- FOLLOW QUESTION AND MATCH OUTPUT AS IT IS ------------------------------------- Write a C++ program to perform the Queue operation. Note:Use the following class template for Queue creation. template <class T>class Queue{ private: int front,rear; T *queue; int maxsize;}; Define the following function in the class Queue class Method name Description int isFull() The method is used to check whether the queue is full or not. void insert(T) The method is used to display the rear element in the queue (if the queue is stored with the element(s)). void deletion() The method is used to delete the front element from the queue. void atFront() The method is used to display the front element in the queue (if the queue is stored with the element(s)). void atRear() The method is used to add data to the rear end of the queue. void display() The method is used to display all the data in the queue. int isEmpty() The method is used to check whether the…When constructing a priority queue, what is the bare minimum number of queues that should be used?Q. Difference between Stack and Queue Data Structures. Write down key differences. Write some code snippets. Draw images with some examples. Show differences for operations like push/pop, add/remove, etc.
- 20 T OR F An application programmer can prevent accessing an empty queue by using the isEmpty method in an if-statement to prevent such access.17 T OR F The QueueInterface interface represents a contract between the implementer of a Queue ADT and the programmer who uses the ADT.Language: C++ Note: Write both parts separately. Part a: Complete the above Priority Queue class. Write a driver to test it. Part b: Modify the above class to handle ‘N’ different priority levels
- Implement a Queue using a vector or the STD ::queue:: class Note the difference in what it takes to implement using a char[] array vs a vector or the STD ::queue:: class The user will input a string and the program will return the string with each letter in the string duplicated. Displaying correct Queue implementation. Utilize the conventional methods as needed. Sample Execution Please input String: happy Program will produce the output string. Only use the enqueue(), dequeue(), empty(), etc hhaappyyUsing C++ . Create a queue using a linked list as your container and use a class. The system must have enqueue and dequeue operations and functions such as, isfull() and isempty(). Make sure it has an input and 10 data will be accepted.Please convert the code from C Language #include <bits/stdc++.h> using namespace std; struct Queue { stack<int> s1, s2; // stl used // Enqueue an item to the queue void enQueue(int x) { // Push item into the first stack s1.push(x); } // Dequeue an item from the queue int deQueue() { // if both stacks are empty if (s1.empty() && s2.empty()){ cout << "Queue is empty"; exit(0); } // if s2 is empty, move elements from s1 if (s2.empty()) { while (!s1.empty()) { s2.push(s1.top()); // using stl operation top() s1.pop(); } } // return the top item from s2 int x = s2.top(); s2.pop(); return x; } }; // main function int main() { Queue q; int x,count=0; cout<<"press 0 to stop push operaton, else enqueue integers"<<endl; cin>>x; while(x){ q.enQueue(x); count++; cin>>x; } cout<<"dequeueing...."<<endl; while(count){ cout<<q.deQueue()<<endl; count--; } cout<<"execution successful"<<endl; return 0; }…
