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.

In Java A while loop reads integers from input. Write an expression that executes the while loop until a positive integer is read from input. Ex: If the input is -20 -43 -25 -22 15, then the output is:User entered -20User entered -43User entered -25User entered -22Loop terminated while () {

Write code that uses any type of loop. The code should continually ask for a user input and sums all user inputs that are divisible by 2. The loop should continue until the user enters a negative number. The code should output the sum a single time once user entry has completed. You may assume all libraries and namespaces have been previously written into the code, you are just writing everything that would go inside the main function (beyond the return 0:).
Factorials The factorial of n (written n!) is the product of the integers between 1 and n. Thus 4! = 1*2*3*4 = 24. By definition, 0! = 1. Factorial is not defined for negative numbers. Write a program that asks the user for a non-negative integer and computes and prints the factorial of that integer. You'll need a while loop to do most of the work-this is a lot like computing a sum, but it's a product instead. And you'll need to think about what should happen if the user enters 0. 1. 2. Now modify your program so that it checks to see if the user entered a negative number. If so, the program should print a message saying that a nonnegative number is required and ask the user the enter another number. The program should keep doing this until the user enters a nonnegative number, after which it should compute the factorial of that number. Hint: you will need another while loop before the loop that computes the factorial. You should not need to change any of the code that computes the…

"Simon Says" is a memory game where "Simon" outputs a sequence of 10 characters (R, G, B, Y) and the user must repeat the sequence. Create a for loop that compares the two strings starting from index 0. For each match, add one point to userScore. Upon a mismatch, exit the loop using a break statement.
