Outputting inputted number from the list of .txt file(FILE HANDLING)

[Vandalism]

I want to make a store like program.
I have my items in my .txt file, outputted it in my program.
I created a new function for a user to pick a reference number he/she will want to buy.
The problem is it only outputs the last inputted number on the program.

Example:
Type the reference number you want to buy: 1
Type the reference number you want to buy: 2

These are the items you want to buy:
[2] Murdered: Soul Suspect $13.49//this is my problem it should be like this

----------------------------------------------------------
These are the items you want to buy:
[1] Assassin's Creed IV: Black Flag $29.99
[2] Murdered: Soul Suspect $13.49

You want to build up a list of all of the user selections and then iterate over that list.
Your block of if's are not in a loop, so it's only ever going to print out one number in its current condition.

edit: rough example:
build up a history of selections:

vector<int> gameSelections;
	int choice(0);

	for (int i = 0; i < b; i++)
	{
		line('=', 80);
		cout << "Type the reference number you want to buy: ";
                // read in as normal but also "remember selection by
                // adding to a collection to refer to later.
		cin >> choice;
		gameSelections.push_back(choice);
	}

then iterate over this list:

for (int no : gameSelections) {	

		if (no == 1)
			cout << "[1]     " << g[0].games << setw(15) << "$" << g[0].price << endl;
		if (no == 2)
			cout << "[2]     " << g[1].games << setw(15) << "$" << g[1].price << endl;
		if (no == 3)
			cout << "[3]     " << g[2].games << setw(15) << "$" << g[2].price << endl;
		if (no == 4)
			cout << "[4]     " << g[3].games << setw(15) << "$" << g[3].price << endl;
		if (no == 5)
			cout << "[5]     " << g[4].games << setw(15) << "$" << g[4].price << endl;
		if (no == 6)
			cout << "[6]     " << g[5].games << setw(15) << "$" << g[5].price << endl;
		if (no == 7)
			cout << "[7]     " << g[6].games << setw(15) << "$" << g[6].price << endl;
		if (no == 8)
			cout << "[8]     " << g[7].games << setw(15) << "$" << g[7].price << endl;
		if (no == 9)
			cout << "[9]     " << g[8].games << setw(15) << "$" << g[8].price << endl;
		if (no == 10)
			cout << "[10]    " << g[9].games << setw(15) << "$" << g[9].price << endl;
	}
}

you could tidy up those if's a lot. firstly by using if else's or an enum.

Thank you very much! It really helped me a lot! ^^

I have one question. I want to add there the total amount of price below. How do i do that since the price is dynamic depending on the user?

[mutexe]

before the for..

int totalCost = 0.0;

then in every for condition (which is why these load of if's is not great) do this:

if (no == 1)
			cout << "[1]     " << g[0].games << setw(15) << "$" << g[0].price << endl;
                        totalCost+= g[0].price; // (use whatever index you're at)
