1. Write a C++ program to accept the size of an array from the user. Then, dymanically create an array of doubles of the given size. Then, add all the numbers in the even indices and subtract all the elements in the odd indices to a running total and print it. For example, if the array were {1,5,8,7} (0 indexed), the total is 1-5+8-7 = -3 Sample Run: Enter the size of the array: 9 Enter the array: 2.5 -4 0.8 1.9 3 -6 1 3.7 4.2 The sum is 15.9
