使用std：.pair吧 [英] Using std:.pair right

问题描述

我用std :: pair进行了这个小测试：


test< intt1（1）;

test< intt2（2）;

std :: pair< test< int> ;,test< int mypair = std :: make_pair（t1，t2）;


其中test是模板类我写。看起来有点麻烦

做一对比上面的程序有更好的方法吗？

解决方案

你会怎么做它更容易？ std :: pair需要知道每个

的类型，你的模板类需要知道它的模板类型。

你在哪里看到哪里可以更容易？

是：


test< intt1（1）;

test< intt2（2 ）;


auto mypair = std :: make_pair（t1，t2）;


不幸的是，你需要一个已经实现的C ++编译器这个C ++ 09

功能，以便编译此代码。

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?

What would you suggest?

How would you make it easier? std::pair needs to know the type of each of
its halves, Your template class needs to know what type it''s templated on.
Where do you see where it could be made easier?

Yes:

test<intt1(1);
test<intt2(2);

auto mypair = std::make_pair(t1, t2);

Unfortunately, you will need a C++ compiler that has implemented this C++09
feature in order for this code to compile.
