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
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.
Yes. The same goes for for-loop and 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 .
while(predicate1) { while(predicate2) { ... } }
