Explanation
- Stock Class:
- Attributes:
name: Name of the stock.price: Current price of the stock.
- Methods:
updatePrice(): Updates the stock price with a random percentage change between -5% and +5%. Ensures the price does not go below zero.printInfo(): Prints the current stock name and price, formatted to two decimal places.
- Attributes:
- Main Function:
- Random Number Generation:
srand(time(0))seeds the random number generator to ensure different results each run. - Stocks Initialization: Creates a list of
Stockobjects with initial prices. - Simulation Loop: Runs for a set number of steps (10 in this case). For each step:
- Updates the price of each stock.
- Prints the updated stock information.
- Waits for 1 second to simulate time passing.
- Random Number Generation:
Usage
- Stock Simulation: The program simulates price changes for stocks, providing a basic model of stock market trends.
- Price Fluctuations: The
updatePrice()method applies random changes to simulate market fluctuations.
