Consider the following Processing code: void setup (){ int [] arrA = {1, 3, 5, 7, 9}; int [] arrB = arrA; mystery (arrA, arrB ); println (arrA [2], arrB[2]); %3D void mystery (int [] arr1, int[] arr2){ int [] arrC = new int[arr1.length ]; for (int i= 0 ; i < arrl.length ; i++) arrC[i] = 1; arrl = arrC; } What is printed when the code is executed? Note that the println method takes multiple arguments separated by comma. The argument values passed to the method will be printed to the console separated by a space char.
12.14 Zylab 3 - Single Procedure Call Given an array of at least one integer, write a program to create a new array with elements equal to the power of each element in the original array raised to the index, i.e., P[i] = A[i]^i. For this, write two functions that will be called in main function independently. ● power inputs: element (A[i]) and index (1) • task: returns the value of element raised to index (A[i]^i). } O • newElement inputs: base address of new array P (*P), current size of P (variable k) and the new element (A[i]^i) o task: add the new element at the end. o This function does not return any value (void). O Following is a sample C code to perform the required task. You may modify the code for the functions, but the task performed should not be changed. int main() { // Variable Declaration int *A, *P; int n, k; int pow; // Task of main function P[0] 1; for (int j = k = j; pow // Base addresses of A and P // Lengths of arrays A and B // Return value from power function }…
