C++ How do I reprint values from a loop? - c++

Question

I am currently making a cash register that inputs 5 values and then outputs those same 5 values on a receipt with the item tax and subtotal. I then have to add together all the item costs, tax costs and so on to produce a total. So Far I have created code to intake five values and set the frame for my receipt. The issue I have is I have no idea how to get all the values entered from the initial loop and put them on the receipt. The only value that is retained is the final value I input. I'm pretty new so excuse my code and if it's not obvious for myself! Appreciate the help!
#include <cstdlib>
#include <iostream>
#include <iomanip>
using namespace std;
int main() {
double taxRate = 0.07;
double subtotal = 0;
double total = 0;
float item;
float cost;
float counter = 0;
while (counter != 5) {
for (int num=0; num < item; num++) {
}
counter++;
std::cout <<"Enter the cost of the item: ";
std::cin>>item;
}
cout << endl;
cout << setw(10) << "Item Cost"
<< setw(11) << "Item Tax"
<< setw(19) << "Item Subtotal\n";
cout << "----------------------------------------\n";
std::cout.precision(2);
std::cout.setf(std::ios::fixed);
cout << setw(10) << item << setw(11) << item * taxRate<< setw(17) << (item*taxRate)+item << endl;
return 0;
}

You should start by reading on what vectors are and how they work. Get rid of the while loop. You only need 2 for loops to accomplish the task with the way your code is set up.
vector<float> cash;
......
......
for (int i = 0; i < 5; i++)
{
cout << "Enter the cost of the item: ";
cin >> item;
//push items into vector here
}
.....
.....
for (int i = 0; i < cash.size(); i++)
{
// output like you were doing but with your vector elements
}
With that skeleton code you should be able to accomplish what you want with a little research
