Explanation

Constants:
- SPEED_OF_SOUND: The speed of sound in air at 20°C, set to 343 m/s. This is the reference speed used in the Doppler effect calculations.
calculateDopplerEffect Function:
- This function calculates the observed frequency based on whether the source and observer are moving towards or away from each other.
Main Function:
- The program prompts the user to input the source frequency, source speed, observer speed, and whether the observer is moving towards or away from the source.
- Based on the input, the program calls calculateDopplerEffect to determine the observed frequency and displays the result.

Usage

Source Frequency: The frequency of the sound emitted by the source (e.g., a siren).

Source Speed: The speed at which the source is moving.
Observer Speed: The speed at which the observer is moving.
Direction: Whether the observer is moving towards or away from the source.
