Convert Domical to Binary Numbers

Let's examine the table below that displays what we are going to implement.

Decimal Binary
1 0
2 10
3 11
4 100
5 101
6 110
7 111
8 1000
9 1001
10 1010

Let’s start.

Console.WriteLine("Enter a Decimal Number: ");
int number = Convert.ToInt32(Console.ReadLine());
string result = string.Empty;
for (int i = 0; number > 0; i++)
{
    result = number % 2 + result;
    number = number / 2;  // Corrected the syntax here
}
Console.WriteLine($"Binary Number: {result}");
Console.ReadLine();

Output

Decimal number

Let's try another number.
