Hi everyone,,
First of all, thanks to all who responded to my last question.
Here is one more question, if you all don't mind.
If I have a simple program with no classes, but one or more methods,. and I
declared a decimal variable in one of the methods. how can I reference this
variable in more then one method??
Would I define the variable as public or global? I tried both with no
result maybe I am putting it in the wrong place?
Thank Yu,
Celia

Hi Celia,
You cannot do it directly with numeric datatypes; however, converting
one to string can do the same, as:
int num = 281;
int hundredPart = int.Parse(num.ToString()
[0]
.ToString()); // I've broken the statement to make it easy to follow.
First, you convert the number into string. Then, you access the first
character (number in this case) using the character array notation (a
string is simply a sequence of characters). And lastly, you simply
convert the first character (2) back to int using the Parse method. I
have used the ToString method in the last step (to convert the
character into string) because, the int.Parse method requires an
argument of type string (and not a char type) to operate on.
