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. Each item in the given collection will be returned and reachable in the context of the code block.
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 ...
Another term for early-exit loops is loop-and-a-half. 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 ...
C# and VB.NET are very different languages in syntax and history. As the name suggests, the C# syntax is based on the core C programming language originally developed by Dennis Ritchie at Bell Labs (AT&T) in the 1970s. [1] Java and C++ are two other programming languages whose syntax is also based on the C syntax, [2] so they share a common ...
Early BASICs (such as GW-BASIC) used the syntax WHILE/WEND. Modern BASICs such as PowerBASIC provide both WHILE/WEND and DO/LOOP structures, with syntax such as DO WHILE/LOOP, DO UNTIL/LOOP, DO/LOOP WHILE, DO/LOOP UNTIL, and DO/LOOP (without outer testing, but with a conditional EXIT LOOP somewhere inside the loop). Typical BASIC source code:

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.
