getPosition is non-const in the interface class, but const in your derived class. These are two different functions and cause your problem. Adding the override keyword in the implementation class (if your compiler supports it) will flag this sort of problem. 0 solved C++ cannot instantiate abstract class
It helps to read the documentation, that would have told you queue<int> q; … int cur = q.front(); q.pop(); solved Assign first item of queue to int [closed]
As you can tell from some of the comments, multithreaded code is serious business. It’s best to follow a proven pattern, e.g. producer-consumer, or at least use an established synchronization primitive like a monitor or semaphore. Because I might be wrong. It is easy to go over code that you came up with yourself and … Read more
in for (int i = 0; i <= vector_data.size(); i++) { Instr = vector_date.front(); vector_data.pop(); hpp_DE.push(Instr); } the size of vector_data changes because of the pop and at the same time you increment i to compare it to the (modified) size, this is wrong if you want to copy all the elements. You use struct … Read more
All you have to do is just adding a single line after the do-while loop as follows: do { cout << temp->data << “->”; temp = temp->link; } while (temp != front); cout<< front->data << “->”; assuming front is the head of your linked-list. Now I’ve a question for you, what you gonna do if … Read more
I did not understand how the output you showed has one of the numbers multiplied by 100 in each element of String array. Based on my understanding of your question here is a solution. import java.util.Arrays; import java.util.Collections; import java.util.LinkedList; import java.util.stream.Collectors; import java.util.stream.IntStream; public class Shifts { public static void main(String[] args) { LinkedList<Integer> … Read more
That ‘terminated’ you have been seeing lately is the expected behavior when your program finishes. Put some System.outs or asserts to verify that your code runs (here it runs, with some awful cast warnings, but runs) final Queue12<T> ringBuffer = new QueueImpl12<T>(); T o = (T) new String(“this”); ringBuffer.enqueue(o); //add element to the back System.out.println(ringBuffer.peek());//this … Read more
Deque: This would be a decent choice, since you can add/remove from both the front/end of the line in O(1) time, and the number of patients can be kept track of with an integer variable, so getting the size of the line would be O(1). You can also ensure a max capacity of N by … Read more
Yes – poll removes the first item in the list and returns it. This will then be evaluated in your if statement. On an unrelated note, it is worth mentioning that the size of edges will obviously change on every loop since polling edges reduces the element count by one. However, your for loop evaluates … Read more
