Use c++ You are given an array of doubles of items in a store that have different prices (see template). Write a program that takes the "percent off" discount as input and outputs discounted item prices on one line in the same sequence you are given, separated by a space (" "). Sample Input 25 Sample Output 375 9.3 70.5 33.75 2.25 60.75 750.675 63.75 67.5 0.75.26.25

In C++, the largest int value is 2147483647. So, an integer larger than this cannot be stored and processed as an integer. Similarly, if the sum or product of two positive integers is greater than 2147483647, the result will be incorrect. One way to store and manipulate large integers is to store each individual digit of the number in an array. Write a program that inputs two positive integers of, at most, 20 digits and outputs the sum of the numbers. If the sum of the numbers has more than 20 digits, output the sum with an appropriate message. Your program must, at least, contain a function to read and store a number into an array and another function to output the sum of the numbers. (Hint: Read numbers as strings and store the digits of the number in the reverse order.)
Write a C++ program that simulates online shopping. Declare a variable cart to be an empty Array. The program should have a loop that continues as long as the user wants to shop. Each time through the loop read in the name, price, and quantity of the item the user wants to add to the cart. After adding an item to the cart, the cart contents should be printed. After the loop print a "Please pay ...” message with the total price of the items in the cart.
Write a C++ program that declares an array myList of 50 components of type integer. Initialize the array so that the first 25 components are equal to the square of the index variable and the last 25 components equal to doubles the index variable. The program then calculates the sum and average of elements. In addition, the program counts elements greater than or equal to average and elements less than average. Output the array so that 10 elements per line are printed. Sample input / output: List Elements: 1 4 9 16 25 36 49 64 81 100 121 144 169 196 225 256 289 324 361 400 441 484 529 576 50 52 54 56 58 60 62 64 66 68 70 72 74 76 78 80 82 84 86 88 90 92 94 96 98 Sum of elements: 6750 Average of elements: 135 Elements greater than or equal to 135 is 13 Elements less than 135 is 37
Take a sorted array of 15 elements of type int and a value x from user, you need to find the ceilingand floor of x. The ceiling of x is the smallest element in array greater than or equal to x, and thefloor is the greatest element smaller than or equal to x. Assume than the array is sorted inascending order. Write a c++ program using functions to find floor and ceiling of x from the given array.Examples : For example, let the input array be {1, 2, 8, 10, 10, 12, 19}For x = 0: floor doesn't exist in array, ceil = 1For x = 1: floor = 1, ceil = 1For x = 5: floor = 2, ceil = 8For x = 20: floor = 19, ceil doesn't exist in array
write a c++ program that asks user to enter a number and then print the number that is maximum time repeated in that number and count how mnay times its repeated. remember that if two numbers are repeated same times then you need to output both of them and total times they are repeated. Do this only using loops and functions. arrays pointers are not allowed. for example:input:122344, digit = 2,frequency=2 digit= 4, frequency = 2
Write a function that is given a list of int id’s as a parameter, the id of the person looked for, and the length of the array. Use the data: Bob 123456 89 Suki 234567 77 Felix 345678 55 Julie 456789 67 The function searches the id array and returns the index of the id or –1 if the id does not exist. The main program outputs the name of the person at that index or a message that the person was not found. The name array (up to length number of students) and id array are declared in function main. Show all the declarations and the actual call. A sample run may look like the following: int SearchPerson(const int id[], int length,int who); Enter the id of the person 345678 That person is: Felix with a mark of 55 Enter the id of the person 444444 That person does not exist. in C++ please use basic coding I'm not…
Given an array of integers of size 10. Write a C++ function that takes the array as a parameter and returns the numbers of elements in the array that are small. A number is called "small" if it is in the range 1..10 inclusive. int ele[10] = {12, 56, -18, 1, 6, 4, 92, 2, 34, 78};; Expected Output: 4

Write a C++ Program that reads a sentence from a file "Sentence.txt" in an array. it also takes input a word "Find" to find and a word "insert" to insert in array. Your task is to find the word and insert the word entered by user in array next to the word found. For Example: Array: The quick brown fox jumps over lazy dog's back. Enter word to find: quick Enter word to insert after: slim After inserting the word updated array is Array: The quick slim brown fox jumps over lazy dog's back
Write a C++ program that will allow you display your name and student number that are stored in a given array. See sample output below.

Write a C++ program that takes an char array of size twenty. Take input a sorted array from the user. Display the char array on console such that each row has only five elements separated by spaces. Then, you are required to then take a char x from the user and use binary search to search for element x in the array. Display the index of the element on the console. Also display two elements before and after the element x. Note: Don't use functions and strings.
Write a c program that asks user to enter car prices and store them into a float array. The program keeps asking the user to enter prices until one of the two things happens: - The user enters number -1 (number -1 shouldn't be inside your array). The total number of prices reaches 50. Then, your program should apply tax rate to the prices. The tax rate is 20% of the car price. Last, you need to find and print the lowest car price before and after applying tax rate. Your program should include and use the following two functions: 1. function calculate_taxes which takes an array and its size as parameters and calculate the tax rate. 2. function find_lowest price which takes the array and its size as input and returns the lowest price.
