For each statements

        
A for each statement is a way to execute a set of statements for each item in a collection.

            A simple for each statement has the form for each item in collection
            followed by a list of statements which will be executed for each item in the collection,
            where item is a variable name and collection is a collection.
            If item already exists, its type must be compatible with the item type of the collection.

        
        

            
        
        

        
Optionally, a for each statement can populate an index variable.
        
        


        

            
        
        


        

            Breaking the iteration
        

        
It is sometimes useful to break the iteration before reaching the end of the collection. This is achieved using the break statement.
