Some languages may use a different naming convention for this type of loop. For example, the Pascal and Lua languages have a "repeat until" loop, which continues to run until the control expression is true and then terminates. In contrast a "while" loop runs while the control expression is true and terminates once the expression becomes false.
Repeat loop may refer to: For loop – Commonly known as the repeat (x) { ... } loop. Do while loop – Known as the repeat { ... } until (!CONDITION) loop.
The repeat statement repetitively executes a block of one or more statements through an until statement and continues repeating unless the condition is false. The main difference between the two is the while loop may execute zero times if the condition is initially false, the repeat-until loop always executes at least once.
UNTIL repeat a section of code while the specified condition is true. The condition may be evaluated before each iteration of the loop, or after. Both of these commands are found mostly in later dialects. DO ... LOOP {WHILE} or {UNTIL} repeat a section of code indefinitely or while/until the specified condition is true.
A conditional loop has the potential to become an infinite loop when nothing in the loop's body can affect the outcome of the loop's conditional statement. However, infinite loops can sometimes be used purposely, often with an exit from the loop built into the loop implementation for every computer language , but many share the same basic ...
REPEAT – start of a REPEAT/UNTIL loop structure; UNTIL – defines the loop condition for a REPEAT/UNTIL loop structure, and marks its end; RCOMP – reinstates the most recently used IF/THEN/ELSE conditional; LOOP – defines the start of a loop that will run until an EXIT IF conditional is true; EXIT IF – the conditional is true, so it ...
The classic example of recursion is in list-sorting algorithms, such as merge sort. The merge sort recursive algorithm will first repeatedly divide the list into consecutive pairs; each pair is then ordered, then each consecutive pair of pairs, and so forth until the elements of the list are in the desired order.
In computer science, a for-loop or for loop is a control flow statement for specifying iteration. Specifically, a for-loop functions by running a section of code repeatedly until a certain condition has been satisfied. For-loops have two parts: a header and a body. The header defines the iteration and the body is the code executed once per ...
