Boost
C++ Libraries
...one of the most highly
regarded and expertly designed C++ library projects in the
world.

Alexandrescu, C++
Coding Standards
This is an older version of Boost and was released in 2023. The current version is 1.89.0.
A huge effort has been made to port the library to as many compilers as possible.
Full support for built-in arrays require that the compiler supports class template partial specialization. For non-conforming compilers there might be a chance that it works anyway thanks to workarounds in the type traits library. Visual C++ 6/7.0 has a limited support for arrays: as long as the arrays are of built-in type it should work.
Notice also that some compilers cannot do function template ordering properly.
In that case one must rely of range_iterator and a single function
definition instead of overloaded versions for const and non-const arguments.
So if one cares about old compilers, one should not pass rvalues to the functions.
For maximum portability you should follow these guidelines:
begin(),
end()
and iterator_range Range constructors
and assignment operators,
const_begin()
and const_end()
whenever your code by intention is read-only; this will also solve most
rvalue problems,
