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 ...
Roblox occasionally hosts real-life and virtual events. They have in the past hosted events such as BloxCon, which was a convention for ordinary players on the platform. [45] Roblox operates annual Easter egg hunts [51] and also hosts an annual event called the "Bloxy Awards", an awards ceremony that also functions as a fundraiser. The 2020 ...
foreach loop [ edit ] The foreach statement is derived from the for statement and makes use of a certain pattern described in C#'s language specification in order to obtain and use an enumerator of elements to iterate over.

The following demonstrates enumeration using a foreach loop: // loop through the collection and display each entry. foreach ( KeyValuePair < string , string > kvp in dictionary ) { Console . WriteLine ( "Phone number for {0} is {1}" , kvp .
Specifically, the for loop will call a value's into_iter() method, which returns an iterator that in turn yields the elements to the loop. The for loop (or indeed, any method that consumes the iterator), proceeds until the next() method returns a None value (iterations yielding elements return a Some(T) value, where T is the element type).
The more correct form is for-loop with the hyphen (as well as while-loop, do-loop, do-while-loop, repeat-loop, foreach-loop, etc.), for exactly the reasons stated by NickyMcLean. The same goes for other constructs, such as if-then-else, do-while, repeat-until, try-catch, test-and-set, etc. It is indeed confusing to parse a sentence such as "for ...
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 ...
