-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.

 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.
 
-To detect the collision, the function should ask for the coordinates of the obstacle and the car's $$Y$$ coordinate. Remember that the car does not move on the $$X$$ axis, since that coordinate is fixed and stored in a constant variable called `CARX`. The collision occurs if the obstacle has the same $$X$$ coordinate, and is a certain distance above and below the car's $$Y$$ coordinate as shown in Figure 1. The range of the distance of the car's center upwards and downwards is stored in the variable called `OBSTACLERANGE`.
