It doesn’t use an anonymous function, no. Basically the compiler converts the code into something broadly equivalent to the while loop you’ve shown here. foreach isn’t a function call – it’s built-into the language itself, just like for loops and while loops. There’s no need for it to return anything or “take” a function of … Read more
Implementations may differ, but there are some basic ideas that follow from requirements. The exception object itself is an object created in one function, destroyed in a caller thereof. Hence, it’s typically not feasible to create the object on the stack. On the other hand, many exception objects are not very big. Ergo, one can … Read more
This limit not only applies to for loops, but to all other control flow blocks as well. The limit for the number of nested control flow blocks is defined inside of code.h with a constant named CO_MAXBLOCKS: #define CO_MAXBLOCKS 20 /* Max static block nesting within a function */ This constant is used to set … Read more
An interface is intended to specify an interaction contract, not implementation details. A developer should be able to use an implementation just by looking at the interface, and not have to look inside the class which implements it. An interface does not allow you to create an instance of it, because you cannot specify constructors. … Read more
