Answer to Question #336683 in C# for Siyanda

Question

a) Write a method PopulationTotal that accepts 2 positive values, namely the current

population (in millions, e.g. a value of 1.5 means 1.5 million people) and the growth rate (e.g.

0.14 means 14%). The method determines and returns the total population based on the current

population and growth rate. For example, if the current population for a country is 1.165 million

people, and the annual population growth rate is 10%, then the total population is 1.2815 million

people after 1 year.

b) Write a method Over180Million that accepts a positive value representing the population (in

millions). The method determines whether the population is over 180 million people, and returns

a value of true if this is so, otherwise returns a value of false.

Answer 1

internal class Program
    {


        static void Main(string[] args)
        {
            Console.Write("Enter number of people in millions:");
            double people = double.Parse(Console.ReadLine());


            Console.Write("Enter population growth rate:");
            double populatationGrowRate = double.Parse(Console.ReadLine());


            PopulationTotal(people, populatationGrowRate);


            if (Over180Million(people))
                Console.WriteLine("More than 180 million people in the country");
            else
                Console.WriteLine("There are less than 180 million people in the country");
            Console.ReadKey();
        }


        static void PopulationTotal(double people,double rate)
        {
            people += people * (rate / 100);
            Console.WriteLine($"Number of people in the country in a year {people} with population growth {rate}");
              
        }


        static bool Over180Million(double people)
        {
            if(people>=180)
                return true;
            return false;
        }
