Group 2/12 Problem – Population
Create an application that predicts the approximate size of a population of organisms. The application
should use textboxes to allow the user to enter the starting number of organisms, the average daily
population increase (as a percentage), and the number of days the organisms will be left to multiply.
Use a ListBox to display the population size for each day of the simulation.
If the user clicks the Save button, save the current prediction to a file.
Group 3/7 Problem – Dice Simulator
C# Windows Form Application .net
You are a Windows developer for a data analysis company. For one of your applications you need to create a keyword searching form that asks for a filename and a keyword from the user (as shown in below figure). The form should search for the keyword in the file and display the number of lines that contain the keyword in the results group box. Your form assumes that the entered keyword is a single word. If it is not a single word, you need to create and throw an exception for that case.
