while statement#

Repeating an operation in a fast manner is a superpower of a computer. while repeats a block of operations as long as the given condition is true.

var solution = 84;
Console.WriteLine("Guess the number!");
var guess = int.Parse(Console.ReadLine());

while (solution != guess)
{
    Console.WriteLine($"Is {(solution > guess ? "greater" : "less")}. Try again.");
    guess = int.Parse(Console.ReadLine());
}

Console.WriteLine("🎉");
