Explanation:
- Headers and Structure:
- Includes
iostreamfor input and output operations andiomanipfor formatting. - Defines the
Particlestructure withx,yfor position,vx,vyfor velocity, andax,ayfor acceleration.
- Includes
- updateParticle Function:
- Updates the particle’s velocity based on its acceleration (
ax,ay) and time step (dt). - Updates the particle’s position based on its velocity and the time step.
- Updates the particle’s velocity based on its acceleration (
- main Function:
- Prompts the user to input the particle’s initial position, velocity, acceleration, time step, and number of simulation steps.
- Runs a simulation loop where it updates the particle’s state and prints its position at each step.
