Hi, I am fairly new to C++, and I am getting an infinite loop in this code, and I have no idea why. Basically, my program is to tell me in how many years I can buy the car of my dreams, which costs a certain amount with a certain depreciation rate, with the money I have to invest at a certain interest rate.

Any help with this would be greatly appreciated!!!

#include <iostream>
using namespace std;
int main()
{


float Invest;
float InterestRate;
float CarPrice;
float Depreciation;
float InvestGrow;
float CarDecrease;
int Year = 0;


cout << "Please enter the amount of money you have to invest (in dollars):" << endl;
cin >> Invest;

cout << "Please enter the interest rate earned on the invested amount (in percent):" << endl;
cin >> InterestRate;

cout << "Please enter the current value of your dream car (in dollars): " << endl;
cin >> CarPrice;

cout << "Please enter the depreciation rate for the car (in percent):" << endl;
cin >> Depreciation;



do
{
InvestGrow = (Invest + (Invest * (InterestRate/100)));
CarDecrease = (CarPrice - (CarPrice *(Depreciation/100)));
Year = Year + 1;
cout << "At the end of year " << Year << " you have $" << InvestGrow << "and the car now costs $" << CarDecrease << "." << endl;


}
while (InvestGrow <= CarDecrease);

//Text output



return 0;

InvestGrow never grows. Instead of

InvestGrow = (Invest + (Invest * (InterestRate/100)));

changing it to this

InvestGrow = InvestGrow + (InvestGrow*(InterestRate/100))

But you also need to initialize InvestGrow with the value of your initial investment before the do...while loop.

I didn't try it but it may help.

Thank you so much, I've got it to work, finally :)
