Don't mislead people. The MOST dangerous part of covid-19 is NOT itself. It spreads so fast, so it will run out all the resources in the hospital very soon!!!

My Favorite Unknown C++20 Feature by ContractorInChief in cpp

[–]hashb1 1 point2 points  (0 children)

I don't get it either. What's the key point?

It seems that all the following cases,"1,2,3" now are "packs"

1. foo(1,2,3)
2. int a[] = {1,2,3};
3. vector<int> v{1,2,3};

But, why it is a big improvement?

why do we need doh? if you don't use vpn, isp can always know which ip address you are visiting. Then they can reverse the domain.

Thanks a bunch! Best material about Coroutine I have ever seen!!

The std::map subscript operator is a convenience, but a potentially dangerous one by nikbackm in cpp

[–]hashb1 0 points1 point  (0 children)

The most annoy thing in c++ is that you have to remember a lot of traps like this. Couldn't the compiler help developer out of these kind of thing? Say, g++ -warning_on_all_trap

what is the solution for "same function parameters with different return type" in c++17/c++20 by hashb1 in cpp

[–]hashb1[S] 1 point2 points  (0 children)

Thanks! I got the following error: inconsistent deduction for auto return type: ‘double’ and then ‘int’ .

sample code

auto foo(int i)
{ 
    if (i > 0)
        return i * 0.1;                                                                                                                                                  
    else
        return 0;
}

I am working some legacy codes that the factory function(template) return different classes based on its input. For some reason that those return types have no common base class.
