Question
Chapter 12, Problem 12.14E
Program Plan Intro
- Read the expression including whitespaces using scanf.
- Inside while loop the function evaluatePostFix perform following changes:
- Within if statement, declare a char array value.
- Next, use while loop to read each character from exp array and store it in value array.
- Use function atoi to convert the value stored in value array in integer and push it inside stack.
- Run else statement only if the expression is not blank space.
Program Description:
This program is the modified version of program provided in exercise 12.13 that can evaluate postfix expression for integers larger than 9.

(In java) Lab6C: Cha-Ching For this lab, use a do-while loop.A sentinel loop is a loop (a special while loop or a do-while loop) that continues to process data until itreaches a specific value(s) that signals that it should stop looping; this special value(s) is usuallyindicated as the condition of the while or do-while loop. A good example of a sentinel loop is the whileloop that you had to write to verify user input in Lab6B, the special values were anything in the range of1 to 1000. Another very common application for this is allowing a user to rerun a program.Please write a very simple program that mimics a bank account. The program should start the user outwith $1000. The program should print out a welcome menu once with the options present for the user.The program should allow the user to make a deposit, withdrawal, and see their current balance.Every time the user deposits or withdraws, the program should show the user their new balance; itshould also ask the user if they want…

Dynamic Programs Hoskins College offers both curriculum and continuing education courses. Write a program that dynamically tracks these courses using an array of object pointers. Every course (both curriculum and continuing education) has a course id, title, room number, and number of contact hours. A curriculum course has credit hours and tuition rate. Tuition is calculated by multiplying the course's credit hours by tuition rate. A continuing education course has a flat fee (cost). Implement a show() function in every class that displays the data in the object.
Part A: Create an inheritance-based collection of classes to represent these different courses. Include code in main to test your work by instantiating objects of the two derived classes.
Part B: Modify your program. Remove the objects you created in main to test the classes. Modify the base class so that show() becomes a virtual class.
In main, create a single array capable of holding pointers to…

Write a recursive function gcd that returns thegreatest common divisor of x and y. The gcd of x and y is defined recursively as follows: If y is equalto 0, then gcd(x, y) is x; otherwise gcd(x, y) is gcd(y, x % y), where % is the remainder operator.arrow_forward(GREATEST COMMON DIVISOR) The greatest common divisor of integers x and y is the largest integer that evenly divides into both x and y.
