5. A new exercise program is proposed to increase the V02 max (a measure of fitness in mL/kg/min) of men with sedentary lifestyles. The researchers randomly recruited 25 such men from their local health care centre. They measured the V02 max of each individual at the start of the study (pre) and then again after 6 months of participating in the exercise program (post). The data are available in the file VO2max.csv.

n this lab, you use what you have learned about searching an array to find an exact match to complete a partially prewritten C++ program. The program uses an array that contains valid names for 10 cities in Michigan. You ask the user to enter a city name; your program then searches the array for that city name. If it is not found, the program should print a message that informs the user the city name is not found in the list of valid cities in Michigan.
The file provided for this lab includes the input statements and the necessary variable declarations. You need to use a loop to examine all the items in the array and test for a match. You also need to set a flag if there is a match and then test the flag variable to determine if you should print the the Not a city in Michigan. message. Comments in the code tell you where to write your statements. You can use the previous Mail Order program as a guide.
Instructions
// MichiganCities.cpp - This program prints a message for
invalid cities in Michigan.
// Input: Interactive
// Output: Error message or nothing
#include <iostream>
#include <string>
using namespace std;
int main()
{
// Declare variables
string inCity; // name of city to look up in
array
const int NUM_CITIES = 10;
// Initialized array of cities
string citiesInMichigan[] = {"Acme", "Albion", "Detroit",
"Watervliet", "Coloma", "Saginaw", "Richland", "Glenn", "Midland",
"Brooklyn"};
bool foundIt = false; // Flag variable
int x; // Loop control variable
// Get user input
cout << "Enter name of city: ";
cin >> inCity;
// Write your loop here
if inCity = citiesInMichigan then "A city in Michigan" if else then
"Not a city in Michigan";
// Write your test statement here to see if there is
// a match. Set the flag to true if city is found.
// Test to see if city was not found to determine if
// "Not a city in Michigan" message should be printed.
return 0;
} // End of main()

Prepare and record a 8-10 minute Kaltura presentation with a Power Point that summarizes your reflection on the learning experience within the MBA degree program. This is not reflection of this course, but rather an reflection of the comprehensive MBA program and your assessment of your achievement.
It should reflect your candid assessment of the level of achievement of degree’s overall Learning Outcomes listed below:
For each of the five learning outcomes, use your graduate-level critical/evaluative thinking skills and the four questions below to guide your reflection about your personal level of achievement
a) In which of these MBA degree program outcomes have achieved significant proficiency? Provide (cite) examples from the work you have done throughout the course of your degree to support your response.
b) Which Learning Outcome(s) did you not achieve proficiency? Where or in what courses or experiences within the course of the MBA degree program did these challenges manifest the most? Explain fully and provide examples.
c) Reflecting on your MBA degree experience, what would you have done differently to overcome the challenges reflected in the learning outcomes in which you judge yourself to have less proficiency?
Lastly, as you conclude the paper, state your overall assessment of the program; its content, delivery and relevance to your professional/career goals. Based on this encompassing assessment, would you recommend the program to an individual considering it?
This assignment is graded on the basis of how well you support the evaluative statements and conclusions you make. It is NOT scored on the favorability of the comments – so, your candid, honest reflection on your growth in personal knowledge, skills and abilities as well as relevance of the learning to YOU is the true value of completing this assignment.
