Can one make multiple Wubi installs, and if not, is it possible to change from one Wubi installation to another (for example by exchanging the root.disk file under Windows with one of another Wubi...

I seem to be disallowed to post or create new thread in some forums. Why?

When I used the little shell in Grub2, this specific command did not work.
I got an error like that the binary format of /vmlinuz was invalid or something.

Thanks.

But I already solved it in another way, uninstall WUbi and re-install it, after I backed up disk.root. Is there any way I can acess disk.root to retrieve my files?
Can I recopy that old...

I experienced the same kind of problem as described here.

However, I have two seperate menus: one for choosing between Windows or Ubuntu, and one for the Ubuntu installation.
That second menu is...

I am using Ubuntu from a Wubi installation under Windows XP.
The ubuntu installation is on the second partition of my laptop drive, installed on d:\ubuntu\disks\root.disk.

Already found the solution: for some reason the first left/right truncatable prime was not generated by this algorithm, so all 11 numbers are there:
23
37
53
73
313
317
373
797
3137

Project Euler has some very challenging mathematical problems which can be solved using your programming skills.
Thus far I managed to solve 23 (out of a total of 196 problems) of them.

SQL is pretty much worth considering - in combination with understanding how an RDBMS works - since it is used pretty much in large-scale projects everywhere.
And most RDBMS'es support some sort of...

Of course that works, but only at runtime. I was aiming at assembling strings of (static/constant) data at compile time using the preprocessor....

The "meaning" of a "program" is defined by it's grammatical (and lexical) rules, which map a textual representation of the program onto the instruction set and other characteristics of the target...

Writing a program like that is not done anymore nowadays.
You probably have heard about this about the 1st generation computers in the 40ies/50ies, when there wasn't even an assembler, and you had...

Painfull!!

Where are the good tools when you need them???

I just accidentally deleted some source files when reconfiguring my sources.
At that precise moment I could need some unremove...

Thx for the fix of '*'.
By the language spec it should compile Ok, but why doesn't Example 3 which -after preprocessing - results in the same source??

Good loop construct would in this case be:



do
#prompt user for input
prompt Message
#get input from user, returning flags:good-input and bail-out

For a programming project in C I want to be able to concatenate two strings, but not sure if the gcc preprocessor is accepting the syntax.
Basically the idea is this (Example 1):

If I am not mistaken (not been coding Cobol in years) the PIC 9(7) format is a decimal format, not alphanum. Need to supply PIC X(20) or so (7 chars is a bit short).

Small mistake: you used
&name for the string to print, but that is incorrect, as it takes the adress-of the string array, not the array itself. So it needs to read:


#include <stdio.h>
