7.23 LAB: Winning team (classes)

Given main(), define the Team class (in files Team.h and Team.cpp). For class member function GetWinPercentage(), the formula is:
teamWins / (teamWins + teamLosses)

Note: Use casting to prevent integer division.

Ex: If the input is:

Ravens 13 3

where Ravens is the team's name, 13 is number of team wins, and 3 is the number of team losses, the output is:

Congratulations, Team Ravens has a winning average!

If the input is Angels 80 82, the output is:

Team Angels has a losing average.

### Lab Activity: Winning Team (Classes)

**Current File: Team.cpp**

#### Description

This programming task focuses on implementing a class for managing sports teams. The primary goal is to define and implement necessary functions that handle and manipulate team data.

#### Code Overview

```cpp
#include "Team.h"

// TODO: Implement mutator functions -
// SetTeamName(), SetTeamWins(), SetTeamLosses()

// TODO: Implement accessor functions -
// GetTeamName(), GetTeamWins(), GetTeamLosses()

// TODO: Implement GetWinPercentage()
```

#### Task Details

1. **Mutator Functions**:
- **SetTeamName()**: Define a function to set the team name.
- **SetTeamWins()**: Define a function to update the team's wins.
- **SetTeamLosses()**: Define a function to update the team's losses.

2. **Accessor Functions**:
- **GetTeamName()**: Create a function to retrieve the team name.
- **GetTeamWins()**: Create a function to get the number of wins.
- **GetTeamLosses()**: Create a function to get the number of losses.

3. **Win Percentage Calculation**:
- **GetWinPercentage()**: Implement a function to calculate and return the winning percentage of the team based on wins and losses.

This lab activity is designed to help students practice class design and implementation, focusing on encapsulation and data handling in C++.

# 7.23.1: LAB: Winning Team (Classes)

**Current File: Team.h**

This code is a header file for a C++ class named `Team`. It outlines the structure for a class that models a sports team with basic attributes and functions. Below is a detailed explanation of the components:

```cpp
#ifndef TEAMH
#define TEAMH

#include <string>

class Team {
// TODO: Declare private data members - teamName, teamWins, teamLosses

// TODO: Declare mutator functions -
// SetTeamName(), SetTeamWins(), SetTeamLosses()

// TODO: Declare accessor functions -
// GetTeamName(), GetTeamWins(), GetTeamLosses()

// TODO: Declare GetWinPercentage()
};

#endif
```

### Code Explanation

1. **Header Guards**:
- `#ifndef TEAMH` and `#define TEAMH` prevent multiple inclusions of the header file in different parts of the program, avoiding potential errors.

2. **Include Statement**:
- `#include <string>` is necessary for using the `std::string` type, which will store the team's name.

3. **Class Declaration**:
- `class Team { ... };` defines a class named `Team`.

4. **TODO Sections**:
- **Private Data Members**: Intended for storing the team's name, the number of wins, and the number of losses.
- **Mutator Functions**: These functions will allow setting the values of the team's name, wins, and losses.
- **Accessor Functions**: These will enable retrieving the values of the team's name, wins, and losses.
- **GetWinPercentage()**: This function should calculate and return the winning percentage of the team based on wins and losses.

### Purpose
This header file is part of a lab activity designed to teach students how to create and work with classes in C++. The students are expected to implement the private data members and functions, which encapsulate the data and provide interfaces for interacting with the `Team` objects.
