Question No.2: Research our planet population growing issues online. Get approximations for the current population and its growing rate (the percentage by which its likely to increase this year). Write a program that calculates

a) World population growtheach year for the next 25 years, using the supposition that the current growth rate will remain unchanged.

b) Print the results in a table. The first column should display the year from year 1 to year 25. The second column should display the anticipated world population at the end of that year. The third column should display the numerical increase in the world population that would occur that year.

Create a program that exercise this function by obtaining a Fahrenheit value from the user, calling the function, and displaying the value of Celsius it returns.
