Arrays and storing values

i am writing a program whereby i have written the instructions the shell of the program, and have written code for inputting values, but how do i collect all the information i have inputted. I am aware it involves arrays but can you help and point me in the right direction ?

Here is part of my program:

Code:

#include <iostream.h>
#include <string>
#include <conio.h>
main()
{
int salescode, bikeprice, modelcode, quantity;
   string date;
   char answer; //either yes or no


   do
        //the instructions to enter the i.d. code will be repeated (do...while
        //loop) as long as the salescode is less than 1 or greater than 20.
   	{

      	cout << "\n\nPlease enter your identifiction code ";
         cin >> salescode;

         //the condition is tested
         if (salescode < 1 || salescode > 20)

         	{
            	cout << ("\nTHIS I.D. CODE IS NOT VALID. TRY AGAIN \n");
            }
      }
	//the instructions to enter the i.d. code will be repeated (do...while
   //loop) as long as the salescode is less than 1 or greater than 20.
   while (1 > salescode || salescode > 20);

   //another do...while loop
   do
   	{
      	cout << "\nPlease enter the bike price (one unit = 1 Euro) ";
      	cin >> bikeprice;

         if (bikeprice < 1 || bikeprice > 500)

         	{
            	cout << ("\nINVALID PRICE. Bike prices cannot be 0 or more than 500. TRY AGAIN \n");
            }
      }

   while (bikeprice < 1 || bikeprice > 500);

   //another do...while loop
   do
   	{
      	cout << "\nPlease enter the 3 digit model code ";
      	cin >> modelcode;

         if (modelcode < 0 || modelcode > 999)

         	{
            	cout << ("\nINVALID MODEL CODE. TRY AGAIN \n");
            }
      }

   while (modelcode < 0 || modelcode > 999);

   //another do...while loop
   do
   	{
         cout << ("\nPlease enter the quantity sold ");
      	cin >> quantity;

         if (quantity < 1 || quantity > 10)

         {
         	cout << ("\nINVALID QUANTITY. TRY A NUMBER FROM 1-10 \n");
         }
      }

   while (quantity < 1 || quantity > 10);

	do {


			cout << "\nPlease enter the date in this format dd/mm/yyyy: ";
         cin >> date;

			cout << "\nIs this the correct date ?\t" << date << "\tpress y/n: \n\n";
         cin >> answer;   //gets answer from user

			switch (answer)	{
         	case 'y':
            	cout << "\n\n\nThank You!\n\n";
               break;
            }
         }while (answer != 'y');
   }

So if you run my program as it is, how do i store the values entered for each of the commands prompted ?

I will need these values to be used later on to calculate the weekly sales.

Any ideas please ?
oh yeah, if i type in any other non integer, the program crashes.
what would you suggest.

I am new to c++ and programming
Thanks

how do i store the values entered for each of the commands prompted ?

They are already being stored, when you type cin >> salescode it saves the users input into the variable salescode .. all your information is saved in your declared variables

Code:

int salescode, bikeprice, modelcode, quantity;

oh yeah, if i type in any other non integer, the program crashes.

You will have to take input and save it into a string, then examine the string to confirm that all characters are in fact numbers.
There is a method called isdigit which is in <cctype> , so you can make a method called isNum() and it would look like this

Code:

bool isNum(string input)
{
   for(int i=0; i < input.length(); ++i)
   {
   if( !isdigit(input[i]) )
      return false;
   }
   return true;
}

isdigit - C++ Reference

There might be another simply way but I cant think of one.
