ng-repeat of Angular JS

 ng-repeat of Angular JS:-

It is used to display Array or JSON data similar to foreach loop of  Java.

We will mostly bind tables, drop-down lists, and Listbox data using ng-repeat.


Syntax of  ng-repeat

<tr ng-repeat="var in source"> <td>var</td> </tr>



Example of ng-repeat to bind data in the dropdown list :-


<!DOCTYPE html>
<html>
<head>
    <title></title>
    <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.9/angular.min.js"> </script>
</head>
<body>
<div ng-app="myApp" ng-controller="myCtrl">

<select ng-model="a">
   
<option ng-repeat="item in arr" value="{{item}}">{{item}}</option>

</select>

{{a}}
</div>

<script>
angular.module('myApp',[]).controller('myCtrl',function($scope){

    $scope.arr = ["C","CPP","DS","JAVA",".NET","PHP"];

})


</script>  

</body>
</html>

Q Another Example of ng-repeat of angular  JS using JSON?

JSON means Javascript Object notation, it is used to display data using key=>value pair.

JSON Use [] and  { }  to store element.

[]   --->  it contain multiple element

{} ----> Object



Single row  --->   {'rno':1001,'sname':'xyz'}

Multiple row----->    [ {'rno':1002,'sname':'xyz'}, {'rno':1001,'sname':'xyz'}, {'rno':1001,'sname':'xyz'}, {'rno':1001,'sname':'xyz'}]


<!DOCTYPE html>
<html>
<head>
    <title></title>
    <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.9/angular.min.js"> </script>
</head>
<body>
<div ng-app="myApp" ng-controller="myCtrl">

<table border="1">
   
<tr ng-repeat="item in arr"><td>{{item.rno}}</td><td>{{item.sname}}</td></tr>

</table>


</div>

<script>
angular.module('myApp',[]).controller('myCtrl',function($scope){

    $scope.arr =   [ {'rno':1002,'sname':'xyz'}, {'rno':1001,'sname':'xyz'}, {'rno':1003,'sname':'mno'}, {'rno':1004,'sname':'klmn'}];

})


</script>   

</body>
</html>

DSA in C# | Data Structure and Algorithm using C#

  DSA in C# |  Data Structure and Algorithm using C#: Lecture 1: Introduction to Data Structures and Algorithms (1 Hour) 1.1 What are Data Structures? Data Structures are ways to store and organize data so it can be used efficiently. Think of data structures as containers that hold data in a specific format. Types of Data Structures: Primitive Data Structures : These are basic structures built into the language. Example: int , float , char , bool in C#. Example : csharp int age = 25;  // 'age' stores an integer value. bool isStudent = true;  // 'isStudent' stores a boolean value. Non-Primitive Data Structures : These are more complex and are built using primitive types. They are divided into: Linear : Arrays, Lists, Queues, Stacks (data is arranged in a sequence). Non-Linear : Trees, Graphs (data is connected in more complex ways). Example : // Array is a simple linear data structure int[] number...
