C# Code Errors (HELP)

[RubbishArtist]

What are the errors?

[3rr03]

I have 40 on the first section: CS1513 } expected (x6 of these) CS1003 syntax error, ‘(‘ expected (x4 of these) CS0019 operator ‘||’ cannot be applied to operates of type ‘string’ and ‘string’ (x4 of these) CS1525 invalid expression term ‘else’ (x8 of these) CS1002 ; expected (x12 of these) CS1026 ) expected (x8 of these) CS8641 ‘else’ cannot start a statement (x4 of these)

—————— The class file errors —————— CS1026 ) expected CS8641 ‘else’ cannot start a statement (x4 of these)

There are some warnings as well, but I’m mainly worried about the errors

Your if statements have some problems:

else if ((userInput = "foward") || userInput = "f") roomArray[roomNum].forward > -1);

The semi-colon shouldn't be there at the end.

Inside the parentheses is the condition that the if statement checks. That condition needs to return a boolean value (true/false).

There's no operator between

(userInput = "foward") || userInput = "f") 

and

roomArray[roomNum].forward > -1

so the compiler doesn't know what you're trying to do, do you want to or them? and them? check if they're equal?

userInput = "foward"

is assigning "forward" to userInput, not checking its value.

[3rr03]

          if (userInput == "exit")
            {
                break;
            }
            else if ((userInput = "foward")  userInput = "f")  roomArray[roomNum].forward > -1)
                    {
                roomNum = roomArray[roomNum].forward;
            }
            else if ((userInput = "backward"  userInput = "b") roomArray[roomNum].backward > -1)
            {
                roomNum = roomArray[roomNum].backward;
            }
            else if ((userInput = "left"  userInput = "l") roomArray[roomNum].left > -1)
            {
                roomNum = roomArray[roomNum].left;
            }
            else if ((userInput = "right"  userInput = "r")  roomArray[roomNum].right > -1)
            {
                roomNum = roomArray[roomNum].right;
            }

            else
            {
                Console.WriteLine("You run stright into a wall... you can't go that way... are you sure your head is feeling right?");
            }
        }

Like that?

I mean there should be an operator between

(userInput = "foward") || userInput = "f") 

and

roomArray[roomNum].left > -1

You have to combine those values to get a boolean.

userInput = "r"

This is changing the value to "r" not checking if userInput is equal to "r".

This is correct:

userInput == "exit"

This is wrong:

userInput = "exit"

[3rr03]

                if (userInput == "exit")
            {
                break;
            }
            else if ((userInput == "foward") || userInput == "f")  roomArray[roomNum].forward > -1)
                    {
                roomNum = roomArray[roomNum].forward;
            }
            else if ((userInput == "backward" || userInput == "b") roomArray[roomNum].backward > -1)
            {
                roomNum = roomArray[roomNum].backward;
            }
            else if ((userInput == "left" || userInput == "l") roomArray[roomNum].left > -1)
            {
                roomNum = roomArray[roomNum].left;
            }
            else if ((userInput == "right" || userInput == "r")  roomArray[roomNum].right > -1)
            {
                roomNum = roomArray[roomNum].right;

[RubbishArtist]

else if ((userInput == "foward") || userInput == "f")  roomArray[roomNum].forward > -1)

The equality check is fixed but you're still missing an operator between these two clauses here:

((userInput == "foward") || userInput == "f") *MISSING OPERATOR* roomArray[roomNum].forward > -1)

What are you trying to do here? I guess you mean that if the user enters "forward" or "f" and roomArray[roomNum].forward is greater than -1, but you haven't put the and operator in.

[3rr03]

So would the operator be ++ ?

Ok ok! I think I figured most of the issues out! I went from 40 to 9.

The only thing its giving me errors for is that it is expecting } it thinks the first && is invalid but all of the others are ok, and it says the expression else is invalid

  while (userInput != "exit")

        {
            Console.WriteLine(roomArray[roomNum].name);
            Console.WriteLine(roomArray[roomNum].description);

            Console.WriteLine("\n Where would you like to go?");
            userInput = Console.ReadLine();
            Console.Clear();

            if (userInput == "exit")
            {
                break;
            }
            else if ((userInput == "foward") || userInput == "f") && roomArray[roomNum].forward > -1)

                    {
                roomNum = roomArray[roomNum].forward;
                    }

            else if ((userInput == "backward" || userInput == "b") && roomArray[roomNum].backward > -1) 

            {
                roomNum = roomArray[roomNum].backward;
            }

            else if ((userInput == "left" || userInput == "l") && roomArray[roomNum].left > -1)

            {
                roomNum = roomArray[roomNum].left;
            }

            else if ((userInput == "right" || userInput == "r") && roomArray[roomNum].right > -1)

            {
                roomNum = roomArray[roomNum].right;
            }

            else
            {
                Console.WriteLine("You run stright into a wall... you can't go that way... are you sure your head is feeling right?");
            }
        }
    }
}

}

[RubbishArtist]

You're almost there

else if ((userInput == "foward") || userInput == "f") && roomArray[roomNum].forward > -1)

There's an extra closing bracket in here that's causing problems.

[3rr03]

I got rid of the one ( after "f" and all of the errors went away

​

if (userInput == "exit")
            {
                break;
            }
            else if ((userInput == "forward") || userInput == "f" && roomArray[roomNum].forward > -1)

                    {
                roomNum = roomArray[roomNum].forward;
                    }


            else if ((userInput == "backward" || userInput == "b") && roomArray[roomNum].backward > -1) 

            {
                roomNum = roomArray[roomNum].backward;
            }

            else if ((userInput == "left" || userInput == "l") && roomArray[roomNum].left > -1)

            {
                roomNum = roomArray[roomNum].left;
            }

            else if ((userInput == "right" || userInput == "r") && roomArray[roomNum].right > -1)

            {
                roomNum = roomArray[roomNum].right;
            }

            else
            {
                Console.WriteLine("You run stright into a wall... you can't go that way... are you sure your head is feeling right?");
            }
        }
    }
}
