What is the equivalent of the C++ Pair in Java?
...here is no Pair<L,R> in Java? What would be the equivalent of this C++ construct? I would rather avoid reimplementing my own.

Differences between C++ string == and compare()?
...rested in how the two strings relate to one another" -- although idiomatic C++ for this is to use a strict weak order (like std::less, which is also a total order in this case) rather than a three-way comparator. compare() is for operations modeled on std::qsort and std::bsearch, as opposed to those...
Iterate through a C++ Vector using a 'for' loop
I am new to the C++ language. I have been starting to use vectors, and have noticed that in all of the code I see to iterate though a vector via indices, the first parameter of the for loop is always something based on the vector. In Java I might do something like this with an ArrayList:

Is there an online name demangler for C++? [closed]
...have created such an online serivice: https://demangler.com
This is a gcc c++ symbol demangler. You just copy a stack trace, or the output of nm into a text box, and it will return the output with the names demangled.
@Update: It now demangles MSVC and Java symbols also.

Difference between 'new operator' and 'operator new'?
...
new is not an operator in C++. sizeof, for example, is an operator, but new and delete are not. new and delete are keywords and the syntactical constructs that these keywords form are called new-expression and delete-expression.

...
Pre C++11:
The function will not return the local variable, but rather a copy of it. Your compiler might however perform an optimization where no actual copy action is made.
See this question & answer for further details.

Exotic architectures the standards committees care about
I know that the C and C++ standards leave many aspects of the language implementation-defined just because if there is an architecture with other characteristics, it would be very difficult or impossible to write a standard conforming compiler for it.
