6. Write a python program to sum the prime numbers existing in an array. For instance, if A = [4, 7, 12, 3, 9], the output should be 10.

IN PYTHON

The main function in Python must always return an int value. True or false?

Input a list of employee names and salaries and store them in parallel arrays.  End the input with a sentinel value. The salaries should be floating point numbers  Salaries should be input in even hundreds.  For example, a salary of 36,510 should be input as 36.5 and a salary of 69,030 should be entered as 69.0. Find the average of all the salaries of the employees.  Then find the names and salaries of any employee who's salary is within 5,000 of the average.  So if the average is 30,000 and an employee earns 33,000, his/her name would be found.  Display the following using proper labels.  i need to do this in raptor.

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 //…
