Chapter 9, Problem 9.12PE
(Geometry: intersecting point) Suppose two line segments intersect. The two endpoints for the first line segment are (x1 , y1) and (x2, y2) and for the second line segment are (x3, y3) and (x4, y4). Write a program that prompts the user to enter these four endpoints and displays the intersecting point. As discussed in

1) Simple Calculator: In Python, implement a simple calculator that does the following
operations: summation, subtraction, multiplication, division, sqrt, power, natural log and abs.
a) Follow the instructions below:
To work with the calculator, the user is asked to enter the first number, then the
operation, and finally, a second number if required.
Your code has to recognize the need for the second number and ask for it if required.
After performing one operation, the calculator prints the output of the operation.
After performing one operation, the calculator must not exit. It has to start again for
the next operation.
The calculator will be closed if the user writes 'e' as any input.
Use functions to perform the operations and the appropriate conditions to prevent
common errors such as entering characters as one of the numbers etc.
b) Run your code and provide the results for at least one example per operation.

(IN C LANGUAGE) Cumulative Addition: Computer selects a number between 7 and 23 at random. User will only add 2, 3 or 5 numbers to reach that number.For example: To reach 14:
User will enter 5 5 2 2 (4 input).Also he can enter 2 2 2 2 2 2 2 (7 input) or 3 3 3 3 2 (5 input).

Problem-1: Check if an integer is Prime
An integer greater than 1 is prime if its only positive divisor is 1 or itself. For
example, 2, 3, 5, and 7 are prime numbers, but 4, 6, 8, and 9 are not.
Key idea: To test whether a number is prime, check whether it is divisible by 2, 3,
4, and so on up to number/2. If a divisor is found, the number is not a prime. The
algorithm can be described as follows:
Use a boolean variable isPrime to denote whether
the number is prime; Set isPrime to true initially;
for (int divisor = 2; divisor <= number / 2; divisor++) {
if (number % divisor == 0) {
Set isPrime to false
Exit the loop;
}

- (Game: scissor, rock, paper) Write a program that plays the popular scissor–rock–paper game. Rules: A scissor can cut a paper, a rock can knock a scissor, a paper can wrap a rock. The program should randomly generates a number 0, 1, or 2 representing scissor, rock, and paper. The program should prompt the user to enter a number 0, 1, or 2 and displays a message indicating whether the user or the computer WINs, LOSEs, or DRAWs.arrow_forward"NEED ONLY CODE NO EXPLANATION" Harry has a big wall clock, that got hit while he was playing. Now, the minute hand doesn't rotate by the angle 2π/3600 each second, but now it moves according to different angle x. You can assume that coordinates of the centre of the clock are (0, 0) and the length of the minute hand is l. One endpoint of the minute hand is always located at the clock centre; the other endpoint is initially located at the point (0, l). One second later, Harry observes that this endpoint is at distance d above the x-axis, i.e., the y-coordinate of this endpoint is equal to d. Harry is curious about where the minute hand will be (specifically, its y-coordinate) after t seconds. Because t can be very large, Harry can't wait for that moment.

E.g., lottery = 123, input = 123(2) If the user input matches the lottery, but in wrong order, print "the award is $6,000". E.g., lottery = 123, input = 321(3) If two digits in the user input matches a digit in the lottery, print "the award is $3,000". E.g., lottery = 123, input = 612(4) If one digit in the user input matches a digit in the lottery, print "the award is $1,000".

- 4) Roll the dice 2 Make a program that tests the probability of a certain score when rolling x dice. The user should be able to choose to roll eg 4 dice and test the probability of a selected score eg 11. The program should then do a number of simulations and answer how big the probability is for the selected score with as many dice selected. There must be error checks so that you cannot enter incorrect sums, for example, it is not possible to get the sum 3 if you roll 4 dice.

We can easily determines how many different rectangles (squares are excluded) there are in the grid. For example, in a 3X3 grid, you can find 22 different rectangles, marked as the green rectangles. You can see that we did not count the red ones as they are squares. In this assignment, you will write a Java program that takes the value of N as input and determines the total area of all the rectangles in the grid. Assume that the smallest squares in the grid have length 1. So a 3X2 rectangle will have an area of 6. For example, the total area of all the rectangles in the 3X3 grid is 66.…arrow_forward4- Write a program that reads the average of 30 students and find the number of pass students , the number of fail students then print the results. 5- Write a program that reads 20 numbers then find the number of negative and positive numbers and the number of numbers equal to zero and print the results. 6- Write a program to read three numbers A,B,C then find whether A,B,C can form the sides of a triangle, if yes compute the parameter of the triangle , if no print the massage ( not a triangle), then determine whether A,B,C form the side of an (a)) equilateral triangle ,b) isosceles triangie ,c)) right angle triangle Hint: ( A,B,C can form a triangle if each side is less than the sum of the other two sides)arrow_forward

Allow the user to specify a number of random points to be generated inside of the triangle. For each random point that is within the boundaries of the triangle draw a small dot at each of the points that are halfway between the randomly generated point and each vertex of the triangle.

Each cabin is 1 meter long. Sadly, some cabins are broken and need to be repaired. You have an infinitely long repair tape. You want to cut some pieces from the tape and use them to cover all of the broken cabins. To be precise, a piece of tape of integer length t placed at some positions will cover segments 5,5+1-sit-1. You are allowed to cover non-broken cabins, it is also possible that some pieces of tape will overlap. Time is money, so you want to cut at most k continuous pieces of tape to cover all the broken cabins. What is the minimum total length of these pieces?
