Can anyone tell me what's wrong with this code? It supposed to submit value to purchaseAmount variabel 3 times. But why??

Question

#include <iostream>
using namespace std;

int main()
{
int purchaseAmount = 0;
int totalPrice;

do {
cin>>purchaseAmount;
purchaseAmount++;
}while(purchaseAmount <= 3);

totalPrice = purchaseAmount*15/100;
cout<<totalPrice<<"\n";

return 0;
}

Answer 1

Decimals will be lost if we use integers instead of floats.
Also, you need to check your do-while loop again

#include <iostream>
using namespace std;

int main()
{
int purchaseAmount = 0;
int totalPrice;
do {
cin >> totalPrice;
cout << totalPrice * 15.0/100 << endl;
purchaseAmount++;
} while (purchaseAmount < 3);

return 0;
}

Thanks, Simba!

Answer 3

#include <iostream>
using namespace std;

int main()
{
int purchaseAmount = 0;
int totalPrice;
int n=1;
//your code goes here
while (n<=3){
cin >> purchaseAmount;
totalPrice = purchaseAmount*15.0/100;
cout << totalPrice << endl;
n++;
}

return 0;
}

can anyone explain me why above code doesn't work?
