Question

While debugging this code I have noticed that at some specific point (info below) my variable with the name "counter" is changing from "1" to "0" for no specific reason.

There: http://screencast.com/t/1pWDfHHqc

Do you know why? I don't get it

Answer 1

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

int years,counter=0;
double ValueCar;
cout << "Value : ";
cin >> ValueCar;
cout << "Years : ";
cin >> years;

while (counter <= years)
{
counter++;
if (counter == 1)
ValueCar = ValueCar-ValueCar*30/100;
if ((counter =! 1) && (counter <=8))
ValueCar = ValueCar - ValueCar*10/100;
if (counter > 8)
ValueCar = ValueCar - ValueCar*5/100;








}

if (ValueCar < 500)
ValueCar = 500;

cout << "The value of that car is " << ValueCar;

return 0;
}

Answer 2

I would guess it has something to do with your condition, if((counter =! 1), the operator should be != and I can't say for certain how it would react with the way you have it.

Answer 3

So whats the difference between != and =! ?

Answer 4

!= is a defined operator and =! isn't.

Answer 5

It might set your counter variable to 0 because it is interpreted as counter = false

Answer 6

thank you
