There are a few issues with your code above.

​

The first one which you note in the title of this post is that you have a `;` immediately after your `for` statement.

​

When you create a `for` loop, you want code to execute in that code block repeatedly. If the code you want to execute is only one line then you can put it after the `for` statement and it will be executed for each iteration of your loop. If there are more lines in your `for` loop than one, you need to enclose those lines in `{}`. A `;` indicates the end of a statement. So your first issue is that `for (int count = 0; count < 12; count++);` is treating `;` as an empty code statement. Being as that is the case, when the compiler gets to `Console.WriteLine(num1 + "   times   " + count + "equals" + (num1 * count));` it sees the `count` variable as out of scope(because the for loops scope has already finished).

​

Once you fix that though, there is one more error. `num1 * count` is treating `num1` as an integer, but you actually declared it as a string. `Convert.ToInt32(num1);` is converting that string to an integer, but then you aren't storing that value in another variable, so you can't use it below. I have corrected both of those errors in the code that follows.

​

Hope this helps.

Here is a [DotNetFiddle](https://dotnetfiddle.net/fIpEPv) demonstrating the fix.

​

            Console.Write("Enter a number for it's multiplication table: ");

    string str_num1 = (Console.ReadLine());

    int num1 = Convert.ToInt32(str_num1);

    for (int count = 0; count < 12; count++)

        Console.WriteLine(num1 + "   times   " + count + "equals" + num1 * count);

    Console.ReadLine();

    return;

*/

​

using System;

public class Program

{

    public static void Main()

    {

        Console.Write("Enter a number for it's multiplication table: ");

string str_num1 = (Console.ReadLine());

int num1 = Convert.ToInt32(str_num1);

​

for (int count = 0; count < 12; count++)

    Console.WriteLine(num1 + "   times   " + count + "equals" + num1 * count);

​

Console.ReadLine();

return;

    }

}
