2. Write a program that will load A with 15 random numbers (range : 1-50). Display elements of A in ascending order. Then get a number X. Compare X to each element of A, if array element is less than X, replace that element with X. On another line, display elements of A after replacing all elements less than X with X.
1. Write a program that fills an array with 10 random integer values between O and 100, your program should then calculate and print the alternating sum of all elements in the array. for example, if the array values are (89, 35, 44, 61, 66, 52, 45, 16, 48, 73) then the sum will = 89- 35 + 44 - 61 + 66- 52 + 45 - 16 + 48 - 73 = 55. Sample Run: The generated numbers are: 2 11 44 38 66 72 38 67 43 13 The alternating sum is -8 2. Write a program that reads 10 characters from user and store them in an array. Then display one or more of the following messages: 1. All characters are letters 2. All letters in the list are upper 3. There is no vowel letter in the list 4. There is at least 2 digits in the list 5. There is at least 3 symbols in the list Sample run 1: Enter 10 characters: AB1OK8 M& ? All letters in the list are upper There is at least 2 digits in the list There is at least 3 symbols in the list
Using methods and arrays , write a program that Creates and fills an array A of size 50 filled with random integers in the range 5 to 50 inclusive . prints it out in 5 lines ( 10 values per line ) . • Calculates the sum of the odd elements of A and print it out .

1. Declare an array to hold eight integers. Use a for loop to add eight random integers, all in the range from 50 to 100, inclusive, to this array. Duplicates are okay. Next, pass the array to a method that sorts the array and returns another array containing only the largest and smallest elements in the original array. Print these two values in main. Then use a foreach loop to display all elements of the sorted array on one line separated by a single space. This latter loop should also count the odd and even numbers in the array and determine the sum of all elements in the array. SAMPLE OUTPUT The lowest element is 59 The highest element is 96 Here is the array 59 64 76 77 80 88 91 96 Evens: 5, odds: 3 Total: 631
The Lo Shu Magic Square is a grid with 3 rows and 3 columns shown below. The Lo Shu Magic Square has the following properties: The grid contains the numbers 1 – 9 exactly The sum of each row, each column and each diagonal all add up to the same number. This is shown below: Write a program that simulates a magic square using 3 one dimensional parallel arrays of integer type. Do not use two-dimensional array. 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. Processing Requirements - c++ Use the following template to start your project: #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 //…
