问题 This question already has answers here : datetime objects format (2 answers) Closed 7 years ago . Is there a way to extract month and day using isoformats? Lets assume today's date is March 8, 2013. >>> d = datetime.date.today() >>> d.month 3 >>> d.day 8 I want: >>> d = datetime.date.today() >>> d.month 03 >>> d.day 08 I can do this by writing if statements and concatenating a leading 0 in case the day or month is a single digit but was wondering whether there was an automatic way of

问题 From the C++17 Standard Draft § 3.5.6 : The name of a function declared in block scope and the name of a variable declared by a block scope extern declaration have linkage. If there is a visible declaration of an entity with linkage having the same name and type , ignoring entities declared outside the innermost enclosing namespace scope, the block scope declaration declares that same entity and receives the linkage of the previous declaration. If there is more than one such matching entity,

问题 Can operator delete throw an exception or signal in some other way of error during memory de-allocation? In other way is it possible for operator delete to fail and what is it's default behavior in this case? Also what did ISO standard says about this? For example in Windows OS - C++ operator new and operator delete are normally implemented via functions HeapAlloc and HeapFree. The later function returns a boolean value which clearly indicates a fail is possible. Imagine how C++ operator
