Question
python
program a clock using nested repeat loops.
• The minute hand must contain the second hand.
• When the second hand reaches 59, the minute hand has to be increased one by one.
• The maximum value of the clock will be one hour (1:00:00).
• Don't forget to delete variables when 59 is reached.
Expert Solution

arrow_forward
Explanation
1) Below is Python program that implements clock with seconds, minutes and hours
2) It uses nested for loop where
- Define variable to store hours
- External for loop run from 0 to 60 represents minutes
- Internal for loop run from 0 to 60 represents seconds, , after 59 it automatically set to 0
- Display time in hours, mimutes and seconds fromat
- Internal for loop run from 0 to 60 represents seconds, , after 59 it automatically set to 0
- Increment hours after second and minutes loop terminates and display time
2) Save Program in python file and run

- JAVA The loop continuation condition is the inverse of the loop termination condition. True Falsearrow_forward: Write a python program to simulate an online store. The program should begin by displaying a list of products and their prices. There should be a minimum of 4 products offered. The program should ask the user to choose a product and then ask the user to enter the quantity they require of that product. The program should then allow the user to keep choosing more products and quantities until they enter something to indicate they want to end the program (e.g. a given number or ‘q’ or ‘exit’). The program should then tell the user the total amount for the products they have selected.arrow_forwardConstruct a do-while() loop in c, which continues to display the following menu: 1. Add funds to bank account.2. Withdraw funds from back account. 3. Exit and prompt the user for an option, while the option entered by the user is not in the range 1- 3, inclusive. Note: you are constructing an input validation loop. Show all variable declarations.arrow_forward

A random number between 1 and 10 is generated in the program. The user enters a number between 1 and 10, trying to guess the correct number. If the user guesses correctly, the program congratulates the user, and then the loop that controls guessing numbers exits; otherwise, the program asks the user if he or she wants to guess again. If the user enters a "Y", he or she can guess again. If the user enters "N", the loop exits. You can see that the "Y" or an "N" is the sentinel value that controls the loop. Note that the entire program has been written for you. You need to add code that validates correct input, which is "Y" or "N", when the user is asked if he or she wants to guess a number, and a number in the range of 1 through 10 when the user is asked to guess a number. Instructions Ensure the file named GuessNumber.java is open.

You also write the statements that make up the body of the loop. The source code file already contains the necessary variable declarations and output statements. Each theater patron enters a value from 0 to 4 indicating the number of stars the patron awards to the Guide’s featured movie of the week. The program executes continuously until the theater manager enters a negative number to quit. At the end of the program, you should display the average star rating for the movie. Instructions Ensure the file named MovieGuide.java is open. Write the while loop using a sentinel value to control the loop, and write the statements that make up the body of the loop to calculate the average star rating. Execute the program by clicking Run.

In the second choice implement the concept of while loop using break statement d. In the third choice implement the concept of for loop Hint: a) Use switch statement b) Display menu should be like this: *** MENU *** 1. if-else 2. while loop using break 3. for looparrow_forwardMUST BE IN PYTHON PROGRAMMING CODE!!!!! NO C++ or Java!! 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.

When completed, the program should calculate two totals: the number of left-handed people and the number of right-handed people in your class. Your loop should execute until the user enters the character X instead of L for left-handed or R for right-handed. The inputs for this program are as follows: R, R, R, L, L, L, R, L, R, R, L, X Variables have been declared for you, and the input and output statements have been written. Instructions Ensure the file named LeftOrRight.java is open. Write a loop and a loop body that allows you to calculate a total of left-handed and right-handed people in your class. Execute the program by clicking Run and using the data listed above and verify that the output is correct.arrow_forward
