I don't quite understand what K&R want me to do in Exercise 1-20 in "The
C Programming Language, 2nd Edition". Here's the description:
"Write a program detab that replaces tabs in the input with the proper
number of blanks to space to the next tab stop. Assume a fixed set of
tab stops, say every n columns. Should n be a variable or a symbolic
parameter?"
What does this mean? Do they want me to figure out the amount of spaces
a tab takes up on my system, and add them? I'm sort of confused about
this question.

You can't simply "replace all tabs with n spaces". A tab doesn't
expand to a fixed number of spaces; it expands to one or more spaces,
however many are needed to reach the next tab stop. This will vary
depending on where in the line the tab happens to appear.

In the context of LATEX, some Pythonista asked what the big
successes of Lisp were. I think there were at least three *big*
successes.
a. orbitz.com web site uses Lisp for algorithms, etc.
b. Yahoo store was originally written in Lisp.
c. Emacs
The issues with these will probably come up, so I might as well
mention them myself (which will also make this a more balanced

use static_cast to convert it into an void*. Write a function that
takes a void*, a number (indicating a number of bytes), and a value

Hello mates,
Just needed a solution on the exercises below.
Exercise 2
A classic problem in introductory programming is the grains of rice on a chess board problem.
Your program should calculate the number of rice grains on the last square of a 64 square chess board given that there is 1 grain of rice on the first square, 2 on the second square, 4 on the third square and so on.
Use a while loop to double the number of rice grains and...

I apologise if this is not the forum for my question.
I am a starter in C and I have come to a point where I can not figure
out if knowledge of assembly language is really essential for an in

Hello!
Many times I was suggested to use xrange and range instead of the
while constructs, and indeed, they are quite more elegant - but, after
calculating the overhead (and losen flexibility) when working with
range/xrange, and while loops, you get to the conclusion that it isn't
really worth using range/xrange loops.
I'd like to show some examples and I'll be glad if someone can suggest
some other fixes than while a loop :-)
