Replied To a Post in Reversing an answer
Because you're essentially looking at the least significant bit first, you're printing them first, and as a result, the number is being printed backwards. A couple of notes here. The … -
Replied To a Post in multiple definition of .. and undefined reference of.. c++
To be perfectly honest, the main way I would improve that code is to completely get rid of the `foo` class. It only has one actually peice of data in … -
Replied To a Post in multiple definition of .. and undefined reference of.. c++
First code: You're calling `mainPage()` as if it belongs to the global scope. The way you've written your code, though, it actually belongs to your class `foo`. My best bet … -

Replied To a Post in sieve's algorithm for finding prime numbers between given range
You're erasing elements by position rather than by value. Once you start erasing values like that, you can't expect `v[number]` to be equal to `number` anymore. A better solution to … -

You would make the fuction virtual, which allows you to override the behavior of a function when defining the child class. It should be as simple as changing `void set_dimensions()` … -

Replied To a Post in for_each output through global function access
Because that's not the syntax for range-based `for` loop. I can't imagine it would work with `for_each` either because you're iterating through `string`s, and your `add()` functions operates on and … -
Replied To a Post in for_each output through global function access
Is there any particular reason you're using `for_each` when you already have C++11's range based `for` loops available? Is it part of an assignment that your `add()` function has to … -

Replied To a Post in help with iterator & array
Another way to print the values pointed to by the vector is to use C++11's new range-based `for` loops (if you have an up-to-date compiler). This way, you don't even … -

Replied To a Post in about pointers and dot operator
What exactly is Vvariant supposed to be? It's impossible to get the value of a `void*` (without typecasting it first), and it's dangerous to dereference a pointer that is `NULL`.
