Project

Object-oriented programming (OOP) has been around for decades. As the original object-oriented language, C# is a mainstay in the world of computer programming.

All the concepts of object-oriented programming that C# developers love to have in their arsenal are explained in detail along with relevant coding examples and exercises in this course.

This course is unique in its nature as it follows a project-based learning approach. Throughout the course, a real-world example of vending machine is followed to help the learners develop a firm understanding of the stated OOP concepts.

The learners will not only be able to play around with the project,  they’ll also be able to see all the concepts in action in this project.

# Problem Statement

A class can have multiple parameterized constructors which can call each other.

You are given a partially completed code of a `VendingMachine` class in the editor. Implement a new parametrized constructor by making use of the already declared constructor which assigns values to all the declared fields.

For the ease of understanding, all the fields are declared as `string` irrespective of the type of data they store.
## Input
_count, _capacity, _moneyCollected

## Output
When the parameterized constructor that you implemented, is called, the declared fields should be initialized accordingly.

## Sample Input

```C#
VendingMachine vendy = new VendingMachine("Count: 45", "Capacity: 50", "Money Collected: 440$");
```

## Sample Output
All the fields should store the respective data.



Can you call a constructor from another constructor? A solution is placed in the "show solution" section to help you, but we would suggest you try to solve it on your own first.
