I am very aware of that, which reminds me of my early posts in this forum. Learning by "practice" related to real problem is better, like this one and the strtok() function.
You have learned one way to avoid your blind spots, but your blind spots are still there.

Am I stubborn and offending if I insist C++
As I have the same feeling like most of the beginners that sometimes C++ is easier to catch than C
Would you say you could program Perl if you just had line after line of system("echo hello world"), system("mv file1 file2"), system("echo $variable") ?

You understand integers and for-loops, and that's about all. Everything else you've just "shelled out" to an external library. Your programming comfort zone is very, very small.

If you don't recognize something, that doesn't make it "C". You've thrown out big parts of both languages along the way.

I am not able to mix C with C++ code together in one program at this moment.
Labeling everything you don't understand as "C" and therefore "out of the curriculum" is part of the problem. You've found one C++ library you like and decided that must be what the language is all about. It's not. You've overlooked something important.

I seriously think you should try and program without STL vector, string, and map for a while.

NAME

       page_util_quote - page character quoting utilities

SYNOPSIS

       package require page::util::quote  ?0.1?

       package require snit

       ::page::util::quote::unquote char

       ::page::util::quote::quote'tcl char

       ::page::util::quote::quote'tclstr char

       ::page::util::quote::quote'tclcom char

_________________________________________________________________

DESCRIPTION

       This package provides a few utility commands to convert characters into various forms.

API

       ::page::util::quote::unquote char
	      A  character,  as stored in an abstract syntax tree by a PEG processor (See the packages grammar::peg::interpreter, grammar::me, and
	      their relations), i.e. in some quoted form, is converted into the equivalent Tcl character. The character is returned as the  result
	      of the command.

       ::page::util::quote::quote'tcl char
	      This command takes a Tcl character (internal representation) and converts it into a string which is accepted by the Tcl parser, will
	      regenerate the character in question and is 7bit ASCII. The string is returned as the result of this command.

       ::page::util::quote::quote'tclstr char
	      This command takes a Tcl character (internal representation) and converts it into a string which is accepted by the Tcl  parser  and
	      will generate a human readable representation of the character in question.  The string is returned as the result of this command.

	      The  string  does not use any unprintable characters. It may use backslash-quoting. High UTF characters are quoted to avoid problems
	      with the still prevalent ascii terminals. It is assumed that the string will be used in a double-quoted environment.

       ::page::util::quote::quote'tclcom char
	      This command takes a Tcl character (internal representation) and converts it into a string which is accepted by the Tcl parser  when
	      used within a Tcl comment. The string is returned as the result of this command.

BUGS, IDEAS, FEEDBACK
       This  document,	will  undoubtedly  contain  bugs  and  other  problems.  Please report such in the category page of the Tcllib SF Trackers
       [http://sourceforge.net/tracker/?group_id=12883].  Please also report any ideas for enhancements you may have.
