Disadvantages of templates:

1. Many compilers historically have very poor support for
templates, so the use of templates can make code somewhat
less portable.
2. Almost all compilers produce confusing, unhelpful error
messages when errors are detected in template code. This
can make templates difficult to develop.
3. Each use of a template may cause the compiler to
generate extra code (an instantiation of the template), so
the indiscriminate use of templates can lead to code bloat,
resulting in excessively large executables.

Answer / ranjit

one disadvantage is non-standards conforming compilers.
templates can also sometimes make maintaining code harder
and less clear, although the exact opposite can be said as
well.
Templates aren't *inherently* code bloating.
