Write a C++ program that declares an array alpha of 50 components of type double. Initialize the array so that the first 25 components are equal to the square of the index variable, and the last 25 components are equal to three times the index variable. Output the array so that 10 elements per line are printed.
Write a C++ program that reads 6 real numbers from the user (negative and positivenumbers) into an array, then it does the following: Display all the values of array in reverse order. Find the sum and average of positive numbers of the array and display them. Count negative numbers of the array and display it. Find the minimum value of the array and display it. Find the index of the minimum value of the array and display it.
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.

Initialize the array so that the first 25 components are equal to the square of the index variable (the position that element will occupy), and the last 25 components are equal to three times the index variable. Output the array so that 10 elements per line are printed. For the number at index 5, the value would be 25, which is 5 squared. The 25th index would hold a value of 75, which is 3 * 25.

- This is for C++: Design a program that allows two players to play a game of tic-tac-toe. Use a two dimensional String array with three rows and three columns as the game board. Each element of the array should be initialized with a asterisk (*). The program should run a loop that does the following: Display the contents of the board array. Allows player 1 to select a location on the board for an X. The program should ask the user to enter the row and column number. Allows player 2 to select a location on the board for an O. The program should ask the user to enter the row and column number. Determines whether a player has won or if a tie has occurred. If a player has won, the program should declare that player the winner and end. If a tie has occurred, the program should say so and end. Player 1 wins when there are three X's in a row on the game board. Player 2 wins when there are three O's in a row on the game board. The winning X's or O's can appear in a row, in a…arrow_forwardJava Program - Functions with 2D Arrays Write a function named displayElements that takes a two-dimensional array, the size of its rows and columns, then prints every element of a two-dimensional array. Separate every row by a new line and every column by a space. In the main function, write a program that asks for integer input to be assigned on a 3 x 3 array and call the function displayElements to print the contents on the next line. Input 1. Multiple lines containing integer each line Output R1C1: 1 R1C2: 2 R1C3: 3 R2C1: 4 R2C2: 5 R2C3: 6 R3C1: 7 R3C2: 8 R3C3: 9 1 2 3 4 5 6 7 8 9arrow_forwardUse C++ Programing language. Write a program that simulates a lottery. The program should have an array of five integers named winningDigits, with a randomly generated number in the range of 0 through 9 for each element in the array. The program should ask the user to enter five digits and should store them in a second integer array named player. The program must compare the corresponding elements in the two arrays and count how many digits match. For example, the following shows the winningDigits array and the Player array with sample numbers stored in each. There are two matching digits, elements 2 and 4. WinningDigits 7 4 9 1 3 player 4 2 9 7 3 Once the user has entered a set of numbers, the program should display the winning digits and the player’s digits and tell how many digits matched.arrow_forward
- Write 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_forwardWrite a c++ program for an atm machine. Use an array with maximum number of accounts to be 100. ATM machine performs the following function: 1. create account An account must have a unique id and 4 digit number pin. eg id = "yo" pin = "4444". if the given unique id is already taken ask the user to enter another unique id. also make sure the pin contains numbers only. 2. Login prompt the user to enter id and pin. incase any of the two is incorrect, print an error message saying incorrect pin or id. 3. withdraw withdraw money from the available balance in the account. make sure the user is logged in. 4. deposit deposit money in the account and update the balance. again make sure user is logged in. 5. pin code change. this allows the user to change their pin. ask for previous pin code and then ask to enter new pin code. 6. balance print the balance that is in the account. 7. logout. logout from the system.arrow_forwardProgramming C++ Instructions: Write a C++ program that declares an array alpha of 50 components of type double.
