What are the advantages of using a foreach loop over a for or while loop for processing list elements?
foreach can simply replace for loop. for ex in perl, if you need to copy display an array, it will take only foreach $var(@arr). then print $var. no need of incrementing the index of array like for loop.
What is the difference between for if-then and for loop?
a for loop is defined with an boolean expression to indicate when it should terminate. A for each loop iterates once for each item in a collection. for example, "for each (book in bookshelf)" will iterate once for each book on the bookshelf, providing access to the current book. a for loop is defined like "for (int i = 0; i<10;i++)" meaning the loop will iterate as long as the condition is true (i < 10), and will increment on each loop. Note: there is no 'for each' loop in C language, but there is a 'foreach' in PHP.

Is it mandatory to use array in foreach loop C-sharp can foreach be used without array?
Foreach is for an IEnumerable, not just an array (unless you are using C# 1.1 or earlier). A collection (List, Dictionary, etc) can also generate a sequence from foreach-statement. In fact, if you have a class that is NOT an array, but it implements all the required methods of IEnumerable, it may be applied as:public class Storage: IEnumerable {...}Storage myStorage = new Storage();...Foreach (Thing stuff in myStorage){...}
What is a foreach loop?
A foreach loop takes an array, and goes through the loop you specify - each time, it goes to the next index of the array. When it has gone through every index, the script continues. This can be useful to retrieve data from a database, and insert it into a table, list, or into general content space, or to easily manipulate all the data in an array. The syntax varies depending on the programming language you are using.
