The while loop will stop iterating if its condition is no longer true when it reaches the end of an iteration, or if it encounters a break statement.

What is expression that is executed by the for loop only once regardless of the number of iterations?

In a for loop, the expression that is executed only once, regardless of the number of iterations, is the initialization expression. This expression is typically found at the beginning of the loop's syntax and is used to initialize the loop variable. For example, in the loop for (int i = 0; i < n; i++), the initialization int i = 0 is executed just once before the loop begins iterating.


What looping process checks the test condition at the end of the loop?

The do..while() loop tests the condition at the end of the loop. Therefore the loop body executes at least once. The while() loop (without do) tests the condition before entering the loop and before each iteration of the loop. The for() loop conditional expression is optional but, when specified, is tested before entering the loop and before each iteration of the loop.


Why you need a for loop when you have already while loop or do while loop?

We need a for loop because the while and do-while loops do not make use of a control variable. Although you can implement a counter inside a while or do-while loop, the use of a control variable is not as self-evident as it is in a for loop. Aside from the use of a control variable, a for loop is largely the same as a while loop. However, it is quite different to a do-while loop, which always executes at least one iteration of the loop before evaluating the conditional expression. In a for and while loop, the conditional expression is always evaluated before entering the loop, which may result in the loop not executing at all.


Which pair of loops causes a statement or set of statements to repeat as long as a condition is true?

A while loop repeats until the condition becomes false, and may never execute: int a = 4; while (a > 5) { //Do something } or int a = 4; while (a > 0) { //Do something a--; }


What the difference between pretest loop and posttest loops?

The difference is that pre means before and post means after in Latin so it's tested before or after. :)

Can you Compare while and do-while?

The 'while' statement evaluates its expression at the beginning of the loop, while a 'do while' statement evaluates its expression at the end of the loop. The 'while' statement might execute no times. The 'do while' statement will execute at least one time. It depends on what you want to do, and on how you want to use the side effects, if any, of the expressions in the expression. (Before or after)


How do you convert a while loop to do-while loop?

A for loop is classified as an iteration statement. A simple example might be... For x = 1 To 10 'loop body Next x The same loop expressed as a while loop (classified as a control flow statement) could be... x = 0 Do While x < 11 'loop body x = x + 1 Loop .

What are sentinental loop c plus plus?

A sentinel loop is a loop that iterates over a series of values until a special "sentinel" value is encountered. For instance, when iterating over the characters in a string, the null-terminator acts as the sentinel value, indicating that the end of the string has been reached. Sentinel loops typically have the following form: while( get_value(value) != sentinel ) { // do something with value... }

What is a nested loop in java?

A nested loop is a (inner) loop that appears in the loop body of another (outer) loop. The inner or outer loop can be any type: while, do while, or for. For example, the inner loop can be a while loop while an outer loop can be a for loop.
