I do not know what the problem is ? Make a multiplication with entered number

I am a newbie c# user and ı am doing some practice with w3resource.com, it is the question: Write a C# Sharp program that takes a number as input and print its multiplication table: and this is my

Console.WriteLine("Enter a number : ");
int number = Convert.ToInt32(Console.ReadLine());

for (int i = 0; i < 10; i++)
{
  Console.WriteLine("{0} * {1} = {3}", number, i, number * i);

}

and it says to me that the index must be greater than 0...

An unhandled exception of type 'System.FormatException' occurred in mscorlib.dll

Solution

  • You have index {3} in the Console.WriteLine method, but you have only 3 arguments. The argument list is zero-based.

    Console.WriteLine("{0} * {1} = {3}", number, i, number * i);

    It should be

     Console.WriteLine("{0} * {1} = {2}", number, i, number * i);
