Yes, but Rant can automatically determine the dependencies between
C/C++ sources files (by extracting #include statements) and it has
some support for multiple directories (i.e. more than one Rantfile).

Actually a good example. I came up with the following solution for Rant:

% ls
c  c++ Rantfile rule.rf
% ls c
problem_1_1  template.rf
% ls c++
problem_1_1 template.rf

The main Rantfile in the root directory copies the c/template.rf Rantfile
into all c/problem_* directories and the c++/template.rf into all
c++/problem_* directories.

If you run rant in the root directory, it will compile all tests
and run them. To compile only, run rant with "build" as only argument.
During work on one of the exercises you can change into the c(++)/problem*
directory and run rant to only compile/run the current exercise.

The example is in the attachment. The only problem is, that the last
Rant release contains a bug with regards to the Rule/subdirectory
combination. If you want, I can send you my development version offlist.
