Im attempting to write a program that will accept seperate sales amounts from the user and then will total the sales and display both the total sales and the sales tax from the sales at the programs end, if you can provide any help or insight i would greatly appreciate it
#include <stdio.h>
#include <stdlib.h>
#define SIZE 9
int main(void)
{
/*initialize */
int a[SIZE]= {0};
int total, sales, tax;
/*input data */
printf ( "Enter sales (enter -1 to end):$ ");
scanf ("%d", a[SIZE] );
while ( a[SIZE] != -1 ){
total = sum_array(a,SIZE) ;
tax = total * .0825;
printf ("Enter sales (enter -1 to end):$ ");
scanf ( "%d", &sales );
}
printf("total = %d\n", sales);
printf("sales tax= %d\n", total);
system("PAUSE");
}
int sum_array(int a[], int num_elements)
{
int i, sum=0;
for (i=0; i<num_elements; i++)
{
sum = sum + a[i];
}
return(sum);
}many thanks
