In computer programming, foreach loop (or for-each loop) is a control flow statement for traversing items in a collection. foreach is usually used in place of a standard for loop statement . Unlike other for loop constructs, however, foreach loops [ 1 ] usually maintain no explicit counter: they essentially say "do this to everything in this ...
A generator expression may be used in Python versions >= 2.4 which gives lazy evaluation over its input, and can be used with generators to iterate over 'infinite' input such as the count generator function which returns successive integers:
while loop do while loop (count-controlled) for loop foreach; Ada [1] while condition loop statements end loop: loop statements exit when not condition end loop: for index in «reverse» [first.. last | discrete_type] loop statements end loop: for item of «reverse» iterator loop statements end loop or (for [all | some] [in | of] [first..
The loop counter is used to decide when the loop should terminate and for the program flow to continue to the next instruction after the loop. A common identifier naming convention is for the loop counter to use the variable names i, j, and k (and so on if needed), where i would be the most outer loop, j the next inner loop, etc. The reverse ...
The following example is done in Ada which supports both early exit from loops and loops with test in the middle. Both features are very similar and comparing both code snippets will show the difference: early exit must be combined with an if statement while a condition in the middle is a self-contained construct.
PowerShell is a task automation and configuration management program from Microsoft, consisting of a command-line shell and the associated scripting language.Initially a Windows component only, known as Windows PowerShell, it was made open-source and cross-platform on August 18, 2016, with the introduction of PowerShell Core.

Foreach loop – The FOR and FORFILES commands both implement a for-each loop; find (Unix) – Unix command that finds files by attribute, similar to forfiles; find (Windows) – DOS and Windows command that finds text matching a pattern; grep – Unix command that finds text matching a pattern, similar to Windows find
