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.

C++ please

Code with comments and output screenshot is must. Thank you!

Write a C program that Defines a two-dimensional array of 7 rows and 7 columns Promotes the user to fill the array with integes. Tests whether a two-dimensional array has four consecutive numbers of the same value, either horizontally, vertically, or diagonally, and displays "Pattern Found" if the array contains four consecutive numbers with the same value. Otherwise, display Pattern NOT Found. Here are some examples of the Pattern Found case 0 103161 016 86 0 1 0 10316 1 0103161 0 103161 0168601 01686 01 016 86 0 1 5621 29 5521829 5621629 9621 829 6 5 6119 1 6 5 6119 1 6 56 61 9 1 6 96119 1 1361 4 07 1561 4 0 7 1361 4 07 13914 07 33334 07 3533 4 07 36334 07 3339407

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 an integer variable named maxAllowed and in output prints all elements less than the value maxAllowed from the array given below. Print -1 if all elements are greater than maxAllowed variable.int Array[10] = {67, 49, 11, 90, 123, 98, 8, 176, 34, 102};

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 //…
