Here we will see how to write a code where two functions are present, and one function will be executed before the main function, and another function will be executed after main function. These features are used to do some startup task before executing main, and some clean up task after executing main.To do this task we have to put attribute for these two functions. When the attribute is constructor attribute, then it will be executed before main(), and when the attribute is destructor type, then it will be executed after main().We are using GCC functions. The function is __attribute__(). ... Read More
The task is to print the given n number which have exactly two set bits that neither less than 2 nor more than 2.Set bits in computer language are the one that have value 1 and unset bits have value as 0Input: value of num=5 Output: 1 3 5 As 1 is equivalent to 1 in binary 3 is equivalent to 11 in binary 5 is equivalent to 101 in binaryAlgorithmSTART Step 1 -> declare variable as unsigned int num=5 and int i=1 Step 2 -> print i Step 3 -> Loop For i=3 and i
Modeless dialog boxes are on the screen and are available for use.

In this program we will see how to perform modulus of the first array corresponding to the next array.Problem StatementWrite 8086 Assembly language program perform modulus of the first array corresponding to the next array.DiscussionIn this example there are two different arrays. The arrays are stored at location 501 onwards and 601 onwards. The size of these two arrays are stored at offset location 500. We are taking the array size to initialize the counter, then by using loops we are getting the modulus of the elements one by oneInputAddressData……500045010F5020B5030550408……601046020A6030260403……Flow DiagramProgram MOV SI, 500 ;Point Source index ...

You can use find() for this. Let us first create a collection with documents −> db.findInDictionaryDemo.insertOne( ... { ... "_id":101, ... "AllCustomerDetails": ... { ... "SomeCustomerDetail1": ... { ... "CustomerName1":"John Doe", ... "CustomerName2":"John Smith" ... }, ... "SomeCustomerDetail2": ... { ... "CustomerName1":"Carol Taylor", ...

For this, work with the concept of forEach(). Let us first create a collection with documents −> db.printDocuementValueDemo.insertOne({"InstructorName":"John Smith"}); { "acknowledged" : true, "insertedId" : ObjectId("5cd6804f7924bb85b3f48950") } > db.printDocuementValueDemo.insertOne({"InstructorName":"Sam Williams"}); { "acknowledged" : true, "insertedId" : ObjectId("5cd680577924bb85b3f48951") } > db.printDocuementValueDemo.insertOne({"InstructorName":"David Miller"}); { "acknowledged" : true, "insertedId" : ObjectId("5cd680637924bb85b3f48952") }Following is the query to display all documents from a collection with the help of find() method −> db.printDocuementValueDemo.find().pretty();This will produce the following output −{ "_id" : ObjectId("5cd6804f7924bb85b3f48950"), "InstructorName" : "John Smith" } { "_id" : ObjectId("5cd680577924bb85b3f48951"), "InstructorName" : "Sam Williams" } ...

You need to switch the database to admin. Following is the syntax −use adminThe syntax is as follows for shutdown option −db.shutdownServer()Let us implement the above syntax for shutdown −> use admin switched to db admin > db.shutdownServer()This will produce the following output −server should be down... 2019-04-22T19:11:40.949+0530 I NETWORK [js] trying reconnect to 127.0.0.1:27017 failed 2019-04-22T19:11:42.197+0530 I NETWORK [js] reconnect 127.0.0.1:27017 failed failed
The getColumnType() method of the ResultSetMetaData (interface) retrieves the type of the specified column in the current ResultSet object.This method accepts an integer value representing the index of a column and, returns an integer value representing the SQL type of the specified column.Following is the list of values returned by various datatypes of java.sql.Type −Array: 2003Big int: -5Binary: -2Bit: -7Blob: 2004Boolean: 16Char: 1Clob: 2005Date: 91Datalink70Decimal: 3Distinct: 2001Double: 8Float: 6Integer: 4JavaObject: 2000Long var char: -16Nchar: -15NClob: 2011Varchar: 12VarBinary: -3Tiny int: -6Time stamt with time zone: 2014Timestamp: 93Time: 92Struct: 2002SqlXml: 2009Smallint: 5Rowid: -8Refcursor: 2012Ref: 2006Real: 7Nvarchar: -9Numeric: 2Null: 0Smallint: 5To get the ResultSetMetaData ...
