1. super.smashing.great

2. b - variable names cannot begin with a numeral

3. No.
        There is no upper limit on the amount of characters in a string type

4. var1 * var2 (a)
        var3 % var4 (b)
        b / var5 (c)
        a + c
         or (var1 * var2) + ((var3 % var4) / var5)

5. int answer1, answer2, answer3, answer4;
        Console.WriteLine("Enter first of four numbers:");
        answer1 = Convert.ToInt32(Console.ReadLine());
        Console.WriteLine("Enter second of four numbers:");
        answer2 = Convert.ToInt32(Console.ReadLine());
        Console.WriteLine("Enter third of four numbers:");
        answer3 = Convert.ToInt32(Console.ReadLine());
        Console.WriteLine("Enter fourth of four numbers:");
        answer4 = Convert.ToInt32(Console.ReadLine());
        Console.WriteLine("The product of these four numbers is {0}!",
            Convert.ToString(answer1*answer2*answer3*answer4)) ;

 e. wrox.com is also not a valid variable name.

Wrox.Com is a legal variable name. "Wrox" could either be a namespace or an object that variable "Com" has been defined within. (See Exercise 01 above).

It lies on your standpoint on the title.If it refers to the concept "namespace", of course "e" is a true variable name.:)

Sorry, my English is so poor.

Hello seblake,

------------------------------------------------------
4. var1 * var2 (a)
 var4 / var5 (b)
 var3 % (b)
 (a) + (b)
 and then the final value is incremented by one.

/ operator precedes the % operator. So the computation goes like this.
------------------------------------------------------

[seblake]
No, both the / and % operators are equal in precedence. They are then evaluated as they appear left to right within a formula (except parentheses override).

The left to right evaluation does not refer to their order in the grid listing found on page 53 (Revised editition .NET 1.0). Plug in values and compute in C#. You'll see the sequence at the top of this topic is correct.

Where can I find the answers of the whole exercises?

Convert.ToString is not necessary on last line...
