Android Paint: .measureText() vs .getTextBounds()
...ounds calls nativeGetStringBounds, which are native methods implemented in C++.
So you'd continue to study Paint.cpp, which implements both.
native_measureText -> SkPaintGlue::measureText_CII
nativeGetStringBounds -> SkPaintGlue::getStringBounds
Now your study checks where these methods di...
Why can lambdas be better optimized by the compiler than plain functions?
In his book The C++ Standard Library (Second Edition) Nicolai Josuttis states that lambdas can be better optimized by the compiler than plain functions.

There is a Win32 (C++) function in shlwapi.dll that does exactly what you want: PathRelativePathTo()
I'm not aware of any way to access this from .NET other than to P/Invoke it, though.

Does Javascript pass by reference? [duplicate]
...rminology. A "reference" means something like what "pointer" means in C or C++ (well C++ has both pointers and references). However in languages like JavaScript or Java for that matter a "value" that is a particular object can only be a reference to the object. So it's not a type, really, it's a cha...
Is “argv[0] = name-of-executable” an accepted standard or just a common convention?
When passing argument to main() in a C or C++ application, will argv[0] always be the name of the executable? Or is this just a common convention and not guaranteed to be true 100% of the time?
...
Why use #ifndef CLASS_H and #define CLASS_H in .h file but not in .cpp?
...his prevents redefinition errors.
And to address your second concern:
In C++ programming as a general practice we separate development into two file types. One is with an extension of .h and we call this a "header file." They usually provide a declaration of functions, classes, structs, global v...
What is the point of a private pure virtual function?
...ic suggest a pretty common confusion. The confusion is common enough, that C++ FAQ advocated against using private virtuals, for a long time, because confusion seemed to be a bad thing.
So to get rid of the confusion first: Yes, private virtual functions can be overridden in the derived classes. Me...
Why isn't sizeof for a struct equal to the sum of sizeof of each member?
...) (like structure Z in the example above).
IMPORTANT NOTE: Both the C and C++ standards state that structure alignment is implementation-defined. Therefore each compiler may choose to align data differently, resulting in different and incompatible data layouts. For this reason, when dealing with ...
What's the point of g++ -Wreorder?
...r a warning. I thought I'd provide some historical context. The creator of C++, Bjarne Stroustrup, explains in his book The C++ programming language (3rd edition, Page 259):
The members’ constructors are called before the body of the containing class’ own constructor is executed. The constru...
