struct X {...}; void f( X & );
X my_array[3][6][11];
for (unsigned i=0;i!=3;++i) for(unsigned j=0;j!=6;++j) for(unsigned k=0;k!=11;++k) f( my_array[i][j][k] );
Apart from all the grottiness on hardcoded sizes and loop indices, which is just for exposition, is there a nice idiom in boost to do traversals over multiple indices in this way, or perhaps multiple ranges?
In boost (and std::tr1) you've got "array" template which is static array providing stl-compliant iterators. So you can write: array<array<array<X, 11>, 6>, 3> my_array; ...and then use it, for example, in std::for_each()
