 39 45 51 53 56 62 74 78 79 87 90 93Number of location…

c++ 6. Write a program which will prompt the user to enter an array of 12 characters. The program should then print the array, and then print the array again, but this time as a 4 colums by 3 rows array.

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

JAVA PROGRAM Lab #2. Chapter 7. PC #11. Array Operations (Page 491) Write a program that accepts a file name from command line, then initializes an array with test data using that text file as an input. The file should contain floating point numbers (use double data type). The program should also have the following methods: * getTotal. This method should accept a one-dimensional array as its argument and return the total of the values in the array. * getAverage. This method should accept a one-dimensional array as its argument and return the average of the values in the array. * getHighest. This method should accept a one-dimensional array as its argument and return the highest value in the array. * getLowest. This method should accept a one-dimensional array as its argument and return the lowest value in the array.   This part of the program is not correct. There should be no Scanner. You should read the file name from the command line.Scanner scanner = new…
