Hello all, I am needing to calculate the amounts of the values stored in the arrays within a function. The calculations within the function however have to be done using pointers. I am having trouble figuring out how to return the value calculated and display it within main. This is what I have so far, any help would be great.

Code:#include <stdio.h> double extend (double [], double [], double []); int main () { #define max 10 double price [max] = {10.62, 14.89, 13.21, 16.55, 19.62, 9.47, 6.58, 19.32, 12.15, 3.99}; double quantity [max] = {4, 9.5,6, 7.35, 9, 15.3, 3, 5.4, 2.9, 4.9}; double amount [max]; int i; for (i=0; i<max; i++){ printf ("The amount is %f\n", extend(price, quantity, amount)); } system ("PAUSE"); return 0; } double extend (double price[], double quantity[], double amount []) { int i; double *gPtr, *mPtr, *nPtr; gPtr= price; mPtr= quantity; nPtr= amount; for (i=0; i<max; i++){ *nPtr++= *mPtr++ * *gPtr++; } return (amount); }
