While Loop. Console.WriteLine("D) break"); ");       break; }   else Console.WriteLine("Incorrect! The program should display: 25, 20, 15, 10, and 5. break; The main difference here is the condition is tested after the body of the loop and the statement in the body will be executed at least once whether the condition is true or false . if (choice == "c") the number of times the loop body is needed to be executed is known to us.The while loop in C/C++ is used in situations where we do not know the exact number of iterations of loop beforehand. The for loop While Loop in C A while loop is the most straightforward looping structure.

See the example below: What is the command keyword to exit a loop … So, the body of the loop is entered and i is printed and incremented. choice = input.nextLine(); The process goes on until the test expression is evaluated to false. (4 Points) Console.WriteLine("a.quit"); Test Expression: In this expression we have to test the condition. Enter your choice: b Related course: Complete Python Programming Course & Exercises. Use a while loop and a counter, such as counter = 1 … To perform a particular task or to run a specific block of code several times, the concept of LOOP comes in picture. 3. Console.WriteLine("d. exit"); See the example below: What is the Exercises provided by HolyPython.com offer a great way to practice Python and they are free! static void Main(string[] args) The while loop requires relevant variables to be ready, in this example we need to define an indexing variable, i, which we set to 1. }, using System; We shall talk about the same in the context of MATLAB. Console.WriteLine(); Console.WriteLine(); Scanner input = new Scanner(System.in); Unlike a For Loop, While Loop execution does not depend on iteration count; thus, a While Loop executes indefinitely if the condition never occurs. Then, the test expression is evaluated again. While Loops There are two types of loop in Python: the for loop the while loop While loops are known as indefinite or conditional loops. The Note: remember to increment i, or else the loop will continue forever. The JavaScript Code. Console.WriteLine("Please enter the correct answer:"); WHILE Loop Exercise I have already covered in the previous blog post, in this one, I am going to talk about these Exercises using flowchart and pseudocode. System.out.println("b. continue"); Console.ReadKey(); While loop falls under the category of indefinite iteration.. In programming, loops are used to repeat a block of code until a specified condition is met. It provides flexibility to define loop without initialization and update parts (present in for loop). If the condition evaluates to true then we will execute the body of the loop and go to update expression. Modifications of a while loop Exercises. 1. break; Note: The important point to note when using while loop is that we need to use increment or decrement statement inside while loop so that the loop variable gets changed on each iteration, and at some point condition returns false. } While Loop Do-While For Loop Programming Exercises Exercise-1 Exercise-2 1. } } while (choice.ToUpper() == "Y"); System.out.println("Incorrect!

User input does not work with the embedded compiler (paiza) below. choice = Console.ReadLine(); When the condition becomes false, the program control passes to the line immediately following the loop. The user can choose to continue answering the question or stop answering it. Guess the output of this while loop. The same control statements (break and continue) as are used in for loops can also be used in while loops. While loop – multi matches We are using the same while loop as in the last exercise. } of iterations, the while loop relies on a condition to complete the execution.

Summer 2010 15-110 (Reid-Miller) Loops • Within a method, we can alter the flow of control using either conditionals or loops. The program should display: 25, 20, 15, 10, and 5. When condition returns false, the control comes out of loop and jumps to the next statement after while loop. So, the body of the loop is entered and i is printed and incremented.. Incrementing i is important as this will eventually meet the exit condition. ... there are some situations, when using while-loop is the only way to solve the problem. The function will keep on asking the user for the number until it is valid. It will enhance your programming skills. System.exit(0); Console.WriteLine(); The user can choose to continue answering the question or stop answering it. if(choice.equals("y")) { static void printCharacters(){. } "); The code that is in a while block will execute as long as the while statement evaluates to True. { "); Console.WriteLine("a.quit"); Console.WriteLine("b.continue"); Console.WriteLine("c.break"); Console.WriteLine("d.exit"); while (con=="y") {   Console.Write("Enter your choice:");   choice =Console.ReadLine();   if (choice == "c")   {     Console.WriteLine("Congratulation!
