I need a bit of help with some C++

Here is what I am supposed to do.
Create a program that implements text based characters and inventory items. Allow the user to view the
inventory of the characters. Implement a trading system that allows character to trade items with each
other. Keep a record of each trade. This project will require the use of arrays, functions, structures,
switch statement(s) and loops.
The program will have at least 3 types of objects. Each will be represented by a structure named
accordingly:
Item – Name, quantity, single argument constructor
Character – Name, array of 5 Items, single argument constructor
Record – Names of the traders, Items traded, the quantity, date and time of the trade.
Create additional structures as needed.
The program will have at least 4 global functions:
displayRecords() – Shows past trade information that was stored in records.
showInventory() – Receives a character as a parameter and displays their inventory.
Initialize() - Receives a character as a parameter and initializes their inventory
trade() - Receives 2 characters as parameters and handles a trade between them. Also creates a
record for each trade. Make sure your program can support at least 20 records.
Create additional functions as needed.
Make a global instance of 5 items. Give each item a name using a single argument constructor.
In main() create an array of 5 characters. Each character will have an array of 5 items.
Use the initialize() function to assign each character a random quantity of each item.
Each character will start with 1 - 100 of each item. Use the c++ rand() function to get the value.
Create a switch based menu in main() that provides the user with the following options:
1. Show Characters
2. Show Inventory
3. Show Records
4. Trade items
5. Exit
Implement each of these options using functions.
Validate your input.
Do not let characters trade items with a quantity of zero.
Do not show records that do not exist. Handle the case of no records to show.
Keep all output looking clean and professional.
I know the code doesn't look all that good. I am in the middle of fixing that. My problem lies with the showing of the record. I can't seem to figure it out.
Any help would be appreciated thanks!
Oh, I also no longer need to place the time and date.

not sure what 'sowing' means, ("showing" ?? maybe??)

but you have an array of int:
int records[20]
which you attempt to hit with
records[i].name //no such thing

dhayden (5798)
Record – Names of the traders, ...
I think that means the names of the two traders involved in the trade.
trade() - Receives 2 characters as parameters and handles a trade between them....
Your trade function prompts for multiple trades. move that logic outside the function.

I figured out what it was. I needed 
1

3
4
5
6
7
8
9
 
else if (rCount > 0)
				cout << "------------------------------------------------------------------------------\n";
			cout << "First trader "<< record[i].charName1 
                                       <<" traded " << record[i].num1 << " of their " << record[i].itemTraded1 << " with " << endl;
			cout << "second trader "<< record[i].charName2 
                                     <<" who traded " << record[i].num2 << " of their " 
                                   << record[i].itemTraded2 << endl;
			cout << "------------------------------------------------------------------------------\n";


in my void display()

I also had to add
1

for (int i = 0; i < 20; i++)
			{
				record[i].charName1 = a.name;
				record[i].charName2 = b.name;

				record[i].itemTraded1 = a.item[t].itemName;
				record[i].itemTraded2 = b.item[v].itemName;

				record[i].num1 = u;
				record[i].num2 = w;
			}
			rCount++;


to the end of my void trade so that the items were being placed inside of my array of record.
