how do i store the data from the partData file and find if the order was successful??????
is this program correct????????
#include <stdio.h>
#include <stdlib.h>
#define MaxWordSize 1000
/*Part Number = PartNume
Selling Price = SP
Quantity in stock = QtyInStock
Order Number = OrderNum
Quantity requested = QtyRequested
partData (file) = pd
orders (file) = ord
report (file) = rpt */
int binarySearch(int PartNum, double SP[], int QtyInStock[], int size){
int lo = 0; int hi = size - 1; int mid;
while(lo <=hi){
mid = (lo + hi)/2;
if(QtyInStock[mid] == PartNum) return 1;
if(QtyInStock[mid] < PartNum) hi = mid - 1;
else
lo = mid + 1;
return 0;
}
}
int orders(int PartNum, double SP[], int QtyInStock[], int size){
int count = 0;
for(int x = 0; x < size; x++){
if(binarySearch(int PartNum, double SP[], int QtyInStock[], int size) == 1)
count = count + 1;
}
return count;
}
int main(){
FILE * pd = fopen("partData.txt", "r");
FILE * ord = fopen("orders.txt","r");
FILE * rpt = fopen("report.txt", "w");
int PartNum;
int QtyInStock;
double SP;
int OrderNum, count = 0;
int QtyRequested;
char myString [MaxWordSize];
double InvoiceTotal = 0, TotalNumOfOrders = 0;
int size = 20;
fgets (myString, 1000, pd);
fgets (myString, 1000, ord);
fscanf (pd, "%d", &PartNum);
while (PartNum != 0) {
fscanf (pd, "%lf", &SP);
fscanf (pd, "%d", &QtyInStock);
fscanf (pd, "%d", &PartNum);
}
fscanf (ord, "%d", &OrderNum);
while(OrderNum != 0){
fscanf (ord, "%d", &PartNum);
fscanf (ord, "%d", &QtyRequested);
count = count + 1;
TotalNumOfOrders = TotalNumOfOrders + count;
InvoiceTotal = SP * QtyRequested;
count = 0;
QtyInStock = QtyInStock - QtyRequested;
fprintf(rpt, "OrderNum: %d \t\t PartNum: %d \t\t QtyRequested: %d \t\t InvoiceTotal: $%4.2f \t\t \n", OrderNum,PartNum,QtyRequested,InvoiceTotal);

}
