Write a program that asks the user to enter the three sides (a, b and c) of a triangle as double
values. Assume that the user will enter three valid sides that can form a triangle, your program
should perform the following tasks:
If the three sides are equal, the program displays "Equilateral" on the screen.
• If any two sides are equal, the program displays "Isosceles".
If the sum of the squares of any two sides is equal to the square of the third one, for example
(3? + 42 = 5) then the program displays "Right"
• Otherwise, the program displays "Scalene" as well as the perimeter of the triangle which is
the sum of all three sides.
Sample Run 1:
Enter three sides: 4.2 4 5
Sample Run 2:
Enter three sides: 111
Equilateral
Scalene
Perimeter of triangle is: 13.2
Sample Run 3:
Enter three sides: 3 4 5
Right
Sample Run 4:
Enter three sides: 8.2 5 8.2
Isosceles

Write a program that generates a random number in the range from 1 through 100
After generating the random number, the user is to guess the number. If the user’s guess is higher than the random number, the program should display “Too high, try again”
If user’s guess is lower than the random number, the program should display “Too low, try again”.
If the user guesses the number, the program should congratulate the user and then generate a NEW random number so the game can start over.

java Write a program that prompts the user to enter a point (x, y) and checks whether the point is within the rectangle centered at (0, 0) with width 10 and height 5. For example, (2, 2) is inside the rectangle and (6, 4) is outside the rectangle, as shown in the Figure.
(Hint: A point is in the rectangle if its horizontal distance to (0, 0) is less than or equal to 10 / 2 and its vertical distance to (0, 0) is less than or equal to 5 / 2.)
Here are sample runs of the program:
Sample 1:
Enter a point with two coordinates: 2 2
Point (2.0, 2.0) is in the rectangle
Sample 2:
Enter a point with two coordinates: 6 4
Point (6.0, 4.0) is not in the rectangle

- The Fibonacci series is a series that begins with 0 and 1 and has the property that each succeeding term is the sum of the two preceding terms. For example, the third Fibonacci number is 1 which is sum of 0 and 1. The next is 2, which is a sum of 1 + 1.

- Write a program that asks the user to enter the coordinates of 4 points that draw two different lines. The program has to display whether these two lines are parallel, perpendicular, or neither according to the following formula: Slope = 22-y1 x2-x1 If the slopes of both lines are equal, the two lines are parallel If the product of both slopes is equal to -1, the 2 lines are perpendicular. Otherwise, the two lines are neither parallel nor perpendicular. Sample Run Enter the 4 coordinates of first line: 5.7 8.9 7 7.8 Enter the 4 coordinates of second line: 5.7 7.6 3.5 8.9 The two lines are neither parallel nor perpendicular BUILD SUCCESSFUL (total tine: 36 seconds)arrow_forwardIn this assignment you will write a program that shows the valid moves of chess pieces. Your program will draw a board with 64 squares using the traditional layout, next ask the user to choose a move, and then, depending on the user's choice, redraw the board with the selected chess piece and its valid moves. Please see the examples of valid moves of chess pieces and the traditional chess board layout below:arrow_forwardSuppose a right triangle is placed in a plane as shown below. The right-angle point is at (0, 0), and the other two points are at (200, 0), and (0, 100).

- Write a program that does the following: 1. prompts the user to enter a word 2. using that word, first prints out the word where all characters are replaced by “_”’s (there will be an example to better illustrate this below). 3. the program will continue to print the word revealing one character at a time. i.e., The second line printed should print the first character followed by “_”’s representing the rest of the word. 4. The program should end after printing the entire word once Example: Enter a word: kangaroo ________ k_______ ka______ kan_____ kang____ kanga___ kangar__ kangaro_ kangaroo Note: you will have to use nested loops in this problem.arrow_forwardWrite a program that prompts the user to enter three cities and displays them in ascending order.arrow_forwardWrite a program that does the following: 1. prompts the user to enter a word 2. using that word, first print out the word where all characters are replaced by “_”’s (there will be an example to better illustrate this below). 3. the program will continue to print the word revealing one character at a time. i.e., The second line printed should print the first character followed by “_”’s representing the rest of the word. 4.

- Write a program that asks the user to enter two integers: n1 and n2 and prints the sum of all numbers from n1 to n2. For example, if the user enters n1=3 and n2=7, then the program should display the sum as 25.arrow_forwardWrite a program that lets the user guess whether a randomly generated integer would be even or odd. The program randomly generates an inte- ger and divides it by 2. The integer is even if the remainder is 0, otherwise odd. The program prompts the user to enter a guess and reports whether the guess is correct or incorrect.arrow_forwardTo make telephone numbers easier to remember, some companies use letters to show their telephone number. For example, using letters, the telephone number 438-5626 can be shown as GET LOAN. In some cases, to make a telephone number meaningful, companies might use more than seven letters. For example, 225-5466 can be displayed as CALL HOME, which uses eight letters. Write a program that prompts the user to enter a telephone number expressed in letters and outputs the corresponding telephone number in digits. If the user enters more than seven letters, then process only the first seven letters. Also output the - (hyphen) after the third digit. Allow the user to use both uppercase and lowercase letters as well as spaces between words. Moreover, your program should process as many telephone numbers as the user wants.arrow_forward
