Binary file - display issue
Code:
#include <stdio.h>
#include <stdlib.h>
#include <ctype.h>
typedef struct{
char code[6];
int year;
char country[26];
} product;
void add();
void display();
void del();
void add()
{
FILE *addPtr;
product p;
char anymore = 'Y';
addPtr = fopen("product.dat","ab");
while(toupper(anymore) == 'Y')
{
printf("Product Code: ");
gets(p.code);
printf("Expired year of the product: ");
scanf("%d",&p.year);
printf("Product country: ");
fflush(stdin);
gets(p.country);
fwrite(&p,sizeof(product),1, addPtr);
printf("Anymore:(Y/N) ?\t");
scanf("%c",&anymore);
fflush(stdin);
}
fclose(addPtr);
system("pause");
system("cls");
}
void display()
{
FILE *disPtr;
product p;
disPtr = fopen("product.dat","rb");
/*
fread(&p,sizeof(product),1, productPtr);
while (!feof(productPtr));
{
printf("Product Code: %s\n",p.code);
printf("Expired year of the product: %d\n",p.year);
printf("Product country: %s\n\n",p.country);
fread(&p,sizeof(product),1, productPtr);
}
*/
while ( (fread(&p,sizeof(product),1, disPtr)) == 1);
{
printf("Product Code: %s\n",p.code);
printf("Expired year of the product: %d\n",p.year);
printf("Product country: %s\n\n",p.country);
}
fclose(disPtr);
system("pause");
system("cls");
}
void del()
{
}
int main()
{
int menu;
do
{
printf("Product Processing System\n");
printf("=========================\n");
printf("1. Add product\n");
printf("2. Display product\n");
printf("3. Delete product\n");
printf("0. Exit\n");
printf("Your choice: ");
scanf("%d", &menu);
fflush(stdin);
system("cls");
switch (menu)
{
case 1:
add();
break;
case 2:
display();
break;
case 3:
del();
break;
}
}while (menu != 0);
}
Issue: It only display the last record rather than all record.
Attachment: product.dat https://www.dropbox.com/s/xeb6ld7l8c5u844/product.dat
How do I fix the code to make it display all records if the records is more than 1 in display function?
