Loop accepts first set of input and then reuses that value - c++

Question

I am currently learning C++ in school and one of our projects is to create a program to calculate a budget. When I run my program, the loop that accepts the input for item cost will take the input once and then reuse that value each time it loops back. I have already searched online for a solution and my teacher is just as confused about it as I am. It could be that there is a problem with Codeblocks but I have already tried it with a different editor. If anyone knows how I can fix it, that would be great.
#include <iostream>
#include <iomanip>
using namespace std;
int main()
{
//Declares variables
float itemCount = 0;
float taxPercent = 0;
float itemCost = 0;
bool taxable = true;
float totalTaxable = 0;
float totalNontaxable = 0;
float total = 0;
//Receive user input
cout << "How many items to you have to buy: ";
cin >> itemCount;
cout << "\nWhat is the tax percentage (do not include the % sign): ";
cin >> taxPercent;
//This code runs once for every item
while (itemCount > 0){
//Receive the remaining user input
cout << "\nWhat is the cost of the item: ";
cin >> itemCost;
cout << "\nIs the item taxable (Please use either true or false): ";
cin >> taxable;
//Adds the item cost to either the taxable or nontaxable variables
if (taxable == true){
totalTaxable += itemCost;
cout << "true";
} else{
totalNontaxable += itemCost;
cout <<"false";
}
itemCount -= 1;
}
total = (totalTaxable * (1 + (taxPercent / 100))) + totalNontaxable;
cout << "\n--------------------------------------------------\n";
cout << "You must earn $";
cout << total;
cout << " to meet this budget\n\n";
}

As said in the comment, you can't use cin on boolean. From the doc :
The standard input stream is a source of characters determined by the environment.
So here's your fixed code (which will accept Y and nothing else) :
#include <iostream>
#include <iomanip>
using namespace std;
int main()
{
//Declares variables
float itemCount = 0;
float taxPercent = 0;
float itemCost = 0;
char taxable = '';
float totalTaxable = 0;
float totalNontaxable = 0;
float total = 0;
//Receive user input
cout << "How many items to you have to buy: ";
cin >> itemCount;
cout << "\nWhat is the tax percentage (do not include the % sign): ";
cin >> taxPercent;
//This code runs once for every item
while (itemCount > 0){
//Receive the remaining user input
cout << "\nWhat is the cost of the item: ";
cin >> itemCost;
cout << "\nIs the item taxable (Please use Y for Yes): ";
cin >> taxable;
//Adds the item cost to either the taxable or nontaxable variables
if (taxable == 'Y'){
totalTaxable += itemCost;
cout << "true";
} else{
totalNontaxable += itemCost;
cout <<"false";
}
itemCount -= 1;
}
total = (totalTaxable * (1 + (taxPercent / 100))) + totalNontaxable;
cout << "\n--------------------------------------------------\n";
cout << "You must earn $";
cout << total;
cout << " to meet this budget\n\n";
}
