A friend of mine goes back and forth on what "interface" means in programming. What is the best description of an "interface"?
I\'ve seen th开发者_JAVA技巧e terms \"IB\" and \"UB\" used several times, particularly in the context of C++.I\'ve tried googling them, but apparently those two-letter combinations see a lot of use.:P
In the context of functional programming, a typical example of a side effect is \"launch the mis开发者_如何学编程siles\". Where does that expression come from historically?
In the vernacular, scope and context have a lot in common.Which is why I get confused when I read references to both, such as in the quote below from an article on closures:
How d开发者_JAVA技巧oes the following work? #include <limits> int main() { const int* const foo = &std::numeric_limits<int> ::digits;
Why this isn\'t allowed: int a = 0; int a = 0; but this is: for (int i = 0; i < 2; ++i) { int a = 0; } As far as I know code inside for loop will be executed twice whitout actually going out
What kind of language is CSS? My first inclination was to c开发者_运维百科all it a markup language... but it doesn\'t really fit the mold:
Given the base class A and the derived class B: class A { public: virtual void f() = 0; }; class B : public A {
Well, I\'m gonna be pretty straightforward here, I just have a piece of code in c++ which I\'m not sure I really understand and need some help with.
