(An example of such a file is shown below). Also, the program should copy from values[1 any value which has even sum of digits and its Index Jocation) to two new arrays evenArr[ 1 and idxArr[ J. respectively. In addition, the program must use a function named getValues() that takes 1D array and its size as inputs and returns three outputs: the evenArr[ ] array, the idxArrl1 array and number of values that has been copied. The program should display both arrays before termination hotead 51 33 61 71 411 587 123
