Write a program that reads from the user a character ('q' or 'c').
If the character is 'c', the program reads from the user the radius rof a circle and prints its area.
• If the user enters 'q', the program asks the user to enter the length and width of a quadrilateral. We
assume the quadrilateral is either a square or rectangle. You should print if the quadrilateral is square
or rectangle.
• Otherwise, it prints "Wrong character"
PS: Use the following formulas:
area of circle=3.14*r
Sample Run1:
Enter a character (q or c): q
Enter the Length and Width: 80 150
|It is a rectangle
Sample Run2:
Enter a character (q or c): q
Enter the Length and Width: 80 80
It is a square
Sample Run3:
Enter a character (q or c): c
Enter the radius: 2
The area of the circle is 12.56
Sample Run4:
Enter a character (q or c): d
Wrong character
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.

Write a program that generates a plate number based on the user's answer to the following questions:
1. What is your favorite color of the rainbow (ROYGVIB)?
a. Use the first letter of the chosen color as the first character of the plate number.
b. Display "Invalid Input" and ask the user to re-enter his/her answer if the answer is not a valid color of the rainbow.
2. What is your month of birth?
a.
Use the last letter of the month as the second character of the plate number.
b. Display "Invalid Input" and ask the user to re-enter his/her answer if the answer is not a valid month.
3. What is your first name?
a. Use the third letter of the first name as the third character of the plate number. No need to include the second name if you have a second name.
Make sure to use "cout" and "cin" to collect the necessary inputs from the user.
For the number section:
1. Ask the user his/her age and use the age as the first and second digits of the plate number.
a. Display "Invalid Input" and ask…

- 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.)

The program should ask the user to enter a number from 1-6 and the corresponding hangman should be printed. The value the user inputs corresponds to the number of incorrect guesses in a real hangman game and so the completeness of the hangman will correspond to the number of ‘incorrect guesses’ inputted by the user (e.g., if the user enters 1, then only the head of the hangman will be printed; full example below). Example:Enter a number from 1-6: 1O Enter a number from 1-6: 2O|Enter a number from 1-6: 3O\||Enter a number from 1-6: 4O\|/|Enter a number from 1-6: 5O\|/|/Enter a number from 1-6: 6O\|/|/ \ 2. Modify your program from problem 1 so that the user input is checked to be a validsingle digit (1-6) before printing the corresponding hangman. If the input is not valid, theninstead of a hangman the following message should be printed “Invalid input: you must enter asingle number from 1-6.” Example:Enter a…arrow_forwardWrite a program in python Suppose a right triangle is placed in a plane as shown below.

Your program will ask the user to input a number 0, 1, or 2 to denote rock, paper, and scissors respectively. Your program will then randomly generate a number 0, 1, or 2 to denote the computer’s hand. The rules for the game are: •A scissor can cut paper. •A rock can knock a scissor. •A piece of paper can wrap a rock. Let the game run continuously until either the user or the computer wins 3 times, displaying the outcome of each hand. At the end of the game, display a message indicating whether the user or the computer wins Helpful Hint: import random player2= random.randint(0, 2)arrow_forward
- Display the first N magic numbers, where N is a positive number that the user provides as input. Here, a magic number is a number whose sum of its digits eventually leads to 1. For example, 1234 is a magic number because 1 + 2 + 3 + 4 = 10 and 1 + 0 = 1, while 1235 is not (1 + 2 + 3 + 5 = 11 and 1 + 1 = 2). Write a program that prints out the first N magic numbers, seven on each line. You are required to use the following function prototype: bool isMagic(int value); // Returns true if value is a magic number The outline of this function will be as follows: Step 1: Calculate the sum of digits of the value Step 2: Repeat Step 1 until we get a single-digit Step 3: If the resulting sum is equal to 1 then it is a magic number, otherwise not Here is the sample output:arrow_forwardf. A laborant in a laboratory does a number of antigen tests in one day. Write a program that simulates the number of antigen tests done in a day in a laboratory, displays the number of positives and negatives, and calculates the % of positives in one day. Your program needs to first generate a random number that will show the number of tests done in a day. One laboratory in a day cannot do more than 100 tests and less than 1 (they do at least one). Then for each of the tests, your program needs to generate a random number to show whether they are positive or negative. In order to write this program, you need to have the following three functions used by the main function: test result (void): This function generates a test result. It should randomly return either one or zero. 1 means positive test result and 0 means negative test result. float positive percentage (int,int) : This function takes the total number of positives and the total number of tests and returns the % of positives.…arrow_forwardThis example creates a program to teach a first grade child how to learn subtractions. The program randomly generates two single- digit integers number1 and number2 with number1 > number2 and displays a question such as "What is 9 – 2?" to the student. After the student types the answer, the program displays a message to indicate whether the answer is correct.arrow_forward
