These statements are commonly called loops. If the Boolean expression is true, the control jumps back up to do statement, and the statements in the loop … initially, the initialization statement is executed only once and statements(do part) execute only one. The Iteration statements in C++ and Java are, for loop, while loop and do while loop. 2. Using the do-while loop, we can repeat the execution of several parts of the statements. This loop will execute the code block once, before checking if the condition is true, then it will repeat the loop as long as the condition is true. A do while loop is a control flow statement that executes a block of code at least once, and then repeatedly executes the block, or not, depending on a given boolean condition at the end of the block. If the test expression is false, the loop ends. C nested do while loop. Loop is used to execute the block of code several times according to the condition given in the loop. The body of do...while loop is executed at least once. The do..while loop is similar to the while loop with one important difference. The value of i is then incremented to 2. The syntax of a do...while loop in C++ is −. The do-while loop . The following example uses Do…while loop to check the condition at the end of the loop. Active 11 months ago. Overview. C++ do…while Loop. The C++ do-while loop is executed at least once because condition is checked after loop body. If you want to check the condition after each iteration, you can use do while loop statement. In do-while loop, the test condition is evaluated at the end. On the other hand in the while loop, first the condition is checked and then the statements in while loop … Such situations can be handled with the help of do-while statement evaluates the body of the loop first and at the end, the condition is checked using while statement. When the number is negative, the loop terminates; the negative number is not added to the sum variable. It will execute the group of statements inside the C Programming loop. Do While Loop In C: C Tutorial In Hindi #13 In the previous tutorial, we learned the basic concept of the loops in C. In today’s tutorial, we will see the do-while loop in detail, along with an example. The C while loop is used when you want to execute a block of code repeatedly with a checked condition before making an iteration. Next >> Syntax of do while do { statements; }while(expression); do while loop has similar behavior as while loop but it has one difference. In this tutorial, we will learn about while and do..while loop. do-while-loop in C-Programing <
