While loop do while loop
The concept of iteration is connected to possibly wanting to repeat an action. Like all control structures we ask a question to control the execution of the loop. The term loop comes from the circular looping motion that occurs when using flowcharting. The basic form of the do while loop is as follows: do.
Hence, this type of Loop is also called a post-checking Loop. FOR Loop is an entry controlled Loop, that is, the control statements are written at the beginning of the Loop structure, whereas, do-while Loop is an exit controlled Loop, that is, the control statements are written at the end of the Loop structure.
Key Differences Between while and do-while Loop. The while loop checks the condition at the starting of the loop and if the condition is satisfied statement inside the loop, is executed. As against, in the do-while loop, the condition is checked after the execution of all statements in the body of the loop. If the condition in a while loop is ...Explanation: In the above code, first of all, we are declaring and initializing a loop counter variable 'loop_ctr' as 1. Next, there is a While statement along with the condition 'While loop_ctr <= 10'. This means that we need to iterate until the value of the 'loop_ctr' variable is less than or equal to 10.Have you ever wondered where your loved ones are when they are flying?

The syntax for a for loop is. 1. 2. 3. for ( variable initialization; condition; variable update ) {. Code to execute while the condition is true. } The variable initialization allows you to either declare a variable and give it a value or give a value to an already existing variable. Second, the condition tells the program that while the ...Execution of do-While loop. Control falls into the do-while loop. The statements inside the body of the loop get executed. Updation takes place. The flow jumps to Condition. Condition is tested. If Condition yields true, go to Step 6. If Condition yields false, the flow goes outside the loop. The flow goes back to Step 2.Hence, even if the condition is not fulfilled, this loop will execute one time. The do-while loop is an example of exit controlled loop. Types of Loop in C.

The following while loop iterates as long as n is less than 3 : js. let n = 0; let x = 0; while (n < 3) {. n++; x += n; } With each iteration, the loop increments n and adds that value to x. Therefore, x and n take on the following values: After the first pass: n = 1 and x = 1. The WHILE loop is called a pretest loop because it checks the search_condition before the statement_list executes. Second, place one or more statements that will execute between the DO and END WHILE.
