那段range-based for loops代码等价于如下: for(auto _pos=coll.begin(); _pos != coll.end(); ++_pos ) {constauto& elem = *_pos; std::cout<< elem <<std::endl; } intarray[] = {1,2,3,4,5};longsum=0;//process sum of all elementsfor(intx : array) { sum+=x; }for(auto ...
Don’t use type deduction in your range-based for loop. If we’d explicitly specified the element type asstd::string_view, then when the array was later updated tostd::string, thestd::stringelements will implicitly convert tostd::string_view, which is no problem. If the array is updated...

Range-Based For-Loop See the link: https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2009/n2930.html for the precision discussion. Quick example, note that the index of the array is the “range” for the for-loop: int roll[6] = { 1, 2, 3, 4, 5, 6 }; for (int& x ...

Having this implementation available, the range-based for loop shown earlier compiles and executes as expected. When performing argument-dependent lookup, the compiler will identify the two begin() and end() functions that we wrote (which take a reference to a dummy_array) and therefore the cod...
