Simple if you know your basic math, just take ceil(log10(n+1)).

In the general case, if you have two classes that depend on each other and one dependency is only on references or pointers, you can forward declare one of them before declaring the other, and define the methods after both are declared: Code: struct X; struct Y { Y( X & other ); // arguments (passed by pointer/reference/value are allowed) X f(); // return values are ...

I have seen a similar ranking of languages from another source not too long ago... so I would imagine it is definitely in the ballpark...

another way to think about it could be: Code: a = [1, 2, 3, 4] b = [] b.extend(a) a.append(5) print b b would print [1, 2, 3, 4]

A list will probably do the job PHP Code: >>> counter = 1 >>>for k in range ( 1 , 11 ): number [ counter ]= k counter = counter + 1

nothing?

java.sh Code: #!/bin/bash echo -e "//Java stuff//More java stuff" > $1 gedit $1 ./java.sh <filename> What is happening here is you are using echo to create and insert text into the file (-e allows to be translated into actual newlines), and gedit to open that file.

Thanks, I punched your code in and it worked fine. Must've been the line feeds. BTW how did you get an error message? At the moment I'm just guessing what the errors are! A dubber of some sorts would be nice.
