How to emulate C array initialization “int arr[] = { e1, e2, e3, … }” behaviour with std::array?
... by using static_assert and some TMP to detect when Tail is not implicitly convertible to T, and then using T(tail)..., but that is left as an exercise for the reader :)

What is object slicing?
... also to the copy constructor). This works because an instance of B can be converted to a const A&, which is what assignment operators and copy-constructors expect their arguments to be.
The benign case
B b;
A a = b;
Nothing bad happens there - you asked for an instance of A which is a copy ...
How can I pad a String in Java?
...
Something simple:
The value should be a string. convert it to string, if it's not. Like "" + 123 or Integer.toString(123)
// let's assume value holds the String we want to pad
String value = "123";
Substring start from the value length char index until end length of pad...
Fastest sort of fixed length 6 int array
...n's SWAP macro. Update: I switched to Paolo Bonzini's SWAP macro which gcc converts into something similar to Gunderson's, but gcc is able to better order the instructions since they aren't given as explicit assembly.
I used the same swap order as the reordered swap network given as the best perfor...
0.1 float is greater than 0.1 double. I expected it to be false [duplicate]
...
I'd say the answer depends on the rounding mode when converting the double to float. float has 24 binary bits of precision, and double has 53. In binary, 0.1 is:
0.1₁₀ = 0.0001100110011001100110011001100110011001100110011…₂

How to negate a method reference predicate
...ows how by explicitly casting the method reference to a Predicate and then converting it using the negate function. That is one way among a few other not too troublesome ways to do it.
The opposite of this:
Stream<String> s = ...;
int emptyStrings = s.filter(String::isEmpty).count();

Why must a lambda expression be cast when supplied as a plain Delegate parameter
...
A lambda expression can either be converted to a delegate type or an expression tree - but it has to know which delegate type. Just knowing the signature isn't enough. For instance, suppose I have:
public delegate void Action1();
public delegate void Action2...
