Hello ng,

Usually, I cruise through clc on the way to somewhere else, but I've 
spent so long reconstituting my c capabilities that I want to acquire a 
few more before I focus on perl. In the perl world, I'm still working 
through the material of _Intermediate Perl_, but it forces the serious 
student to get involved in the world of github, packages, and the 50% I 
haven't done yet. That can rest for the moment.

Instead I seek something that is right on the kingpin for topicality in 
clc. Here is the text file I want to substitute into:

echo 'after preprocessor your program is' >text3.txt
gcc  -E  arrow.c >>text3.txt
echo 'after compilation avec warnings, output is' >>text3.txt
gcc -Wall -Wextra -o arrow arrow.c >>text3.txt
./arrow >>text3.txt
echo 'source listing is' >>text3.txt
cat arrow.c >>text3.txt

So there's 3DBESNUB type things that a gonzaga-beating cougar will do in 
terms of general problem solving or even forensic problem-solving. Right 
at the top is that I don't know how to declare strings in c in a safe way.

Let's say that you're hard-coding a string between single quotes, for 
example:

'arrow'

, how do I declare this string to exist safely?

Do I malloc a 1000 because someone has to make an adult decision?
