}while(i<10);
The while loop works as follows:{while( [expression is true] ) {//Do this code}}The while loop re-runs until the expression contained within the parentheses is false. Take a look at this example:{while(!place_meeting(x,y,obj_ground)) {y += 1;}}This while loop tells the object to move down one pixel until it collides with obj_ground. Unfortunately, nothing guarantees that this loop will not run forever. Always make sure that when you construct a while loop that you make sure that it does not run forever. Take a look at this whileloop:{while(obj_ball.y < y) {draw_sprite(sprite_index,0,x,y);}} This while loop will run for ever. Why? It does not have any statements that insure that the while loop aborts. Again, Always make sure that when you construct a loop that you put statements in the loop that will eventually abort the loop. y -= 1; is the statement in this new while loop that eventually aborts the loop:{while(obj_ball.y < y) {draw_sprite(sprite_index,0,x,y); y -= 1;}}
while, do...while, for, foreach are used
While--wend statement is used to execute a loop until a given condition is true.if the condition is false the loop ends and the program continous to the line following eend.
simple code example: <? while ($a < 10 ) { echo "$a, "; $a++; } echo "Finished"; ?> Will output, 1, 2, 3, 4, 5, 6, 7, 8, 9, Finished this will run through the loop WHILE $a is less than 10, outputting the value of $a to the screen. once $a = 10 then the loop will end and continue on with the rest of the script
There are a number of different ways to loop using PHP. They're as follows:ForForeachWhileDo-whileBelow are some examples of how each of these types of loop work.ForForeachWhileDo-while
// Infinite while loop while(true) { System.out.println("Still looping..."); } // More useful while loop to move through all elements in a Queue Object currentItem; while((currentItem = queue.poll()) != null) { System.out.println(currentItem); }
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.
They both loop
// Examples of five Loop structures in C# // Each one iterates over the characters in a string, and writes // them to the Console. string s = "This is a test"; // For Loop for (int i=0; i<s.Length; i++) Console.Write (s[i]); // Foreach Loop foreach (char c in s) Console.Write (c); // While Loop int i=0; while (i<s.Length) Console.Write(s[i++]); // Do Loop int j=0; do Console.Write(s[j++]) while j<s.Length; // Spaghetti Code int k=0; loop: Console.Write(s[k++]); if (k<s.Length) goto loop;
A Do-While loop looks like this: do { loop body } while (condition); and a While loop looks like this: while (condition) { loop body } The main difference is that the loop body is always run once in the Do-While loop, then the condition is checked to see if the loop should keep running. In a While loop, the condition is checked first, and it will not run the loop body at all if the condition is false.
Is loop
A Loop is a programming language construct that instructs the processor to repeat a sequence of operations a number of times until a specific condition is reached. There are different types of loops. They are: * for loop * while loop * do while loop
A preconditional loop is a type of loop that checks a condition before executing its body. If the condition evaluates to true, the loop's statements are executed; if false, the loop is skipped entirely. This ensures that the loop may not run at all if the initial condition is not met. Common examples of preconditional loops include "while" loops in programming.
There are 3 type of loop 1 is for loop 2 is loop while 3 is loop untile
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.
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 .
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.
