1. Create a project and get the following program to run:

//DISPLAY 2.1 A C++ Program#include<iostream>using namespace std;intmain( ) {intnumber_of_bars;doubleone_weight, total_weight; cout <<"Enter the number of candy bars in a package\n"; cout <<"and the weight in ounces of one candy bar.\n"; cout <<"Then press return.\n"; cin >> number_of_bars; cin >> one_weight; total_weight = one_weight * number_of_bars; cout << number_of_bars <<" candy bars\n"; cout << one_weight <<" ounces each\n"; cout <<"Total weight is "<< total_weight <<"ounces.\n"; cout <<"Try another brand.\n"; cout <<"Enter the number of candy bars in a package\n"; cout <<"and the weight in ounces of one candy bar.\n"; cout <<"Then press return.\n"; cin >> number_of_bars; cin >> one_weight; total_weight = one_weight * number_of_bars; cout << number_of_bars <<" candy bars\n"; cout << one_weight <<" ounces each\n"; cout <<"Total weight is "<< total_weight <<" ounces.\n"; cout <<"Perhaps an apple would be healthier.\n";return0; }

2. Now add a new variable calories_per_bar. What should be the type?

3. Add an input prompt to get the calories. Ad an input statement to get a values or calories.

4. Add a statement to compute the total number os calories given the number of candr bars.

5. Print out the total number of calories along with an appropriate message.

6. Assume that the typical bite of a candy bar is 0.7 ounces. Add code to display the number of bites per bar, and the total number of bites for all the bars.

7. **Uninitialized Variables**: Write a program that contains statements that output the value of five or six variables that have been declared, but not initialized. Compile and run the program. What is the output? Explain.
