Overloaded method selection based on the parameter's real type
...n Java, dynamic method dispatch happens only for the object the method is called on, not for the parameter types of overloaded methods.
Citing the Java Language Specification:

What is the effect of encoding an image in base64?

C++ auto keyword. Why is it magic?
From all the material I used to learn C++, auto has always been a weird storage duration specifier that didn't serve any purpose. But just recently, I encountered code that used it as a type name in and of itself. Out of curiosity I tried it, and it assumes the type of whatever I happen to assig...
