will write a c++ program that prompts the user to input elements for two 2x2 matrices. Your program should store the elements of each matrix in a 2D array, then, display the product reciprocal of the two matrices. Note: You must use a nested for loop to process the elements of the matrices.

The user enters a non-negative integer array with the number of elements n and each element. The program outputs these elements in ascending order separated by Spaces, with even numbers first and odd numbers second. Input sample: 10 10 9 8 7 6 5 4 3 2 1 Output sample: 2 4 6 8 10 1 3 5 7 9 (please use c++)

I need help making a C++ code. I need help writing a code that displays the roman Number equivalent of any decimal number between 1 and 20. I need the Roman Numerals stored in an array of strings, and the decimal number that the user enters should be used to locate the array element holding ht Roman Numeral equivalent. I also need it to have a loop to continue entering numbers until an end sentinel of 0 is entered.

For this project the program should be made in C++ Write a menu driven program that reads an array of 10 integer from standard keyboard (user) utilizing a loop and outputs the following depending on user's choice Choice 1 - Prints the elements of array Choice 2 - Prints the minimum value of the array Choice 3 - Prints the maximum value of the array Choice 4 - Prints the product of all the numbers utilizing a loop. Choice 5 - Prints the sum of all the numbers utilizing a loop Choice 6- Print the elements of array in a reverse order When the program is done, your program should ask the user if they would like to enter another set of 10 numbers and the program should repeat itself. Input validation: Your program should only accepts integers.

you 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.

you will develop a c++ program to find all the duplicate elements in a character array. Your program should ask the user to input 7 elements (of type char) and display all the duplicates. For instance, if the user enters d a b g a c b, your program should display: a b

Use C++ In part 1 you will be creating a quiz grading program. You will compare the student's answers with the correct answers, and determine passed or not. The program will make use of two parallel arrays. Each array must be able to support up to 30 characters (so you have two arrays of char or unsigned char values, each one with 30 elements). Your program will need to read in the student answer input file name from cin. It will also need to read in the correct answer file name from cin. You should use the >> operator to read from cin and not get or getline. Using get or getline will be more difficult and will require that you filter out white-space characters in your program. The contents of the student input file should be read into one char array. The file will contain up to 30 characters, each character on a separate line of the file. The first line in the input file will contain the students answer to the first question, and so on for up to 30 questions. The answers are A,...

Please solve this C++ program, including ALL the steps shown below:(don't copy from other sources!) Thank you for your help! The program prompts the user to enter a two-dimensional array (2x2) of int numbers. The program prints that array and calls isIdentity() function to check whether the entered matrix is an identity array or not.Identity array: in which all the elements on the main diagonal are equal to 1 and all other elements are equal to 0. The program then calculates the determinant of that array using det() function. The program prompts the user to enter another two-dimensional array (2x2) of int numbers. The program should add the two arrays and print the result using addArrays() function as shown here. Using a Boolean function isequal() the program checks whether the two arrays are equal or not. (Any explanation of the code will be really useful and please don't include any advanced code or coding info from any program other than C++ )

C++ Coding: Nested Loops Create a constant DIM. Set DIM to 7, and use a nested loop to display the following square matrix output. Output Example: - - - X - - -- - - X - - -- - - X - - -X X X O X X X- - - X - - -- - - X - - -- - - X - - -

you will develop a c++ program to sort the elements of a character array in descending order. Your program should ask the user to input 7 elements (of type char) for the array and sort it. For instance, if the user enters d a b e c x g, your program should display: x g e d c b a Note: You cannot use the built-in sort function. Also, you can assume that the user only enters lower-case characters.

attached is sample output needed to complete this C++ assignment. Function definitions needed with the //. please do not use 2d arrays either. Project Description The Lo Shu Magic Square is a grid with 3 rows and 3 columns shown below Write a program that simulates a magic square using 3 one dimensional parallel arrays of integer type. Each one the arrays corresponds to a row of the magic square. The program asks the user to enter the values of the magic square row by row and informs the user if the grid is a magic square or not. ----------------------------------------------------------------- the code template is as follows ---------------------------------------------- #include<iostream> using namespace std; // Global constants const int ROWS = 3; // The number of rows in the array const int COLS = 3; // The number of columns in the array const int MIN = 1; // The value of the smallest number const int MAX = 9; // The value of the largest number // Function...

I want to know how to write this C++ code with comments to help me understand better.

write a c++ program that declares an array that can hold 20 chars. then the program outputs two upper case character which are A & Z(initials). next using a loop the program populates the array with the pair of the initials until the array is full. then the program outputs the array on one line. then the program swaps the contents of the first and last locations in the array and output the modified array on the next line.
