code for c# prog.

Question

The popul ation of a town a is less than the population of town b. However, the population of town a is growing faster than the population of town b. Write a program that prompts the user to enter the population and growth rate of each town. The program outputs after how many years the population of town a will be greater than or equal to the population of town b and the population of both the towns at that time.( a sample input is population of town a = 5000, growth rate of town a =4%, population of town b = 8000, and growth rate of town b=3%).

Try this: using System; class Program { static void Main() { Console.Write("Enter population of town A : "); int popA = int.Parse(Console.ReadLine()); Console.Write("Enter growth rate % of town A : "); double growthA = double.Parse(Console.ReadLine()); Console.Write("Enter population of town B : "); int popB = int.Parse(Console.ReadLine()); Console.Write("Enter growth rate % of town B : "); double growthB = double.Parse(Console.ReadLine()); int n = 0; while (popA { n++; popA = (int)Math.Round(popA * (100.0 + growthA)/ 100.0); popB = (int)Math.Round(popB * (100.0 + growthB)/ 100.0); } Console.WriteLine("
Population of town A >= population of town B after {0} years", n); Console.WriteLine("Population of town A then will be {0}", popA); Console.WriteLine("Population of town B then will be {0}", popB); Console.ReadKey(); } } Sample input/output: Enter population of town A : 5000 Enter growth rate % of town A : 4 Enter population of town B : 8000 Enter growth rate % of town B : 3 Population of town A >= population of town B after 49 years Population of town A then will be 34169 Population of town B then will be 34052

We are in fact using a loop, namely the while() statement, which keeps on increasing the populations of the two towns and incrementing the number of years 'n' until A's population is greater than or equal to B's population.
