Homework SourseWrite a program that counts down from 10 Implement your prog
Write a program that counts down from 10. Implement your program first with a while loop. Now implement your program with a for loop. Include both versions in your submission file. Write a program that prints 2^n2n where n goes from 1 to 100. Print one answer per line (note: you are answering the question, how high can you count on 100 fingers). Write your program using a \'for\' loop. Reminder \'**\' is the operator for exponents, so for example 4**3 is 4 to the third power, or 4 * 4 * 4 which equals 64. E.g. 2 4 8 16 .... Extend your guessing game from last week. Write a program that picks a random number from 1-100. Then ask the user to guess a number. Tell the user if the answer is higher or lower than the number they guessed, or if they got the correct answer. Allow them to guess again if they got the guess incorrect. They should be able to guess numbers an infinite number of times until they get the correct answer, at which point your loop will end. To generate a number from 1-100 you will need the following code at the beginning of your program: from random import randint randomNum = randint(1,100) Extra Credit - 5 possible points - Write a program that generates the multiplication table for numbers 1-10. Use two for loops to complete your program. You will need to put one for loop inside of the other for loop. As an extra challenge, see if you can get the indention to look correct. So the output of your program should be: 1 2 3 4 5 6 7 8 9 2 4 6 8 10 12 14 16 18 3 6 9 12 15 18 21 24 27 4 8 12 16 20 24 28 32 36 5 10 15 20 25 30 35 40 45 6 12 18 24 30 36 42 48 54 7 14 21 28 35 42 49 56 63 8 16 24 32 40 48 56 64 72 9 18 27 36 45 54 63 72 81
Solution
Note you please clearly give description abount 2^n2n program and Remainder \'**\".So that I can understand and post the program.And please post the due date also. So that I will post immediately.

Program which display the countdown using while Loop
CountDownUsingWhile.java
public class CountDownUsingWhile {
public static void main(String[] args) {
//Declaring variable
int i=10;
//checking whether the number is greater than zero or not.
while(i>0)
{
//Displaying the number
System.out.println(i);
//Decrementing the \'i\' value by 1 for every iteration
i--;
}
}
}

Progrm which display Multiplication Tables
MultiplicationTable.java
public class MultiplicationTable {
public static void main(String[] args) {
//Thsi nested for loop will print the multiplication table from 1 to 10
for(int i=1;i<10;i++)
{
for (int j=1;j<10;j++)
{
System.out.print(i*j+\" \");
}
}
}
