Write a program that asks a user to enters pairs of numbers until they enter "quit". As each pair of numbers is entered and validated, add the numbers using a function. The function will have two parameters for the pair of numbers and will return the sum. After the user enters "quit", output all the pairs of numbers and their sums.

Write a Servlet application that prompts the user for the midterm and final
grades and for output displays its Fall, Spring or Summer grades(Numerical and
letter) depending on the button pressed. Have a link to redo the problem.
Use he following formulas to compute the numerical grade:
if Fall: grade=(2*midterm + final)/3
if Spring: grade=(midterm + 2* final)/3
If Summer: grade=(midterm + final)/2

Write a program called dayofmonth.js that displays how many days are in the month for a given month and year. Use 2 (February) for the month and 2000 for the year.

See Sample Execution Below:

This program will determine the number of days in a given month.

Month (1-12) : 2

Year: 2000

There are 29 days in the month

Suppose you have a certain amount of money in a savings account that earns compound interest, and you want to calculate the amount that you will have after a specific number of months. The formula is as follows:
F = P X (1 + i) ^ t
The terms in the formula are:
F is the future value of the account after the account after the specified time period.
P is the present value of the account.
i is the monthly interest rate.
t is the number of months.
Write a program that executes a loop 5 times. Each step of the loop generate a random value for P, i (between 0 and 10 percent) , and the number of months betwen (1 and 100). The loop should then pass these values to a function that returns the future value of the account, after the specified number of months. The program should display the accounts future value each pass. See sample output below:
Present Value: $500.00
Monthly Interest Rate: .07
Number of Months: 72
Future Value: $65,253.23

A prime number is a number that is only evenly divisible by itself and 1. For example, the number 5 is prime because it can only be divided by 1 and 5. The number 6 however, is not prime because it can be divided evenly by 1, 2, 3, and 6.
Write a Boolean function named isPrime which takes an integer as an argument and returns true if the argument is a prime number of false otherwise. Generate 100 random numbers and display the results of checking each one for primality.
Save this in a script called primes.js.

Create a script called odd_even.js. Write a program that generates 100 random numbers and keeps count of how many of those random numbers are even and how many of them are odd. Sum the even numbers and sum the odd numbers. Use a function to check if a given number is even or odd and use a function that returns the sum of a given array. Display the results as:
Even Number Count: 72
Odd Number Count: 28
Sum Even: 560
Sum Odd: 433

Write a program called population.js, that predicts the approximate size of a population of organisms. The program should use the following data:

Starting number of organisms: 2

Average daily increase: 30%

Number of days to multiply: 10

The program should display the following table of data:

Day Approiximate Population
1 2

2 2.6

3 3.38

4 4.394

5 5.7122

6 7.42586

7 9.653619

8 12.5497

9 16.31462

10 21.209
