When should I use C++14 automatic return type deduction?

wish of those help C++11 raises similar questions: when to use return type deduction in lambdas, and when to use auto variables.
The traditional answer to the question in C and C++03 has been "across statement boundaries we make types explicit, within expressions they are usually implicit but we can make them explicit with casts". C++11 and C++1y introduce type deduction tools so that you can leave out the type in new places.

wish helps you I am trying to understand the following code that I saw today. I already tried to find a related question, but since I have no idea what this feature of C++ is called it is hard to find related posts. A hint on the correct search term might already help me. , Here's a simplified demonstration:
code :
struct X { X(int); };

void foo(X );
template <typename T> void bar(T );

foo({0}); // ok
bar({0}); // error
bar<X>({0}); // ok
bar(X{0});   // ok
make_unique<B>(A{5})
make_unique<B>(B({5}))
unique_ptr<B>(new B({5}))
make_unique<B, A>({5});

like below fixes the issue I have some code in a template like so: , You could wrap it in an immediately invoked lambda expression
code :
auto stat = [&] {
    if constexpr ( std::is_same_v<T, CompletedGeneration> ) {
        return stats->getGenerationStats();
    } else if constexpr ( std::is_same_v<T, CompletedReset> ) {
        return stats->getResetStats();
    } else if constexpr ( std::is_same_v<T, CompletedRun> ) {
        return stats->getRunStats();
    }
}();

Does that help Random thoughts:
You could possibly get at the type of the proxied object by using decltype(*func()), or however the proxied object is accessed. There are no modifiers to auto other than the usual const, &, etc.

I think the issue was by ths following , is it possible to do something like: , You can use an auto template parameter in C++17:
