The Array.LongLength property gets a 64-bit integer that represents the total number of elements in all the dimensions of the Array.Let’s say your array of long data type is −long[,] arr1= new long[15, 35];Use the LongLength property to get an integer representing the total number of elements in all dimensions of the Array −arr1.LongLengthLet us see an example to implement the Array.LongLength property of array class −Example Live Demousing System; class Program { static void Main() { long[,] arr1= new long[15, 35]; long len1 = arr1.GetLongLength(0); Console.WriteLine(len1); Console.WriteLine(arr1.LongLength); } }Output15 525
For this purpose, we create an object of HashMap class which is defined in java.util packageMap map = new HashMap();This hashmap object associates each digit with its corresponding word representationmap.put("0", "zero");Initialize an empty string object.String newstr="";Next, run a for loop over the length of given string and extract each character by substring() method of String class.Check if the character exists as a key in map object by containsKey() method. If it does, using it as key, obtain its value component in map and appenf\d to the new string. If not append the character itself to the new string. The complete code ... Read More
For adding a new user to MySQL, we just need to add a new entry to the user table in the database mysql. To illustrate it we are using the following example −ExampleThe following program is an example of adding a new user guest with SELECT, INSERT and UPDATE privileges with the password guest123; the SQL query is −root@host# mysql -u root -p Enter password:******* mysql> use mysql; Database changed mysql> INSERT INTO user (host, user, password, select_priv, insert_priv, update_priv) VALUES ('localhost', 'guest', PASSWORD('guest123'), 'Y', 'Y’, 'Y'); Query OK, 1 row affected (0.20 sec) mysql> FLUSH PRIVILEGES; Query OK, ...

Under Composition, if the parent object is deleted, then the child object also loses its status. The composition is a special type of Aggregation and gives a part-of relationship.For example, A Car has an engine. If the car is destroyed, the engine is destroyed as well.public class Engine { . . . } public class Car { Engine eng = new Engine(); ....... }Aggregation is a directional relation between objects in C#. It is the relationship between objects.For example, Employee and AddressAn Employee is associated with a single Department, whereas a Department can have more than one employee. Let ... Read More
The mechanism of linking a function with an object during compile time is called early binding. It is also called static binding. C# provides two techniques to implement static polymorphism i.e Function overloading and Operator overloading.Let us learn about Function Overloading with an example −You can have multiple definitions for the same function name in the same scope. The definition of the function must differ from each other by the types and/or the number of arguments in the argument list. You cannot overload function declarations that differ only by return type.The following is the complete example −Example Live Demousing System; ... Read More
The following are the unary operators in C# −+ - ! ~ ++ -- (type)* & sizeofLet us learn about the sizeof operator. The sizeof returns the size of a data type.Let’s say you need to find the size of int datatype −sizeof(int)For double datatype −sizeof(double)Let us see the complete example to find the size of various datatypes −Example Live Demousing System; namespace Demo { class Program { static void Main(string[] args) { Console.WriteLine("The size of int is {0}", sizeof(int)); Console.WriteLine("The size of int is ...

The User defined data types in C# are structures and enumeration.StructureIn C#, a structure is a value type data type. It helps you to make a single variable hold related data of various data types. The struct keyword is used for creating a structure.The C# structures have the following features −Structures can have methods, fields, indexers, properties, operator methods, and events.Structures can have defined constructors, but not destructors. However, you cannot define a default constructor for a structure. The default constructor is automatically defined and cannot be changed.Unlike classes, structures cannot inherit other structures or classes.Structures cannot be used as ... Read More
We can also add user account by using GRANT SQL command. It can be illustrated by using the following example −ExampleIn this example, we will add user Zara with password zara123 for a particular database,which is named as TUTORIALS.root@host# mysql -u root -p password; Enter password:******* mysql> use mysql; Database changed mysql> GRANT SELECT,INSERT,UPDATE,DELETE,CREATE,DROP -> ON TUTORIALS.* -> TO 'zara'@'localhost' -> IDENTIFIED BY 'zara123';The above statements will also create an entry in the MySQL database table called as a user.
Aggregation is a directional relation between objects in C#. It is the relationship between objects.For example, Employee and AddressAn Employee is associated with a single Department, whereas a Department can have more than one employee. Let us see an example of Employee and Address −public class Address { . . . } public class Employee { private Address addr; public Employee (Address addr) { this.addr = addr; } . . . }
To make a jQuery function call after “X” seconds, use the siteTimeout() method.On button click, set the following and fade out the element. Here, we have also set the milliseconds. This is the delay that would occur before fading an element:$("#button1").bind("click",function() { setTimeout(function() { $('#list').fadeOut();}, 4000); });You can try to run the following code to learn how to work with setTimeout() method in jQuery:Example Live Demo $(document).ready(function(){ $("#button1").bind("click",function() { setTimeout(function() { $('#list').fadeOut();}, 4000); }); }); India US UK The above data will fade out after 4 seconds
