[Dev-C++] Question about software design

[<and...@su...>]

Dear users,

   a) I have a project file, with some .c and .h files;
   b) the main() function is worried in only find one answer,
which is the best distance (an integer) and the best tour,
an 1-D vector;
   c)to find this answer, I have to manipulate a lot of 1-D and
2-D vectors, and other simple variables in specific functions.
I´m using parameter passing functions;
   d) the size of these vectors is variable and it depends of the
user settings. So, I have to use dynamic allocation with pointers;
   e) I´m using two functions: AllocateResources() in the beginning
of the execution and FreeResources() at the end to do all the
allocations needed to run my functions. These functions are in
the main() scope. Because of this, all the vectors need to be
declared in the main().

   My problem is:
   Many of these vectors are only related to specific functions,
that is, they are only used in some functions and I have to
make reference to them in the main() scope.
   If I put the allocation inside the functions, I will make
thousands of malloc´s and free´s for the same thing!

   My question is:
   Is there any clever way to do this (make only one allocation,
run the program, free the resources at the end of the execution
and DON´T NEED TO EXIBIT ALL THESE RESOURCES-the vectors IN THE
main() SCOPE)?

Regards
Andre
