Explanation

Constants:
- INITIAL_TEMPERATURE: Starting temperature in degrees Celsius.
- TEMPERATURE_VARIATION: Maximum daily variation in temperature.
- INITIAL_PRECIPITATION: Starting precipitation amount in millimeters.
- PRECIPITATION_CHANCE: Probability of precipitation occurring on any given day.
- MAX_PRECIPITATION: Maximum amount of precipitation that can occur in a day.
- NUM_DAYS: Number of days to simulate.
randomDouble Function:
- Generates a random double between min

  and max using the rand() function.
- This function is used to add variability to temperature and precipitation values.
simulateWeather Function:
- Simulates daily weather patterns for a specified number of days.
- Temperature Update: Each day, the temperature is updated with a random variation.
- Precipitation Update: Each day has a chance of precipitation, with the amount determined if precipitation occurs.
- Outputs the daily temperature and precipitation values.
Main Function:
- Seeds the random number generator with the current time to ensure different results on each run.
- Calls simulateWeather to run the simulation and output the weather patterns for the given number of days.

Usage

Initial Conditions: The simulation starts with a temperature of 20°C and no precipitation.
Temperature Variation: The temperature changes randomly within a specified range each day.
Precipitation Chance: There is a 30% chance each day of some precipitation occurring, with the amount varying up to 20 mm.
