if (mark < 50)

Console.WriteLine("You passed.");
}
}

Answer 1

Console.ReadLine() returns string. Convert user input to int.

int mark = Convert.ToInt32(Console.ReadLine());

Answer 2

CH Ahmad Console.ReadLine() reads the user's input.

Now when you do an input it will most likely be in String format.

Because if this, you will need to convert it to an Int, or other variable type.

Answer 3

It worked but plez explain why I need to convert even if I was typing in a whole number
