C does do templates, sort-of: #define STACK_TYPE int #define STACK_MAX_SIZE 1024 #include stack_template_decl.h #include stack_template_impl.h #undef STACK_TYPE #undef STACK_MAX_SIZE (often one instances the stack_decl in a header file, and the _impl in a .c file.) I've also seen the calling convention where the template files do the #undefs. There can be some issues debugging this stuff though: gcc will give currect line numbers, but will not tell you which instance of the stack template you're in. So if a bug is only in, say, stacks of double: then this won't be immediately apparent. On the plus side, the lack of type information means that you don't get c++'s 8000-character error messages.
