University of Missouri Kansas City Iterator and A Const Iterator Discussion Hello, I need someone that can complete this assignment by 11;30 PM (CT, US). The assignment is detailed explained in the document.Thank you. 1. (Weight: 10%) Explain why we need both an iterator and a const_iterator
2. (Weight: 10%) Indicate whether you should use an iterator or a const_iterator as a
parameter in new functions for the list class that would perform each of these
operations.
a. Insert a new element after the current iterator position.
b. Replace the data stored in the currently selected item.
c. Retrieve the data stored in the currently selected item.
d. Insert a new element before the currently selected item.
3. (Weight: 10%) Programming: Write a function that reads a line and reverses the words in
the line (not the characters) using a stack. For example, given the following input:
The quick brown fox jumps over the lazy dog.
You should get the following output:
dog. lazy the over jumps fox brown quick The
4. (Weight: 10%) Trace the evaluation of the following expression using
class Postfix_Evaluator. Show the operand stack each time it is modified (Use
Postfix_Evaluator on Blackboard).
10 2 * 5 / 6 2 5 * + –
•
Here is an example of tracing what happens when the first operand is parsed:
Expression
Action
Stack
10 2 * 5 / 6 2 5 * + – Push 10 ?10?
????
?
•
Note: Take care – when you copy expressions (like the one above and the ones below)
below)
into visual studio. Make sure the minus sign ((-) is copied as a minus sign not a dash. If it
is copied as a dash, change it into a minus sign so that Visual Studio doesn’t throw an
error.
5. (Weight: 20%) Trace the conversion of the following expressions to postfix using the
Infix_To_Postfix class. Show the operator stack each time it is modified. (You can find
the class on Blackboard)
y – 7 * 35 + 4 / 6 – 10
( x + 15 ) * ( 3 * ( 4 – ( 5 + 7 / 2 ) ) )
6. (Weight: 10%) How would you modify class Infix_To_Postfix to handle the
exponentiation operator, indicated by the symbol ^. The first operand is raised to the
power indicated by the second operand. Assume that a sequence of ^ operators will not
occur and that precedence(‘^’) is greater than precedence(‘*’).
7. (Weight:15%) Write an algorithm to display all the elements in a queue using just
the queue operations. How would your algorithm change the queue?
8. (Weight:15%) Programming: Write a new queue function called move_to_rear that
moves the element currently at the front of the queue to the rear of the queue. The
element that was second in line will be the new front element. Do this using
functions push, front, and pop.
