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.
It doesn't matter if you know the number of iterations or not, the for-loop is the same. Here is an example:for (leave= 0; ! leave; ) {/* read from file, on EOF set leave= 1; */}Yes. The for loop is not constrained to be used for simple counting tasks. You can, for example, have the control variable be a pointer an walk it through a tree. All you need to know is that the loop expression is executed at the end, followed by the test expression. Nothing in the spec says these have to be integer counting variables.
Definite interations: Repeated sequence of calculations/ operations for a fixed number of repetitions. (Do or For loop) Indefinite iteration: no set limit on iterations, generally "while" loops. multiple interations is the same as multiple repetitions or trials.
In the Central Processing Unit (CPU).
if (condition) statement1 [else statement2] example: if (i==j); else if (j==k) printf ("i!=j, j==k\n); else printf ("i!=j, j!=k\n); here statement1 is an empty-statement, statement2 is another if-statement There are three forms of statements IF-THEN IF-THEN-ELSE IF-THEN-ELSIF Sequence of statements is executed only if the condition evaluates to TRUE If condition evaluates to FALSE or NULL, it does nothing In either case control passes to next statement after the IF-THEN structure IF THEN statements; END IF; Sequence of statements in the ELSE clause is executed only if the condition evaluates to FALSE or NULL IF THEN statements; ELSE statements; END IF;
A do while loop is executed at least one time.

To determine the number of iterations a loop runs in Java, you can use a counter variable that increments each time the loop runs. You can also use a conditional statement to check when the loop should stop running. By keeping track of the counter variable, you can determine the total number of iterations the loop has executed.
an infinite number.
The time complexity of a while loop is O(n), where n represents the number of iterations the loop performs.
The time complexity of a while loop is O(n), where n represents the number of iterations it takes to complete the loop.
the multiplication of the number of iterations with the number of statements in that loop is equal to loop length.
The time complexity of using a while loop inside a for loop is O(nm), where n is the number of iterations of the for loop and m is the number of iterations of the while loop.
Definite interations: Repeated sequence of calculations/ operations for a fixed number of repetitions. (Do or For loop) Indefinite iteration: no set limit on iterations, generally "while" loops. multiple interations is the same as multiple repetitions or trials.
A number or expression that can be multiplied to get another number or expression is called a factor.
If you're only sorting 3 elements, it should take you 0 to 2 iterations. Of course, this answer might change if you're trying test out a scalable sorting algorithm.
