Pointer to incomplete class type is not allowed
An “incomplete class” is one declared but not defined. E.g. as opposed to You need to #include “wielrenner.h” in dokter.ccp

You’re close. Note that you can define it inside the for loop: And if you are using C++11 then you can use a range-based for loop instead: Here auto automatically deduces the correct type. You could have written Student const& i instead.
Is there any reason I don’t see this in C++? Is it bad practice? No. It is not a bad practice, but the following approach renders your code certain flexibility. Usually, pre-C++11 the code for iterating over container elements uses iterators, something like: This is because it makes the code more flexible. All standard library containers … Read more
You need to make use of the begin and end method of the vector class, which return the iterator referring to the first and the last element respectively.

Use an Iterator and call remove():
To understand what yield does, you must understand what generators are. And before you can understand generators, you must understand iterables. Iterables When you create a list, you can read its items one by one. Reading its items one by one is called iteration: mylist is an iterable. When you use a list comprehension, you … Read more
