This is really frustrating, I’ve tried multiple variations of my class and constructor, sifted through pages of google results and other questions on this site but I can’t figure it out. I believe the error is something simple that I’m overlooking. Error code: student.h student.cpp main.cpp Just as a note, my professor said adding #include … Read more
The first constructor in the header should not end with a semicolon. #include <string> is missing in the header. string is not qualified with std:: in the .cpp file. Those are all simple syntax errors. More importantly: you are not using references, when you should. Also the way you use the ifstream is broken. I suggest learning C++ before trying to use it. … Read more
Move the to a cpp file. If you have it in a header, then every .cpp that includes it will have a copy and you will get the duplicate symbol error during the link.
I know that Python does not support method overloading, but I’ve run into a problem that I can’t seem to solve in a nice Pythonic way. I am making a game where a character needs to shoot a variety of bullets, but how do I write different functions for creating these bullets? For example suppose … Read more
VisitedSet is a template, not a class, so you can’t use VisitedSet in a nested name specifier such as VisitedSet::getSize(). Just as you specified the declaration of class VisitedSet<T> for all class T, you must specify the definition of VisitedSet<T>::getSize() for all class T: The name of a template can, however, be used as though it were a class within a template definition: In this case, Example is short … Read more
I am having a problem with calling a method that is in a different class. This main method is in a class on its own called lab14, and the heapSort() method is in a different class called HeapSort. Both of these classes are in the default package. I am getting the error “The method heapSort(Vector) … Read more
If all of your classes are in the same package, you shouldn’t need to import them. Simply instantiate the object like so: CustomObject myObject = new CustomObject();
You forgot the return types in your member function definitions: and so on.
Using the generified version of class Class allows you, among other things, to write things like and then you can be sure that the Class object you receive extends Collection, and an instance of this class will be (at least) a Collection.
it should be next = newNext; instead of next = newNext->next;
