Question
use c++ to Write a
- Prompt the user for the number of doubles
- Allocate an array of doubles accordingly
- Ask the user to enter them one by one and store them in the allocated array of doubles.
- Go through the array and save the index of the largest one. (see hint below if you don’t know how to do this)
- Print them back. [ 1 mark] When printing add “<-- Largest” beside the largest number in array.
- Cleanup your code.
- Assume that the user enters input correctly and that your computer has enough memory.

- [hey expert! kindly answer is simple c++ ] :) You are required to write a program that takes input from the user the marks of his programming fundamentals quizzes in an array. You are required to write the program that caters for 10 students. That means the program asks the user to enter 10 quizzes marks for 10 students (use 2 dimensional array). The program calculates the percentage of all 10 quizzes for each student.Based on the percentage, the program should calculate the grade of each student and store it in a char-one dimensional array. The program should also display the grade of the student on the screen. The grade is calculated by the formula percentage>=80 --- grade = A for percentage >=70 and less than 80 ---------- grade = B for percentage >=60 and less than 70--------- grade = C for percentage >=50 and less than 60 ----------grade = D for percentage less than 50 ----------grade= F In the end when all the grades have been calculated the program should…arrow_forwardyou will write a c++ program to input 5 elements (of type int) from the user and store them in an array. Your program should then reverse the array and display it. For instance, if the user enters 1 2 3 4 5 as the five elements of the array, your program should reverse it and display: 5 4 3 2 1 Note: You must use a for loop to process the array.arrow_forwardC++ Can someone help me with this problem? I have been trying it but it still doesn't work. Thank youarrow_forward
- Given a file of unsorted words with mixed case: read the entries in the file and sort those words lexicographically. The program (in c++) should then prompt the user for an index, and display the word at that index. Since you must store the entire list in an array, you will need to know the length. The "List of 1000 Mixed Case Words" contains 1000 words. You are guaranteed that the words in the array are unique, so you don't have to worry about the order of, say, "bat" and "Bat."arrow_forwardPlease use C++. Also, you don't need a header file, just a CPP File. Please make sure the output is exact.arrow_forwardwrite code in c++ pleasearrow_forward
- Use Python code with: "def recolorImage(img,color):" without using cv2 or PIL recolor(img, color) - Changes all non-white pixels of the image referred to by the parameter img to the specified color, and returns a new image with the changes. img is a 2D array of RGB pixels which represent images. color is a list containing 3 integers, each from 0 to 255, representing RGB values. To create a new image use the cmpt120image.getBlackImage() function which returns a new canvas to draw on.arrow_forwardCan someone please explain this C++ code that my classmate did line by line please. Also, incase you needed further explanation the prompt is as follows: Implement an empty integer array of capacity 5. a) Use a loop to input values from the console into the array. b) Use a loop to determine the smallest element in the array. c) Use a loop to determine the largest element in the array. d) Use a loop to output the array. e) Output the smallest and largest elements. Example Output (input in bold italics)[0] = 4[1] = 24[2] = 123[3] = 54[4] = 3 Array: 4 24 123 54 3 Max: 123Min: 3arrow_forwardWrite a C++ program that helps the user plan out their budget. It should ask the user for the most recent 5 things that they bought; it should ask for both the name for the item and its price. Then, print out the following: total money spent, average money spent per item, lowest priced item, and highest priced item. You can assume that each item has a different name and a different price. You must use at least 1 array and you must display all numbers as dollar values (exactly 2 places after the decimal) EXPECTED OUTPUT Welcome to the Budget Helper. What are the last 5 things you bought? Item 1 name: Bananas Item 1 price: 1.5 Item 2 name: Shoes Item 2 price: 45 Item 3 name: Coffee Item 3 price: 2.5 Item 4 name: Metrocard Item 4 price: 120 Item 5 name: Jacket Item 5 price: 89 The total amount you spent is $258The average price per item is $51.60The cheapest item is BananasThe most expensive item is Jacketarrow_forward
