Types of Loop

Loops are the elements of programming in which a part of code is repeated a particular number of times. Loop executes the series of statements many times till the conditional statement becomes false.

Loops

Any task which is repeated more than one time is called a loop. Basically, loops can be divided into three types as while, do-while and for loop. There are so many programming languages like C, C++, JAVA, PYTHON, and many more where looping statements can be used for repetitive execution.

While Loop

Loop is a feature in the programming language. It helps us to execute a set of instructions regularly. The block of code executes until some conditions provided within that Loop are true.

Question

Task 1: Sentinel controlled loop
Write a program that asks the user for a char input and prints whether the entered character is a vowel or a
consonant.
The program should keep on asking the user until the user enters a negative value (the negative value is our
sentinel value in this case).
Sample Interaction:
Enter a character: A
It is a vowel!
Enter a character: F
It is a consonant!
Enter a character: e
It is a vowel!
Enter a character: -1
That is my sentinel!
Hint: What does all negative values have in common?

Lab 6: Multiplication Table Write a program that will continually ask the user to enter a positive number from standard input and print out the multiplication number table until user enters an alphabet (non number) to quit. Once user enters 'Q' or anything other than a number, the program will print out “Have a nice day" and then exit the program. After reading the user's input the positive number, the program will print out the multiplication table of the inputted number. For example, if user enters 5, the table should be: Multiplication table for 5 is: 2 3 4 5 4 6 8 10 9 12 15 8 12 16 20 5 10 15 20 25 Your program needs continuously ask the user to enter the a positive number until the user enters Q or q to exit the program.

Customized step counter Learning Objectives In this lab, you will Create a function to match the specifications Use floating-point value division Instructions A pedometer treats walking 2,000 steps as walking 1 mile. It assumes that one step is a bit over 18 inches (1 mile = 36630 inches, so the pedometers assume that one step should be 18.315 inches). Let's customize this calculation to account for the size of our stride. Write a program whose input is the number of steps and the length of the step in inches, and whose output is the miles walked. Output each floating-point value with two digits after the decimal point, which can be achieved as follows: print(f'{your_value:.2f}') Ex: If the input is: 5345 18.315 the output is: You walked 5345 steps which are about 2.67 miles. Your program must define and call the following function. The function should return the number of miles walked.def steps_to_miles(user_steps, step_length) # Define your function here if __name__…
Problem Statement for High and Low Design a program that lets the user enter a series of numbers. The user should enter -99 to signal the end of the series. After all the numbers have been entered, the program should display the highest and lowest number in the series. Part 1. Understand the Problem The program will use a while loop to get the numbers from the user. It is not necessary for the individual numbers to be saved;each number can be evaluated as it is read in. To find the highest and lowest number in the series, use two variables. The variables are initialized by getting the first number from the user and assigning it to both the highest and lowest variables. The assumption is, that if there is only one number in the series it is both the highest and lowest numbers. Inside the loop, each number should be compared to the value stored in the highest variable and its value should replace the value in highest variable if it is greater than the number already there. The same can…

Chapter 4 Loops and Files 17. Random Number Guessing Game Write a program that generates a random number and asks the user to guess what the num- ber 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 cor rectly guesses the random number.
program4_2.pyWrite a program that uses a while loop to enable the user to enter any number of positive integers. The loop should end when a sentinel value of 0 (zero) is entered. The program should then report the sum of the even integers and the sum of the odd integers.
Turtle Drawing with Loops Objective: To make a drawing using turtle graphics and nested loops Requirements: -Your program should ask the user at least two questions, and use the answers to help make the drawing. -Your program must have at least one pair of nested loops (a loop inside of a loop) to do some of the drawing -Your drawing cannot be made up only of rotated polygons coming from the center of the screen like we did in class. -Please write a new program for this assignment - don't use code from any in-class exercises. -For example, your program could draw a field of flowers, or you could draw a repetitive square pattern like you might see on a rug.
