c# switch problem

Question

I\'m new to programming and having a problem with the following code:

    private string alphaCoords(Int32 x)
    {
        char alphaChar;

        switch (         


        

Answer 1

The compiler is complaining because alphaChar is possibly undefined -- if it is not one of the values in your switch then it will not have been defined. You can do one of the following things:

• Set an initial value of char which will be carried through if none of the switch conditions is true.
• Add a "default" clause to your switch statement.
