c++ homework

Any positive integer number can be expressed as the product of its prime factors. For example, integer number 120=2*2*2*3*5. Write a MAIN function and two FUNCTIONS (name those FUNCTIONS any way you wish) to find the sum of the prime factors of the elements of a two-dimensinal 5X4 integer array A, and store them into a two-dimensinal 5X4 integer array B, and finally, print A and B. Within the MAIN function:· Declare two 5X4 integer arrays A and B. · Initialize array A elements with (x+3) (x starting from 1 and incrementing by 2 for each element of array A). · Pass the array A and its dimensions (number of rows and columns) to the FUNCTON2 as arguments. Be sure that the number of rows and columns should be passed as POINTER arguments. · Pass A, B, number of rows and number of columns to the FUNCTION1 as arguments. · Pass the array B and its dimensions (number of rows and columns) to the FUNCTON2 as arguments. Be sure that the number of rows and columns should be passed as POINTER arguments. Within the FUNCTION1:· Compute and print the prime factors of each element of array A. · Store the sum of the prime factors of each element of array A into the corresponding element of array B. Within the FUNCTION2: Print arrays A and B. PS: No need to take any entry from user. For all calculations, use only the numbers that you generate in matrix A.
