I have made this little test with std::pair:
test<intt1(1);
test<intt2(2);
std::pair<test< int>,test<int mypair = std::make_pair( t1,t2);
where test is a template class I wrote. It seems a bit cumbersome to
make a pair are there any better way to do it than the above procedure?

Which - btw- I already made a day before.

That only saves keypresses if you have to create more than one
pair. With only one it requires more keypresses.

What would you suggest?
Using 'auto' in the upcoming standard?

Deducing the type of variable from its initializer expression has
already been voted into C++, so as a feature it has already been
added. Moreover, I see little reason why the poster would have to wait
until the "majority" of C++ compilers supported a

Actually, deducing the type of variable from its initializer
expression has already been voted into C++, so it's only a matter of
lobbying C++ compiler vendors to support it in their compilers.
Furthermore, I see no reason why the original poster would have to
wait until the "majority" of C++ compilers support this feature -
instead of just the C++ compiler he happens to be using.
I would point out that the "auto" keyword saves a few keystrokes only
if you already know what those keystrokes should be. But figuring out
the return type of a function call may not always be easy (e.g.
boost::bind) or even be possible (in a portable way). What type, for
example, does std::tr1::mem_f n() return:
struct A
{
int f();
};
??? mf = std::tr1::mem_f n( &A::f);
Hint: it's unspecified.

More than keystrokes, I think the point is maintainability .
Modify t1 and t2 to be test<long>, and everything works with
auto.

I haven't actually counted characters, but I believe this typedef should
save a few keystrokes even the first time around:
typedef test<intti;
ti t1(1), t2(2);
std::pair<ti, timypair=std::m ake_pair(t1, t2);

How about
std::pair<test< int>,test<int mypair(t1, t2);
? It might even be that you can write
std::pair<test< int>,test<int mypair(1, 2);
depending on your definition of test. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics | |

Hello,
I would like to ask how come the design of C++ includes
std::pair. First of all I don't think many programmers
would use it. For starters, what the first and second
members are depends on what you are using the pair
for. For instance if I am using coordinates in two
dimensional space then I like to use x and y. So
I might as well define my own struct with x and
y members in it and create a constructor so
