Explanation:

Headers and Function Declaration:
- Includes iostream for input and output operations and iomanip for formatting the output.
- Declares the simulatePopulationGrowth function which handles the simulation of population growth.
simulatePopulationGrowth Function:
- Takes three parameters: initialPopulation (starting population), growthRate (rate of population increase), and years (number of years to simulate).
- Initializes the population variable with initialPopulation.
- Prints the header for the year and population.
- Uses a loop to iterate over the number of years, updating the population each year based on the growth rate, and printing the year and updated population.
main Function:
- Prompts the user to input the initial population, growth rate, and number of years.
- Calls the simulatePopulationGrowth function with the provided inputs to display the population growth over time.
