Program Plan Intro
Quick sort template
Program Plan:
Main.cpp
- Include the required header files.
- Declare the necessary function prototype and constants.
- Define the main () function.
- Declare the necessary variables.
- Get the required input from the user.
- Call the method “quickSort()” to perform the sort operation for the given elements.
- The sorted values are being displayed to the user using a loop.
Quicksort.h
- Define the template function necessary.
- Define the method definitions that compares and performs sort operation for the contents of the array using quick sort.
- Define the method “quickSort()”,
- Declare the necessary variables.
- Condition statement that compares the values present at the beginning and at the end.
- Call the method “partition()” to partition the list.
- Call the method “quicksort()” to sort the first and second sub lists.
- Define the method “partition()”,
- Declare the necessary variables.
- Calculate the mid value of the list.
- Call the function to perform necessary swap using “swapVars()”.

- You will write a program that allows the user to keep track of college locations and details about each location. To begin you will create a College python class that keeps track of the csollege's unique id number, name, address, phone number, maximum students, and average tuition cost. Once you have built the College class, you will write a program that stores College objects in a dictionary while using the College's unique id number as the key. The program should display a menu in this order that lets the user: 1) Add a new College 2) Look up a College 4) Delete an existing College 5) Change an existing College's name, address, phone number, maximum guests, and average tuition cost. 6) Exit the programarrow_forwardShow all the workarrow_forwardConstruct a frequency polygon density estimate for the sample in Question 1, using bin width determined by Sturges’ Rule.arrow_forward
