I have a question about this program. I created the header file called util.h and I have completed most of the 3 out of 4 reports that need to be done. This program has 2 arrays, stock1 and stock2 and they each have 20 prices. I need to write functions (1 for stock1 and the other for stock2) to find the 16 5-day moving average of the price of the stocks. This means I would find the average price for prices 1-5, then the average price from 2-6, then 3-7, 4-8, 5-9, 6-10 and so on until I get to 16-20. I am not sure how to do this. I know how to find the moving average, but I don't know how to return the values, or if they need to be returned at all. Anybody have any ideas? Functions can only return 1 value. They can probably return more, but knowing this is beyond the scope of this course. I know that writing 16 functions is absurd. How about pointers, which I am not that good at writing yet? Or can we just have the printf statements within the function? Or am I wrong all together? LOL. Here's the program:

The float movAvg1 will be the function that will find the 16 5-day moving average. I plan on having another function called float movAvg2 to create the 16 5-day moving average for stock2. I appreciate any help.....Thanks....TommyCode:#include <stdio.h> #include <conio.h> #include <process.h> #include "util.h" int numDays1(float stock1[],float stock2[],int); /*function prototype*/ int numDays2(float stock2[],float stock1[],int); /*function prototype*/ int numSame(float stock1[],float stock2[],int); /*function prototype*/ int numAvg1(float stock1[],int); /*function prototype*/ int numAvg2(float stock2[],int); /*function prototype*/ float movAvg1(float stock1[],int); /*function prototype*/ int main() { system("CLS"); /*Clears the screen*/ printf("Report 1\n"); float stock1[]={34.25,40.50,36.50,40.00, 30.25,30.25,35.50,36.00, 34.25,37.00,34.00,35.00, /*Arrays are declared and initialized*/ 36.25,34.25,40.50,41.50, 41.50,40.00,36.50,34.50}; float stock2[]={40.25,38.50,34.50,33.50, 30.50,29.75,37.50,38.00, 34.75,38.00,34.25,37.00, 34.25,37.50,34.50,38.50, 37.50,37.25,38.25,37.50}; printf("\nStock1 has exceeded the price of stock2 by: %d days\n",numDays1(stock1,stock2,20)); printf("\nStock2 has exceeded the price of stock1 by: %d days\n",numDays2(stock2,stock1,20)); printf("\nThe number of days in which the price of the stocks were the same: %d days\n\n",numSame(stock1,stock2,20)); PauseScreen(); system("CLS"); printf("Report 2\n"); printf("\nThe number of days in which stock1 exceeded it's price is: %d days\n", numAvg1(stock1,20)); printf("\nThe number of days in which stock2 exceeded it's price is: %d days\n", numAvg2(stock2,20)); PauseScreen(); system("CLS"); printf("Report 3\n"); printf("\nThe average for prices 1 through 5 are: %.2f\n", movAvg1(stock1,20)); getch(); return 0; } int numDays1(float stock1[],float stock2[],int size) { int index; int days; days; days=0; for (index = 0;index < size;index++) if (stock1[index] > stock2[index]) { days++; } return days; } int numDays2(float stock2[],float stock1[],int size) { int index; int days; days=0; for (index = 0;index < size;index++) if (stock2[index] > stock1[index]) { days++; } return days; } int numSame(float stock1[],float stock2[],int size) { int index; int days; days=0; for (index = 0;index < size;index++) if (stock1[index] == stock2[index]) { days++; } return days; } int numAvg1(float stock1[],int size) { float sum; sum=0; int index; int days; days=0; int avg; avg=0; for (index = 0;index < size;index++) { sum=sum+stock1[index]; } avg=(int)sum/size; for (index = 0;index < size;index++) if (stock1[index]> avg) { days++; } return days; } int numAvg2(float stock2[],int size) { float sum; sum=0; int index; int days; days=0; int avg; avg=0; for (index = 0;index < size;index++) { sum=sum+stock2[index]; } avg=(int)sum/size; for (index = 0;index < size;index++) if (stock2[index]> avg) { days++; } return days; } float movAvg1(float stock1[],int) { float sum; sum=0; int index; int days; days=0; float avg; avg=0.0; for (index=0;index<5;index++) { sum=sum+stock1[index]; avg=sum/5; } return avg; }

P.S.--If anyone has any suggestions on improving my code, I would like to know.
