C program that formats product information entered by the user

Write a C program that formats product information entered by the user. 

The item code can be any number between 100 and 999, price is a dollar amount up to $9999.99

 and date should be in mm/dd/yy format. Save the program in a file named as display.c, 

and submit the file online as your solution to this question. A session with the program should 

look like this: 

 // Product Information Display Program

   #include <stdio.h>

   int main(void)
   {

     // Declare Variables
     int code, day, month, year;
     float price;

     // Prompt user for item code between 100 and 999
     printf("Enter item code between 100 and 999: ");
     scanf("%d", &code);

     // Print error if entry is not in the specified range
     if(code < 100 || code > 999)  {

          printf("error\n");

return 0; }

     // Prompt user for price between 0 and 9999.99
     printf("Enter price between 0 and 9999.99: ");
     scanf("%f", &price);

     // Print error if entry is not in the specified range
     if(price < 0 || price > 9999.99)   {

          printf("error\n");

return 0; }

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

   // Print error if entry is invalid
     if((month < 1 || month > 12) || (day < 1 || day > 31)

|| (year < 1 || year > 9999)) { printf("error\n");
return 0;
}

     // Display what the user entries in proper formatting
     printf("Code\tPrice\t\tPurchase Date\n");
     printf("----\t--------\t------------\n");
     printf("%d\t$%7.2f\t%.2d/%.2d/%.4d",

                                      code, price, month, day, year);

return 0; }
