-In almost every instance in which we want to solve a problem, we select among are one or more options that depend on whether certain conditions are met. Computer programs are built to solve problems, therefore they should have a structure that allows them to make decisions and select alternatives. In C++, selections are structured using `if`, `else`, `else if` or `switch`. Relational expressions and logical operators are common when handling selection structures. In this laboratory experience you will practice the use of certain selection structures to complete the design of a car and an obstacle collision game application.

 The first step in this laboratory experience is to familiarize yourself with the pre-defined functions (methods) in the code. You will invoke some of these functions in the code to detect the collisions.

 In this exercise you will use the C++ condition structure called **switch** to change the attributes of the track. You will complete the `setTrack` method that can be found in the `work.cpp` file. This method changes the environment of the track depending on the value of `track_type` that is given as a parameter.

 In this exercise you will complete the `obstacleCollision` method that can be found in the `work.cpp` file. The function receives an object of the `Obstacle` class and another object of the `Car` class, and should detect if there is a collision or not between the car and the obstacle. The function returns true if there is a collision between the car and an obstacle, and false if there is no collision.

 In this exercise you will complete the `flagCollision` method that can be found in the `work.cpp` file. The function receives an object of the `Obstacle` class and another object of the `Car` class, and should detect if there is a collision or not between the car and the flag. This function is very similiar to the function in Exercise 3, except that the function does not return a value. The actions that occur when a collision is detected are done inside the function.
