The HTML DOM Input Email multiple property returns/sets if input Email should accept multiple emails or not.SyntaxFollowing is the syntax −Returning reference to the multiple objectinputEmailObject.multipleSet multiple property to boolValueinputEmailObject.multiple = boolValueBoolean ValuesHere, “booleanValue” can be the following −booleanValueDetailstrueIt defines that the input email accepts multiple entries.falseIt defines that the input email is not accepying multiple emails and it is also the default value.ExampleLet us see an example of Input Email multiple property − Live Demo Input Email multiple form { width:70%; margin: 0 auto; text-align: center; ...

Here we will see three functions. These functions are trunc(), truncf() and the truncl(). These functions are used to convert floating point values into truncated form.The trunc() FunctionThis function is used to truncate double type value. And return only the integer part. The syntax is like below.double trunc(double argument)Example#include #include main() { double a, b, x, y; x = 53.26; y = 75.86; a = trunc(x); b = trunc(y); printf("The value of a: %lf", a); printf("The value of a: %lf", b); }OutputThe value of a: 53.000000 The value of a: 75.000000The ...

This is a C++ program to print Happy Birthday.AlgorithmBegin Take a str1 which takes the next character of our desired ouput like for H it will be G. Assign the string to a pointer p. Make a while loop till *p != NULL. Go next character of the string print it and after that go the nextposition of string. Print the result. EndExample#include using namespace std; main(){ char str[]="G`ooxAhqsgc`x",*p; p=str; while(*p!='\0') ++*p++; cout
Yes, you can set a variable collection name in MongoDB shell using JavaScript. Let us first create a collection with documents −> db.employeeInformation.insertOne({"EmployeeName":"John Smith", "EmployeeAge":24, "EmployeeSalary":450000}); { "acknowledged" : true, "insertedId" : ObjectId("5cc6d06baf8e7a4ca6b2ad97") }Following is the query to display all documents from a collection with the help of find() method −> db.employeeInformation.find();This will produce the following output −{ "_id" : ObjectId("5cc6d06baf8e7a4ca6b2ad97"), "EmployeeName" : "John Smith", "EmployeeAge" : 24, "EmployeeSalary" : 450000 }Here is the query to set variable collection name in MongoDB shell using JavaScript.Case 1 − Set variable with varThe query is as follows −> var status=db.employeeInformation; ...

No, we cannot declare a top-level class as private or protected. It can be either public or default (no modifier). If it does not have a modifier, it is supposed to have a default access.Syntax// A top level class public class TopLevelClassTest { // Class body }If a top-level class is declared as private the compiler will complain that the modifier private is not allowed here. This means that a top-level class cannot be a private, the same can be applied to protected access specifier also.Protected means that the member can be accessed by any class in the same ...

Enumeration (enum) in Java is a datatype which stores a set of constant values. You can use enumerations to store fixed values such as days in a week, months in a year etc.You can define an enumeration using the keyword enum followed by the name of the enumeration as −enum Days { SUNDAY, MONDAY, TUESDAY, WEDNESDAY, THURSDAY, FRIDAY, SATURDAY }Methods and variables in an enumerationEnumerations are similar to classes and, you can have variables, methods, and constructors within them. Only concrete methods are allowed in an enumeration.ExampleIn the following example, we are defining an enumeration with name ... Read More
The HTML DOM Input Email name property returns a, which is the value of the name attribute of input Email. User can also set it to a new string.SyntaxFollowing is the syntax −Returning string valueinputEmailObject.nameSetting name attribute to a string valueinputEmailObject.name = ‘String’ExampleLet us see an example of Input Email name property − Live Demo Input Email name form { width:70%; margin: 0 auto; text-align: center; } * { padding: 2px; margin:5px; } input[type="button"] { ...

Given with an array of int elements, the task is to arrange the elements in descending order and finding their occurrences.Input : arr[]={1, 1, 1, 2, 2, 2, 3, 3, 4, 5, 6, 7, 7} Output : 7 occurs: 2 6 occurs: 1 5 occurs: 1 4 occurs: 1 3 occurs: 2 2 occurs: 3 1 occurs: 3AlgorithmSTART Step 1 -> input array with elements in sorting order Step 2 -> calculate size of an array by sizeof(a)/sizeof(a[0] Step 3 -> store size in a variable say en Step 4 -> Loop For i=siz-1 ...

Here we will see how to get the modulus of two floating or double type data in C. The modulus is basically finding the remainder. For this, we can use the remainder() function in C. The remainder() function is used to compute the floating point remainder of numerator/denominator.So the remainder(x, y) will be like below.remainder(x, y) = x – rquote * yThe rquote is the value of x/y. This is rounded towards the nearest integral value. This function takes two arguments of type double, float, long double, and returns the remainder of the same type, that was given as argument. ...

To check if value exists for a field in a MongoDB document, you can use find() along with $exists operator. Let us first create a collection with documents −> db.checkIfValueDemo.insertOne({"PlayerName":"John Smith", "PlayerScores":[5000, 98595858, 554343]}); { "acknowledged" : true, "insertedId" : ObjectId("5cc6f507af8e7a4ca6b2ad98") } > db.checkIfValueDemo.insertOne({"PlayerName":"John Doe", "PlayerScores":[]}); { "acknowledged" : true, "insertedId" : ObjectId("5cc6f512af8e7a4ca6b2ad99") } > db.checkIfValueDemo.insertOne({"PlayerName":"Carol Taylor", "PlayerScores":[7848474, 8746345353]}); { "acknowledged" : true, "insertedId" : ObjectId("5cc6f521af8e7a4ca6b2ad9a") } > db.checkIfValueDemo.insertOne({"PlayerName":"David Miller", "PlayerScores":[]}); { "acknowledged" : true, "insertedId" : ObjectId("5cc6f531af8e7a4ca6b2ad9b") }Following is the query to display all documents from a collection with the help ...
