List inventory file to screen

[romeoz]

Lets say I have 10 items on my inventory list, I dont want to write this out

inData >> prod >> item >> price >> tax;
cout << prod << "  " << item << "  " << price << "  " << tax << endl;
outData << prod << "  " << item << "  " << price << "  " << tax << endl;

10 times, is there a way to write that out with a ++ sign that once I set something to 10 it knows to print that out 10 times vs. having to oput that statement in 10 times? I want to make it look nice vs. alot of garbage that does not need to be in there.

what about putting it in a loop?

this is my file and I need to get rid of 5 sets of lines...I have 6 sets of lines for 6 products in my Inventory.txt file but I need it to make a loop so I only have to put one set of instructions vs 6 sets for 6 items? Does this make sense?

int itemNum = 10;

for (int count = 0; count < itemNum; count++)
{
     ....
   codes to print data go here
}

The codes inside the loop will be executed "itemNum" times.
You could use while loop also, instead.

I am creating a .H File to store my Array of Inventory Items...I need to be able to reference back to that for the prices and to see if it is taxable or not. How can I design something in my main .cpp file to know how to loko for the prie of that certain product?

As a general rule the .h or .H extension is reserved for header files that contain declarations of functions or classes/structs. To store data in file generated by one run of a program and used in another run of a program at a later time use a file extension like .txt or .dat or some other choice. Use file streams (or file pointers if you prefer C style file handling) to write data to and read data from the given file. You can't use data in the file directly, you need to download it from the file memory to RAM memory you program is using.
