2. a) Using the stack diagram, convert the following infix expression to a postfix expression. A*(B + C* (D - E) ) / F b) Referring to question 2 (a), give the value of postfix expression by using the stack concept if provided: A=4, B=3, C=6, D=10, E=2 and F=4
1 : 2 O Implementing Stack In this part, you will implement a growable stack using arrays in C++. You start with an array of size = 1. Every time the stack gets full, you copy the data to an array of double the previous size, and the new array now represents the stack. To do so, you will have to use a dynamic array (using pointers) and allocate memory using the new operator. • Write a C++ class MyStack in file MyStack.cpp that implements the above stack with follow- ing public methods. - void push(int item) : Pushes the item onto the top of the stack. - int pop() : Removes the element at the top of the stack and returns it. - int peek() : Returns the top element without removing from top of the stack. bool empty() : Returns true is the stack is empty and false otherwise. All other methods or variables in your implementation should be private.
4. a) Using the stack diagram, convert the following infix expression to a postfix expression. A + B / C * (D – E) b) Referring to question 4 (a), give the value of postfix expression by using the stack concept if provided: A=13, B=20, C=4, D=30, E=25
Q3: Write the C++ code of Stack which is performed multiple task which are given below and performed all task by using Arrays. Push values 10, 20, 5 , 50, 40, 60, 45 Pop values 45, 60, and 40 Sort all values in Stack Please create is empty and stack function for telling them stack is empty or full.NOTE: PLEASE SOLVE THE QUESTION PROPERLY AND ACCORDING TO THE REUIRED THINGS.
(c) Given the following structure definition to be implemented using a queue: struct PrintList string document; struct PrintList *next; }; Write C++ statements to perform the task below: i. Declare TWO (2) pointers commonly used in a queue and state the purpose of each pointer. ii. Insert a new node into the queue. Assume that the new node is already created and pointed by a pointer called newNode. iii. Delete a node from the queue. Assume that one pointer has been created for the delete operation purpose called delPtr.
f) Write a C++ function to insert all the elements of the vector into a stack and return the stack from the function. stack vector_to_stack(vectorv){ //write your code here }

C++ PROGRAMMINGTopic: Binary Search Trees Explain the c++ code below.: SEE ATTACHED PHOTO FOR THE PROBLEM INSTRUCTIONS It doesn't have to be long, as long as you explain what the important parts of the code do. (The code is already implemented and correct, only the explanation needed) #include "node.h" #include <iostream> using namespace std; class BTree { node* root; int size; node* create_node(int num, node* parent) { node* n = (node*) malloc( sizeof(node) ); n->element = num; n->parent = parent; n->right = NULL; n->left = NULL; return n; } public: BTree() { root = NULL; size = 0; } node* left(node* p) { return p->left; } node* right(node* p) { return p->right; } node* sibling(node* p){ if(p != root){ node* P = p->parent; if(P->left != NULL && P->right != NULL){…

1 Write a C++ code using a while statement to compute the average of all alternative nodes (1st, 3rd, 5th ...) in the given linked list where the first node is pointed to by first. NOTE: Each node has data member that stores the data and the next member that stores the address of the next node. ( means; there are any number of nodes) Use the following declaration: first Node* next; struct Node { }; int data; double total = double average; Node* temp = first; int count 0; = 0;
Write a c progrom to evaluate postfix expression like {200(200+5-2*50/4)}.No pointers allowed. Only use stack
Assume the function: void F(stack &S){ } and we send a stack S to the function F, as a result of it Select one: a. Both (copy constructor and destructor) should be called b. Destructor should be called O c. Copy constructor should be called d. Both (copy constructor and destructor) should not be called
