Basic C++ Application has extra output then it should - c++

Question

So I'm writing a basic application and for some reason when I run the program a bunch of numbers pop up before my intended output. It was working fine until I added the "std::cout" lines to have the outputs only be 2 decimals. The general gist of the application is a program acts as a self-checkout register at a store and lets the user buy 2 items. And yes I know the code probably looks really bad, I'm still super new to C++.
#include <iostream>
#include <iomanip>
using namespace std;
int main()
{
float price1;
float number1;
float price2;
float number2;
float priceofitemplustax1;
float priceofitemplustax2;
float total;
std::cout << std::fixed;
std::cout << std::setprecision(2);
std::cout << price1;
std::cout << price2;
std::cout << priceofitemplustax1;
std::cout << priceofitemplustax2;
std::cout << total;
cout << endl << "Please scan your first item." <<endl;
cin.get();
cout << endl << "How many of that item are you buying? "<<endl;
cin >> number1;
cout << endl << "How much is that item?"<<endl;
cin >> price1;
priceofitemplustax1 = (number1 * price1) * 1.0875;
cout << endl << "So you want " << number1 << " of this item? Adding tax that will be " << priceofitemplustax1 << "."<<endl;
cin.get();
cout << endl << "Please scan your second item."<<endl;
cin.get();
cout << endl << "How many of that item are you buying? "<<endl;
cin >> number2;
cout << endl << "How much is that item?"<<endl;
cin >> price2;
priceofitemplustax2 = (number2 * price2) * 1.0875;
cout << endl << "So you want " << number2 << " of this item? Adding tax that will be " << priceofitemplustax2 << "."<<endl;
cin.get();
total = priceofitemplustax1 + priceofitemplustax2;
cout << endl << "So your final total for this shopping trip including tax is " << total << "."<<endl;
cin.get();
cout << endl << "Your reciept will print below."<<endl;
cin.get();
cout << setw(14) << right << "Number of Item" << setw(10) << right << "Price" << setw(20) << "Price plus tax" << endl;
cout << setw(14) << right << number1 << setw(10) << right << price1 << setw(20) << priceofitemplustax1 << endl;
cout << setw(14) << right << number2 << setw(10) << right << price2 << setw(20) << priceofitemplustax2 << endl;
cout << endl;
cout << endl;
cout << setw(8) << right << "Total is" << setw(10) << total << price2 << endl;
cin.get();
}

Answer 1

std::cout << std::setprecision(2);
std::cout << price1;
std::cout << price2;
std::cout << priceofitemplustax1;
std::cout << priceofitemplustax2; std::cout << total;
here you write 5 floats

Answer 2

The lines
std::cout << std::fixed; // sets a format
std::cout << std::setprecision(2); // sets a format
set the streams output format.
The lines
std::cout << price1; // outputs a number
std::cout << price2; // outputs a number
std::cout << priceofitemplustax1; // outputs a number
std::cout << priceofitemplustax2; // outputs a number
std::cout << total; // outputs a number
print the variables to the stream.
Just remove the variable output lines. Do not accept this answer - Credit goes to manni66
