Within a method, we can alter the flow of control using either conditionals or loops. The loop statements while, do-while, and for. allow us execute a statement(s) over and over. Like a conditional, a loop is controlled by a boolean expression that determines how many times the statement is executed. E.g.,
while loops. for loops. We’ve already seen some examples of flow charts that contain loops: Structures where the algorithmic flow loops back and repeats process steps. Repeats as long as a certain condition is met, e.g., toaster has not popped up, toast is inedible, etc.
The do...while loop is a variant of the while loop with one important difference: the body of do...while loop is executed once before the condition is checked. Its syntax is: do { // body of loop; } while (condition);
do...while loop. The do..while loop is similar to the while loop with one important difference. The body of do...while loop is executed at least once. Only then, the test expression is evaluated. The syntax of the do...while loop is: do { // the body of the loop } while (testExpression);
29 sie 2024 · The do…while loop is guaranteed to execute the statements in the body of the loop at least once as it is a type of exit-controlled loop. Can we skip braces in C do…while loop syntax if there is only one statement in the body?
A DO WHILE loop is similar to an IF block, except that: unlike an IFblock, when a DO WHILE loop encounters its END DO statement, it jumps back up to the associated DO WHILE statement; unlike an IFblock, a DO WHILE loop can have only one clause, which is analogous to the IF clause; a DO WHILE loop cannot have anything analogous to an ELSE IF clause
