C++: combine const with template arguments

Question

The following example is working when I manualy replace T wirh char *, but why is not working as it is:

template          


        

Answer 1

Substituting T with char* gives a const pointer to char, while c is declared as a pointer to const char.

A solution would be to take pointers and integral types by value and class types by const reference. If you can, use Boost Call Traits which solves these kinds of problems for you.
