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 (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.

Write C++ code using one dimensional array and for loop to read 4 numbers using cin into an array of size 4. These numbers are 1, -1, 2, 3 After reading these numbers consecutively in the array , your program should provide: How many positive numbers are in the array? (30) What is the average of these positive numbers ? (30) Your results should be displayed using cout.   c++ with comments   Hint: const int N=4; int arr[N]; int i, count =0; double sum = 0, average=0;

can someone help me with this in C++ Given the following input: Array size (positive integer value) Array elements (positive integer values) Write a program that prints whether the array is a palindrome number. A palindrome number is a number that reads the same backwards and forwards. You must implement your solution following the requirements below: a) Do not use cout to print a message before reading the input from STDIN. b) Read the input in the main function. c) Implement a function to print whether all the elements of the array form a palindrome number. You must use a pointer to an integer variable to implement your function. You cannot use square brackets (array notation) inside the function. You can assume that the input will always be valid. Input Output 5 1 2 3 2 1 Palindrome number 5 1 2 1 4 1 Not a palindrome number

C++ HELP In this lab, you're going to be working with partially filled arrays that are parallel with each other. That means that the row index in multiple arrays identifies different pieces of data for the same person. This is a simple payroll system that just calculates gross pay given a set of employees, hours worked for the week and hourly rate. Parallel Arrays First, you have to define several arrays in your main program employee names for each employee hourly pay rate for each employee total hours worked for each employee gross pay for each employee You can use a global SIZE of 50 to initialize these arrays Second, you will need a two dimension (2-D) array to record the hours worked each day for an employee. The number of rows for the 2-D array should be the same as the arrays above since each row corresponds to an employee. The number of columns represents days of the week (7 last I looked) Functions Needed In this lab, you must read in the employee names first because this…
