Write a program that will predict the size of a population of organisms. The program should ask the user for the starting number of organisms, their average daily population increase (as a percentage, expressed as a fraction in decimal form: for example 0.052 would mean a 5.2% increase each day), and the number of days they will multiply. A loop should display the size of the population for each day.
Prompts, Output Labels and Messages.The three input data should be prompted for with the following prompts: "Enter the starting number organisms: ", "Enter the daily increase: ", and "Enter the number of days the organisms will multiply: " respectively. After the input has been read in successfully, a table is produced, for example:
-----------------------------
2 300.0
4 675.0
Under the heading is a line of 29 dashes followed by one line for each day, showing the day number and the population at the beginning of that day.
Input Validation.Do not accept a number less than 2 for the starting size of the population. If the user fails to satisfy this print a line with this message "Invalid. Must be at least 2. Re-enter: " and try to read the value. Similarly, do not accept a negative number for average daily population increase, using the message "Invalid. Enter a non-negative number: " and retrying. Finally, do not accept a number less than 1 for the number of days they will multiply and use the message "Invalid. Enter 1 or more: ".
