Chapter 19, Problem 28RQE
Explanation of Solution
Static Stack and Queue:
- A static stack and queue has fixed size.
- The usual implementation is in the form of an array.
- The starting size of the stack and queue should be specified.
- The elements cannot be added if the specified size is full.
Operations performed on static stack:
A static stack can perform two operations...

(Postfix Evaluation) Write a program that evaluates a valid postfix expression such as
6 2 + 5 * 8 4 / -The program should read a postfix expression consisting of digits and operators into a string. Using modified versions of the stack functions implemented earlier in this chapter, the program should scan the expression and evaluate it. The algorithm is as follows:
While you have not reached the end of the string, read the expression from left to right.
If the current character is a digit,
Push its integer value onto the stack (the integer value of a digit character is its value in the computer’s character set minus the value of '0' in the computer’s character set).
Otherwise, if the current character is an operator,
Pop the two top elements of the stack into variables x and y.
Calculate y operator x.
Push the result of the calculation onto the stack.
When you reach the end of the string, pop the top value of the stack. This is the result of the postfix expression.

- C++ The List class represents a linked list of dynamically allocated elements. The list has only one member variable head which is a pointer that leads to the first element. See the following code for the destructor to List. ~ List () { for (int i = 0; i <size (); i ++) { pop_back (); } } What problems does the destructor have? Select one or more options: 1. There are no parameters for the destructor. 2. The return value from pop_back (if any) is nerver handled. 3. The destructor will create a stack overflow. 4. The destructor will create dangling pointers. 5.The destructor will create memory leaks. 6.The destructor will create undefined behavior (equivalent to zero pointer exception). 7.The condition must be: i <size () - 1 8. There is at least one problem with the destructor, but none of the above.arrow_forwardupperStackRec(CharStack s) – This method takes a character stack and converts all lower case letters to upper case ones.

- Programming in C: Challenge 1: Create and Print a Doubly Linked List In class, I briefly mentioned how to create a doubly linked list (a linked list with two directions: forward and backwards). This task challenges you to create a doubly linked list of 5 nodes. If your nodes were called n1, n2, n3, n4 and n5 (which they shouldn’t, please give them original names), your list should be linked as follows: We discussed what "start" and "end" should be. Then, also in main, you will have to print the list forwards by taking advantage of the arrows pointing to the right. You will also have to print it backwards taking advantage of the arrows pointing to the left. Again, everything must be done in main. Hint: look at the way in which I printed the singly linked list in class. In other words, if your nodes had the values: n1=1, n2=2, n3=3, n4=4 and n5=5; your program should print:1 3 5 2 4 (forwards) and 4 2 5 3 1 (backwards).
