AngularJS – ngHref Directive
The ngHref Directive in AngularJS solves the problem of replacing the markup when the link is broken which thus leads the system to return a 404 error. Instead of using markup like {{hash}} in an href attribute which will change or replace the markup value, we should use the ngHref directive since that link can be broken and thus leads to return a System Error.Syntax..content..Example − ngHref DirectiveCreate a file "ngHref.html" in your Angular project directory and copy-paste the following code snippet. ngHref Directive ...

The ngSelected Directive in AngularJS sets the selected attribute element on the element to True. We can also write an expression inside the ngSelected with the only condition that it should evaluate to True.This special directive is necessary since interpolation cannot be used inside the selected attribute.Syntax..content..Example − ngSelected DirectiveCreate a file "ngSelected.html" in your Angular project directory and copy-paste the following code snippet. ngSelected Directive Welcome to Tutorials Point ...
Read MoreAngularJS – ng-switch Directive
The ngSwitch directive in AngularJS conditionally swaps the DOM structure on the template based upon the scope expression. This directive can be used for showing or hiding elements based upon the switch cases.The HTML elements will be displayed only if the expression inside the ngSwitch directive evaluates to True, else it will remain hidden. This directive is supported by all the HTML elements.Syntax Contents... Contents... Contents... Example − ngSwitch DirectiveCreate a file "ngSwitch.html" in your Angular project directory and copy-paste the following code snippet. ...
Read MoreAngularJS – isObject() method
The isObject() method in AngularJS basically checks if a reference is an Object or not. This method will return True if the reference passed inside the function is an Object, else it will return False.Note − NULL values are not considered as an Object, but JavaScript arrays are objects.Syntaxangular.isObject(value)Example − Check if the reference is an Object or notCreate a file "isObject.html" in your Angular project directory and copy-paste the following code snippet. angular.isObject() ...

The isString() method in AngularJS basically checks if a reference is a string value or not. This method will return True if the reference passed inside the function is a string, else it will return False.Syntaxangular.isString(value)Example − Check if the reference is a String or notCreate a file "isString.html" in your Angular project directory and copy-paste the following code snippet. angular.isString() Welcome to Tutorials Point ...
Read MoreAngularJS – ng-change Directive
The ng-change directive in AngularJS evaluates a given expression whenever the user changes the input. On every change, the ngChange directive is fired and the expression is evaluated immediately. The JavaScript onChange event only triggers at the end of a change (when the user leaves the form element or presses the key).Note − This directive also requires ngModel to be present.Syntax..Content..Example − ngChange DirectiveCreate a file "ngChange.html" in your Angular project directory and copy-paste the following code snippet. ngChange Directive ...

Suppose we have two matrices mat1 and mat2. We shall have to add these two matrices and form the third matrix. We shall have to do this by overloading the addition operator.So, if the input is like589679834763then the output will be131113131312To solve this, we will follow these steps −Overload the addition operator, this will take another matrix mat as second argumentdefine one blank 2d array vvDefine one 2D array vv and load current matrix elements into itfor initialize i := 0, when i < size of vv, update (increase i by 1), do:for initialize j := 0, when j < ...
Read MoreC++ program to overload extraction operator
Suppose we have a Person class with two attributes first_name and the last_name. It also has two methods called get_first_name() and get_last_name() to retrieve or set first name and last name respectively. We shall have to overload the extraction operator (
Read MoreC++ program to find maximum of each k sized contiguous subarray
Suppose we have an array with n elements and a value k. We shall have to find maximum value for each of the contiguous subarray of size k.So, if the input is like arr = [3, 4, 6, 2, 8], k = 3, then the output will be The contiguous subarrays of size 3 are [3, 4, 6], [4, 6, 2], [6, 2, 8], so the maximum elements are 6, 6 and 8.To solve this, we will follow these steps −Define one deque Qi of size kfor initialize i := 0, when i < k, update (increase i by 1), ...
