I have some lines of code like this. can anyone explain for me why "while loop" does not stop. it is keeping shows the result more than the balance.
static void Main(string[] args) { const double balance = 303.91; const double phonePrice = 99.99; double a = 0; while (a < balance ) { a = a + phonePrice; } Console.WriteLine(a); Console.ReadLine(); } It does exactly what you have written.
The loop ends when a is bigger than balance and then you print that a variable
If you expect to stop the loop BEFORE running out of money then you need to change the loop exit condition
static void Main(string[] args) { const double balance = 303.91; const double phonePrice = 99.99; double a = 0; // You don't want to run out of money, so check if buying // another phone will bankrupt your finances.... while ((a + phonePrice) < balance ) { a = a + phonePrice; } Console.WriteLine(a); // a = 299,97 Console.ReadLine(); } you are checking the value after add so it add first then check if a greater than balanceor not so one time extra phoneprice is added with a. Make your while loop
while ((a + phonePrice) < balance) { a = a + phonePrice; }
