The linking of a function with an object during compile time is called static binding. C# provides two techniques to implement static polymorphism: Function overloading and Operator overloading.In Function Overloading, you can have multiple definitions for the same function name in the same scope.Examplevoid print(int i) {    Console.WriteLine("Printing int: ...

Interfaces define properties, methods, and events, which are the members of the interface. Interfaces contain only the declaration of the members. It is the responsibility of the deriving class to define the members.Abstract classes to some extent serve the same purpose, however, they are mostly used when only a few ... Read More

As we know that in MySQL by default || operator is a logical OR operator but it depends upon PIPES_AS_CONCAT SQL mode. If PIPES_AS_CONCAT SQL mode is enabled, then || operator works as string concatenation. At that time its precedence would be between ^ and the unary operator. Following example ... Read More

As we know that, by using a conditional expression within SUM() function we can get the number of rows that meet the condition. So, in this case, MySQL evaluates to 1 each time the condition is true and 0 each time it is false.To understand it, consider the following example ... Read More

The virtual keyword is useful in modifying a method, property, indexer, or event. When you have a function defined in a class that you want to be implemented in an inherited class(es), you use virtual functions. The virtual functions could be implemented differently in different inherited class and the call ... Read More
