Error on code

Question

Hello! I am fairly new to coding and I am currently learning c#. I was practicing what I have learned, but it says that this is wrong. This is the output error message:
Syntax error, ‘(‘ expected
) expected
‘else cannot start a statement
Syntax error, ‘(‘ expected
Invalid expression term ‘else’
) expected
; expected
; expected

This is my code.

What do I need to fix?

Answer 1

Hello Coder09

If statements should be in this form:

if(condition){

}

You are asking for a string, so you should compare the answer with "19"

if(answer == "19"){

...

And you are missing ; after Console.WriteLine("Wrong")

Here is the correct code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace SoloLearn
{
class Program
{
static void Main(string[] args)
{
string answer;

Console.WriteLine("What is 9+10");

answer = Console.ReadLine();

if(answer == "19")
{
Console.WriteLine("Correct!");
}
else
{
Console.WriteLine("Wrong!");
}
}
}
}

Answer 2

// or

if (Convert.ToInt32(answer) == 19)
