how do I declare a constant as a variable of different type

To clarify what I think you are trying to say, here is a csh example:

set name="MrBrilliant"     #read "Mr.Brilliant"
set $name=5                #delare "Mr.Brilliant" integer
echo "$MrBrilliant = 5"    #prints "5 = 5"

The answer is: you can't do this in C (you CAN simulate if you try hard
enough). What you are trying to do is take DATA (the string
"Mr.Brilliant") and declare it as a VARIABLE (int in this case). A
variable points to a memory location; data is what is stored at that
location.

This is not something you should be trying to do anyway. It implies that
somewhere in your code you are going to say something like:

    printf("Mr.Brilliant = %d", Mr.Brilliant);

If your data file changes (let's say Mr.Brilliant changes to Mr.Brillo),
this printf will now have an undeclared variable.

If you could describe what you are really trying to acomplish, we might
be able to tell you the "C" way to do handle it. I am quite sure that
the "proper" way to do it will be a lot easier than trying to simulate
what you are trying to do.
