Answer / sourisengupta
OverLoading :- Method Name remains the same with different
signatures.
For ex:- Take a method name vehicle.
if u are passing two parameters to it , it will generate
informations for 2 wheelers .
if u are passing four parameters to it, it will generate
informations for 4 wheelers.
shortly we can tell same with different characteristics.
Overriding : - Method name and signatures must be same.
In overriding user can change the behaviour of the method
for the derived class.

If P is the population on the first day of the year, B is the birth rate, and D is the death rate, the estimated population at the end of the year is given by the formula: The population growth rate is given by the formula: B – D Write a program that prompts the user to enter the starting population, birth and death rates, and n, the number of years. The program should then calculate and print the estimated population after n years. Your program must have at least the following functions: 1. growthRate: This function takes its parameters the birth and death rates, and it returns the population growth rate. 2. estimatedPopulation: This function takes its parameters the current population, population growth rate, and n, the number of years. It returns the estimated population after n years Your program should not accept a negative birth rate, negative death rate, or a population less than 2. please answer my question ....
