Write a program that takes a positive integer as the height of the triangle and prints an alphabetical triangle, using lowercase English letters as shown below. Each subsequent row of the triangle should increase in length by two letters. Make sure your program validates the user input. If the user does not input a positive integer, print "Invalid input."

Write a program that reads from the user a character (‘s’ or ‘a’). ∙ If the character is ‘s’, the program reads 4 numbers from keyboard and then finds their sum. ∙ If the character is ‘a’, the program reads 4 numbers from keyboard and then finds their average. ∙ Otherwise, it prints “Wrong character” Sample Run: Sample Run1: Enter a character (s or a): s Input 4 numbers: 10.5 12 31 44 The sum of these 4 numbers is: 97.5 Sample Run2: Enter a character (s or a): a Input 4 numbers: 10 12 31 44 The average of these 4 numbers is: 24.375 Sample Run3: Enter a character (s or a): d Wrong character
Write a program which repeatedly reads several people's height numbers in cm(centimeter) until the user enters "done". Once "done" is entered, print out the max, min, and average of the height numbers. Correct height data should be number between 50cm and 250cm. If the user enters number out of the range, or anything other than a number, detect the mistake and print an error message and skip to the next number. Sample input and output: Enter a height: 300 Invalid input Enter a height: 10 Invalid input Enter a height: 200 Enter a height: good Invalid input Enter a height: 180 Enter a height: 165 Enter a height: done Max: 200.0 Min: 165.0 Average: 181.67
Given the sample code above in generating a random number. Create a program that lets the user play the game of Rock, Paper, Scissors against the computer. The program should work as follows. 1. When the program begins, a random number in the range of 1 through 3 is generated. If the number is 1, then the computer has chosen rock. If the number is 2, then the computer has chosen paper. If the number is 3, then the computer has chosen scissors. (Don't display the computer's choice yet.) 2. The user enters his or her choice of "rock", "paper", or "scissors" at the keyboard. (You can use a menu if you prefer.) 13. The computer's choice is displayed. 4. A winner is selected according to the following rules: a. If one player chooses rock and the other player chooses scissors, then rock wins. (The rock smashes the scissors.) b. If one player chooses scissors and the other player chooses paper, then scissor wins. (Scissors cuts paper.) c. If one player chooses paper and the other player…

Question 1 Write a program that asks the user to enter the number of passengers in an airplane and the weight of baggage for these passengers. Your program should then print the average weight of all baggage; it should also print the weights in reverse order. Sample run: Enter the number of passengers in the airplane: 8 Enter the weights of 8 baggage: 16 45 60 13 24 29 50 30 The average weight of all baggage is 33.375 The entered weights in reverse order are 30 50 29 24 13 60 45 16
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. Make the game menu driven with these options Main Menu ______________ 1)Play Game 2)Exit written in python
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 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…
