代码：

#include "stdafx.h"

int _tmain(int argc, _TCHAR* argv[])
{
    int itemNum;
    float unitPrice;
    int day,month,year;

    do{
        printf("Enter item number:");
        scanf("%d",&itemNum);

        printf("Enter unit price:");
        scanf("%f",&unitPrice);

        printf("Enter purchase date(mm/dd/yyyy):");
        scanf("%d/%d/%d",&month,&day,&year);

        printf("Item\tUnit\t\tPurchase\n");
        printf("    \tPrice\t\tDate\n");
        printf("%d\t$ %1.2f\t\t%4d%02d%02d\n",itemNum,unitPrice,year,month,day);
    }while(year!=);    

    return ;
}

Enter item number:
Enter unit price:13.5
Enter purchase date(mm/dd/yyyy)://
Item    Unit            Purchase
        Price           Date

Enter item number:
Enter unit price:
Enter purchase date(mm/dd/yyyy)://
