Chapter 3.8, Problem 38SC
In the Sherlock Holmes story “The Adventure of the Sussex Vampire”, the inimitable detective uttered these words: “Matilda Briggs was not the name of a young woman, Watson, ... It was a ship which is associated with the giant rat of Sumatra, a story for which the world is not yet prepared.” Over a hundred years later, researchers found giant rats in Western New Guinea, another part of Indonesia.
Suppose you are charged with writing a program that processes rat weights. It contains the statements
System.out.print("Enter weight in kg:");
double weight = in.nextDouble();
What input checks should you supply?

CODE USING C++
Did you know that in lotteries, a 3-digit number with the same numbers in all digits like 777 will hit the jackpot in a casino? In the same manner, let's make a program that will test if a certain 3-digit number hits a jackpot or not by identifying if all the digits of a given number is the same as the second inputted number. If it is, print "Jackpot!"; else, print "Nah".
Let's try this out now!
Input
A line containing two integers separated by a space.
777·7
Output
A line containing a string.
Jackpot!
write a program in C++ that A user needs to determine the size of squares (let say delta) in a grid, the center of the circle (does not have to lie on a grid but it can!) and the radius.
(for example use "cin>>" )
Then you need to plot a circle using parametric equations of circle (you need to increase angle and plot these (in my picture black) points).
First plot the first point of the circle and determine in which square of grid it is. (in my picture it is an orange square) and plot the left bottom vertex of this square (in my picture it is a blue point).
Then increase an angle and plot next point of circle - check if it lies in different square.
-If it is not in different square, you need to increase angle and check again. (because an angle was too small)
-If it is the different square, then check, if this square has THE COMMON EDGE with the previous one -> if it has the common edge, then print new left bottom vertex of this square (if does not have common edge,…
For C++ how do I write a program that plays a word game with the user? The program asks the user to enter the following: His or her name, age, college, profession, type of animal, and a pet's name. The inputs are then inserted into a story as follows:There once was a person named (NAME) who lived in (CITY). At the age of (AGE), (NAME) went to college at (COLLEGE). (NAME) graduated and went to work as a (PROFESSION). Then, (NAME) adopted a(n) (ANIMAL) named (PETNAME). They both lived happily ever after!

- The Research team led by Bernadette Wolowitz at Cal-tech University has discovered a new Amoeba that grows in the order of a Fibonacci series every month. They are exhibiting this amoeba in a national. conference. They want to know the size of the amoeba at a particular time instant. If a particular month's index is given, write a program to display the amoeba's size.

Specifically, if the first half of the word does contain a 't' or a 'T', your program should output a 1. If the first half does not contain the letter 't' or 'T', but the second half does, then your program should output a 2. Otherwise, if there is no 't' or 'T' in the word at all, your program's output should be -1. You may assume that the word entered does not have more than 50 letters.arrow_forwardImagine you are working for a lumber company, and your employer would like a program that calculates the cost of lumber for a customer order.

The price per board foot is given in the following table: Pine 0.89 Fir 1.09 Cedar 2.26 Maple 4.50 Oak 3.10 The lumber is sold in different dimensions (specified in inches of width and height, and feet of length) that need to be converted to board feet. For example, a 2 x 4 x 8 piece is 2 inches wide, 4 inches high, and 8 feet long, and is equivalent to 5.333 board feet (2 * 4 * 8 = 64, which when divided by 12 = 5.333 board feet).

- Please answer it in Python Suppose we play a game where each round takes place in the following way: first, we roll a dice, and its result gives the number of points at stake. Then, the player can, if he wishes, trigger his bonus "double account" or his bonus "triple account". Then, the player answers a number of questions, and calculates his percentage of correct answers. The points awarded to the player for that round are then calculated based on the percentage of correct answers and the number of points in play rounded to the nearest integer (for example, with 50% correct answers and 6 points in play, the player gets 3 points; with 45% correct answers and 8 points in play, the player gets 4 points). Finally, this number of points is possibly multiplied by two or three if the corresponding bonus has been used.
