in C++ please

Could you please explain how the program works?

Question 04(8 points) Write a program that declares three one-dimensional arrays named volts, current, and resistance. Each array should be declared in main) and be capable of holding 10 double-precision numbers. The numbers to store in current are 10.62, 14.89, 13.21, 16.55, 18.62, 9.47, 6.58, 18.32, 12.15, and 3.98. The numbers to store in resistance are 4, 8.5, 6, 7.35, 9,15.3, 3, 5.4, 2.9, and 4.8. Your program should pass these three arrays to a function named calc_volts(), which should calculate elements in the volts array as the product of the corresponding elements in the current and resistance arrays (for example, volts[1]current[1] * resistance [1]). After calc_volts) has passed values to the volts array, the values in the array should be displayed from within main)
