Concept explainers

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.

Write a complete program that:
1. Uses a do...while loop to prompt the user to enter a count that is greater than 1 and less than or equal to 20 then reads
in a count from the keyboard as an integer.
a. If input error occurs or the count the user enters is less than or equal to 1 or greater than 20, output an error.
After outputting an error, clear/ignore the failed input and continue do...while looping until a valid number is
entered.

Overview This program will prompt a user for a start and a limit, it will then while-loop through, doubling the iterator each pass, until the limit is reached. Expected Output Example 1 Enter the start of the loop: Enter the limit of the loop: 25 The current value is 3 The current value is 6 The current value is 12 The current value is 24 The last value of current that was less than 25 was 24 Example 2 Enter the start of the loop: 25 Enter the limit of the loop: 102 The current value is 25 The current value is 50 The current value is 100 The last value of current that was less than 102 was 100 Specifications • You should submit a single file called M5A2.py • It should follow the submission standards outlined here: Submission Standards Your program populate an integer named start using input • Your program populate an integer named limit using input Your program must use an iterator named current Your program must move through the values using a while-loop Tips and Tricks That last…

I can't figure this one out for the life of me. I've been stuck on it for 4 hours now... HELP! The programming language is python Write a program that prompts the user to enter a series of strings, but with each string containing a small integer. Use a while loop and stop the loop when the user enters a zero. When the loop has finished, the program should display: • the number of user inputs (not counting the final zero input). • the total of the integers in the strings entered. • the average of the integers accurate to one decimal place.
In python, A customer in a store is purchasing items. Write a program, using a while loop, that asks for the price of each item, then displays the subtotal of the sale, the amount of sales tax, and the total when the customer is done entering all the items. Assume the sales tax is 7 percent. The customer should be allowed to enter as many items as they wish. The while loop should terminate when the user hit the key (Return) on the keyboard. (Hint: Use a null or empty string). Optionally, if you would like to round the dollar amount to two decimal places, you can use output formatting construct in your print statement. For example: print("Sales tax: ", format(sales_tax, '.2f')) will round to two decimal places. Expected Output: Enter the item price or <ENTER> to end: 22.50Enter the item price or <ENTER> to end: 1.99Enter the item price or <ENTER> to end: 45.30Enter the item price or <ENTER> to end: 70Enter the item price or <ENTER> to end: 5Enter the item…
4. Task 3: Using a nested loop Write a program that takes a bank account balance and an interest rate as an input. And then outputs the value of the account in 5 years. The output should show the value of the account for two different methods of compounding interest: annually and monthly. When compounded annually, the interest is added once per year at the end of the year. When compounded monthly the interest is added in 12 times per year. On annual interest, you can assume that the interest is posted exactly one year from the date of deposit. In other words, you do not have to worry about interest being posted on a specific day of the year, like December 31. Similarly, you can assume monthly interest is posted exactly one month after. Since the account earns interest on the interest, the account should have a higher balance when interest is posted more frequently. Be sure to adjust the interest rate for the time period of the interest. If the rate is 5%, then when posting monthly…

Write a program that uses a while loop to do the following: Repeatedly asks the user to enter a number or -1 to exit the program. Keeps track of the smallest and largest numbers entered so far: You will need a variable for the smallest number and another variable for the largest number. Read the first number the user enters, and if it is not -1 set the smallest and largest variables to that number. Use a loop to gather the remaining input. Each time the user enters a new number that is not -1, compare it to the variables and update them if necessary. When the user enters -1, display the smallest and largest numbers that the user entered. If the user did not enter any numbers before entering -1, then simply exit the program. Run the program and test it on several different sets of values to see if it works. Modify the program to ask the user how many numbers they wish to enter and use a for loop to ask for that many numbers. The sentinel value of -1 should no longer be necessary.
Write 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.
