Explanation

Headers:
- <iostream>: For input and output operations.
- <vector>: For using the std::vector container.
- <cstdlib>: For rand() and srand()
  
  functions.
- <ctime>: For time() function to seed the random number generator.
AutonomousVehicle Class:
- Attributes:
  - x and y: Current position of the vehicle.
  - goalX and goalY: Goal position for the vehicle to reach.
  - grid: 2D grid representing the environment with obstacles.
- Methods:
  - void move(): Moves the vehicle towards the goal. If the vehicle encounters an obstacle, it randomly chooses a different direction.
  - bool hasReachedGoal() const: Checks if the vehicle has reached the goal position.
  - void printPosition() const: Prints the current position of the vehicle.
Main Function:
- Initialization:
  - Seeds the random number generator.
  - Defines grid dimensions and initializes the grid with empty spaces and some obstacles.
  - Creates an AutonomousVehicle object with a starting position, goal position, and the grid.
- Simulation Loop:
  - Runs until the vehicle reaches the goal.
  - Prints the current state, moves the vehicle, and displays the new position.
- Completion:
  - Prints a message when the goal is reached.

Notes:

Basic Movement: The vehicle moves towards the goal and avoids obstacles by randomly changing direction if an obstacle is encountered.

Obstacle Avoidance: This simple example shows basic obstacle avoidance by randomly choosing a new direction. More advanced algorithms would involve pathfinding techniques like A* or Dijkstra’s algorithm.
Simulation: This program provides a foundational example of autonomous vehicle movement and can be expanded with more sophisticated behaviors and decision-making processes.
