Whenever possible, use for instead of foreach.
Notable languages without foreach are C, and C++ pre-C++11.
In languages like C, there is no concept of a foreach loop.
Instead of the Java“foreach” loops for looping through an iterator, Scala has a much more powerful concept of for-expressions.
We are not andwill be not inside a foreach loop.
However, the foreach statement in C can operate on any object providing such a method, even if it doesn't implement IEnumerable.
As you probably figured by now,the magic happens on the foreach block.
However, the foreach statement in C can operate on any object providing such a method, even if it doesn't implement IEnumerable duck typing.
However, it has several standard data structures that can be used as collections, and foreach can be made easily with a macro.
One foreach macro cannot be defined that works with different collection types(e.g., array and linked list) or that is extensible to user types.
The J2SE 5.0 release of Java introduced the Iterable interface to support an enhanced for(foreach) loop for iterating over collections and arrays.
Unlike other for loop constructs, however, foreach loops usually maintain no explicit counter: they essentially say"do this to everything in this set", rather than"do this x times".
The two main interfaces for implementation in PHP scripts that enable objects to be iterated via the foreach loop are Iterator and IteratorAggregate.
Instead of the Java"foreach" loops for looping through an iterator, Scala has for-expressions, which are similar to list comprehensions in languages such as Haskell, or a combination of list comprehensions and generator expressions in Python.
A trivial example iterates over an array of integers: A more complex example iterates over an associative array of arrays of integers:Tcl uses foreach to iterate over lists.
The following shows a simple use of iterators in C 2.0:// explicit version IEnumerator iter= list. GetEnumerator(); while(iter. MoveNext()) Console. WriteLine(iter.Current);// implicit version foreach(MyType value in list) Console. WriteLine(value); C 2.0 also supports generators: a method that is declared as returning IEnumerator(or IEnumerable), but uses the"yield return" statement to produce a sequence of elements instead of returning an object instance, will be transformed by the compiler into a new class implementing the appropriate interface.
The next example illustrates a PHP class that implements the Traversable interface,which could be wrapped in an IteratorIterator class to act upon the data before it is returned to the foreach loop.
Iterators in Python are a fundamental part of the language andin many cases go unseen as they are implicitly used in the for(foreach) statement, in list comprehensions, and in generator expressions.
This iteration is a boolean expression which is true if all items in my_list have counts greater than three: across my_list as ic all ic. item. count> 3 end The following is true if at least one item has a count greater than three: across my_list as ic some ic. item. count>3 end Go's foreach loop can be used to loop over an array, slice, string, map, or channel.
