Start the day with a tall (at least 500 ml) glass of water as soon as you wake up. Imagine going an entire work day without drinking. Your body does the equivalent of this every night when you sleep. Many Canadians are starting the day dehydrated, which leads to fatigue very early on in the day., she says.
IEnumerable and IEnumerator. When using C# with the .NET framework version 1.1, you can create classes that behave like collections or arrays. If you wish to use the foreach loop structure to iterate through the values in your class, you must implement the IEnumerable interface. This interface contains a single method, named GetEnumerator, which returns an enumerator object.
A class can extend one other class and implement any number of interfaces. An interface can extend any number of interfaces. When a class implements an interface it implements all of the methods declared in that interface. You can have variables and parameters of an interface type. method in Java that has a parameter of interface type is nearly the same as a function template in C++. A class that uses interfaces to type any variables or parameters behaves very similarly to a class template in C++. Just think of the interface names as if they were template arguments.
