Polymorphism in C++
...ndard conversion sequence will be applied to an expression if necessary to convert it to a required destination type.
These conversions allow code such as:
double a(double x) { return x + 2; }
a(3.14);
a(42);
Applying the earlier test:
To be polymorphic, [a()] must be able to operate with...
What do numbers using 0x notation mean?
...omplement- a clever way that does not require '-' sign. So, it's basically converting from binary to hex, negative or positive.

Array extension to remove object by value
... implement this using extensions.
The reason you get the error 'T' is not convertible to 'T' is that you are actually defining a new T in your method that is not related at all to the original T. If you wanted to use T in your method, you can do so without specifying it on your method.
The reason ...
C pointers : pointing to an array of fixed size
...re illegal. However, we know in practice that you can always automatically convert from char* to char const* without warning. IMO, clang is more consistent in allowing this than gcc is, though I agree with you that the spec seems to prohibit any of these automatic conversions.

Iterate through the fields of a struct in Go
...ce value then represents the
value of the field.
There is no function to convert the value of the field to a concrete type as there are,
as you may know, no generics in go. Thus, there is no function with the signature GetValue() T
with T being the type of that field (which changes of course, depe...
