The value of π can be approximated by using the following series: the following program uses this series to find the approximate value of π. however, the statements are in the incorrect order, and there is also a bug in this program. rearrange the statements and also find and remove the bug so that this program can be used to approximate π. #include #include using namespace std; int main () { double pi = 0; long i; long n; cin > > n; cout < < "enter the value of n: "; cout < < endl; if (i % 2 == 0) pi = pi + (1 / (2 * i + 1)); else pi = pi ? (1 / (2 * i + 1)); for (i = 0; i < n; i++) { pi = 0; pi = 4 * pi; } cout < < endl < < "pi = " < < pi < < endl; return 0; }

Consider the following function main: int main() { int alpha[20]; int beta[20]; int matrix[10][4]; . . } a. write the definition of the function inputarray that prompts the user to input 20 numbers and stores the numbers into alpha. b. write the definition of the function doublearray that initializes the elements of beta to two times the corresponding elements in alpha. make sure that you prevent the function from modifying the elements of alpha. c. write the definition of the function copyalphabeta that stores alpha into the first five rows of matrix and beta into the last five rows of matrix. make sure that you prevent the function from modifying the elements of alpha and beta. d. write the definition of the function printarray that prints any onedimensional array of type int. print 15 elements per line. e. write a c11 program that tests the function main and the functions discussed in parts a through d. (add additional functions, such as printing a two-dimensional array, as needed.)
