Challenge Problem (pyhton)
T E S T S C O R E S
Write a program that implements a test scores program. Valid test score entries are between 0 and 100 inclusive.
The program should
display a welcome message and run everything through the "main" function.
have the ability to enter several test scores (try a loop) and print out the total score, as well as, the average score.
continuously ask for test scores until the number 99.9 has been entered.
test for valid entries and the value 99.9. If a test score is valid, the program should add the current score to the total score and update the number of test scores by one (+1), otherwise it displays an error message.
Note :
This assignment involves the use of a while loop and if-else decision making controls.
You CANNOT use the reserved keywords break and continue for any portion of this program or any program for that matter throughout this course.
1. In the first loop, the low number will be the starting point for the loop and thehigh will be the ending point. The loop should display the iterator number andthat number x 10 on the same line, separated by a tab. See example on p. 177.2. The second loop should accumulate all the numbers between the starting pointand ending point. You will need to create and initialize an accumulator such astotal before you start the loop.
LAB: Warm up: Text analyzer & modifier (1) Prompt the user to enter a string of their choosing. Output the string. (1 pt) Ex: Enter a sentence or phrase: The only thing we have to fear is fear itself. You entered: The only thing we have to fear is fear itself. (2) Complete the GetNumOfCharacters() function, which returns the number of characters in the user's string. We encourage you to use a for loop in this function. (2 pts) (3) In main(), call the GetNumOfCharacters() function and then output the returned result. (1 pt) (4) Implement the OutputWithoutWhitespace() function. OutputWithoutWhitespace() outputs the string's characters except for whitespace (spaces, tabs). Note: A tab is '\t'. Call the OutputWithoutWhitespace() function in main(). (2 pts) Ex: Enter a sentence or phrase: The only thing we have to fear is fear itself. You entered: The only thing we have to fear is fear itself. Number of characters: 46 String with no whitespace: Theonlythingwehavetofearisfearitself.

Directions: Design a program with a loop that lets the user enter a series of names (in no particular order). After the final person’s name has been entered, the program should display the name that is first alphabetically and the name that is last alphabetically. For example, if the user enters the names Kristin, Joel, Adam, Beth, Zeb, and Chris, the program would display Adam and Zeb. Additional requirements: Note that the possible set of input values can include negative, 0, or positive values, but not the sentinel value of -99. DESIGN HINT: • When determining the largest (or smallest) value in a set of numbers, remember to use variables to keep track of the current largest (or smallest) number found thus far. These variables can then be used as a comparison to each subsequent input number to see if the new number is larger (or smaller) than the current largest (or smallest) number and updated appropriately.

- Using c++Random Number Guessing Game Write a program that generates a random number between 1 and 100 and asks the user to guess what the number is. If the user’s guess is higher than the random number, the program should display “Too high. Try again.” If the user’s guess is lower than the random number, the program should display “Too low. Try again.” The program should use a loop that repeats until the user correctly guesses the random number. Then the program should display “Congratulations. You figured out my number.” Enhance the program so it keeps a count of the number of guesses the user makes. When the user correctly guesses the random number, the program should display the number of guesses along with the message of congratulations.arrow_forwardGameAA.java This program allows a user to play “Rock, paper, scissors” against the computer. Use a random number generator to generate the computer’s selection. Your code should ask the user what they choose and then report the computer’s choice and who wins. This code should run in a loop and should end when the user chooses to end. (Make sure your random number generator chooses a new number each time the loop runs.) ALSO, your code should keep track of the number of times you win, the number of times you lose, and the number of ties. When the user exits, these statistics should be displayed. (Consider using a different counter variable to keep track of each value.) Make sure your code accounts for inputs that are out of the acceptable range. For example, if you ask the user to type 0 to end, 1 for Rock, 2 for Paper, and 3 for Scissors, your code should tell the user that they entered an invalid choice if they select 4.
