Fill the following code based on green lines request:

// a,b and product are all arrays of size n (or greater) // in each case, only the first n elements of a,b and product are used // a and b have their values read, and are unchanged // the old values in product are ignored, and overwritten. // After this function, each element of product should // contain the product of the corresponding elements of // a and b. // Example if a is {1,2,3,4} b is {3,5,7,9} and n=4, // then after a call to multiplePairwise (a,b,product,4), // product will be {3,10,21,36}. void multiplyPairwise(int a, int b, int *product, int n){
