Basic Computer Programming Languages Principles

Today, We want to share with you Basic Computer Programming Languages Principles.
In this post we will show you Programming principles, hear for The Principles Of Good Programming we will give you demo and example for implement.
In this post, we will learn about Basic Programming Principles Every Programmer Must Follow with an example.

Overview

Programming principles have helped me over the years in becoming a better programmer and developer, and I also believe, this article will help every developer become more efficient and able to produce code which is easier to maintain. By following these coding and programming principles, you can save development and maintenance time, and conquer lots of other congestion which may arise in later development phases.

What are Programming principles?

Programming is the complete process, which involves various stages such as coding, testing, debugging and maintaining a system.Programming principles assist you to write good quality of code and maintain a good coding practice.

Why should a developer follow it?

Actually, writing programs is mostly a matter of personal taste but there are certain rules or guidelines that should be followed within your style of code in order to make programs easy to maintain and understand by both, you and others(your team), and also principles guide the creation of Optimized, scalable, easy to maintain, and robust code.

What are the benefits if developer follows Programming principles?

Readability

All developers which are in a team of project able to understand the code.

Extensibility

In the Software world, changes are needed on time to time, If we have followed rule properly then it will become very easy to implement new changes in software.

Maintainability

It becomes easy to maintain by the development team and the production support team too because the application is loosely coupled.

Modularity

Make a whole program into small reusable pieces: functions, modules, libraries,union, structures.

Conclusion

  • You should write a program that is self-explanatory.
  • Use Comment wherever required, It makes documentation easy.
  • You should write a code which should be easy to maintain among your team.

Apart from this properly written program would also be easy to debug.
These principles will help you and others in the team to write or deliver good, clean, and high-quality code.

Summary

You can also read about AngularJS, ASP.NET, VueJs, PHP.

I hope you get an idea about Computer Programming Principles.

angular Recursive Templates Dynamic nested Tree

angular Recursive Templates Dynamic nested Tree

In this Post We Will Explain About is angular Recursive Templates Dynamic nested Tree With Example and Demo.Welcome on Pakainfo.com – Examples, The best For Learn web development Tutorials,Demo with Example! Hi Dear Friends here u can know to Building Nested Recursive Directives in Angular Example

In this post we will show you Best way to implement AngularJS recursive template rendering, hear for recursion – How can I make recursive templates in AngularJS with Download .we will give you demo,Source Code and examples for implement Step By Step Good Luck!.

Recursive nested ng-repeats

In this Example,First of all Add or Include External Libs Like as a(jQuery, css etc..), and then create a simple index.php or index.html page.After that crate a simple javascript file like as a index.js or main.js, It is also add your web-application First Header Part to some priority set.After that Include your relevant CSS Class.

External Include file

AngularJS is a simple JavaScript framework Include one type of the (library) based on a very user friedly popular software mvc based architecture menas called the MVC.

   

index.html

The Angular simple directives and the User’s view HTML DOM in a web-application page form the HTML view. In our example(Pakainfo.com), the simple HTML view comprises the HTML All the element, and then simple two angular directives Like as a namely angular ng-app as well as agular ng-controller

<div>
    
        {{ subcatst.title }}
        <ul>
            <li>

        </ul>
    
    <ul>
        <li></li>
    </ul>    
</div>

index.js

The simple angular controller works as a all the data of the mediator between HTML views and models.

var liveApp = angular.module('liveApp', []);

liveApp.controller('liveCtrl', function ($scope) {



$scope.schlList = [
  { 
    title: 'schools',
    schlList: [
      {
        title: 'students',
        schlList: [
          {
            title: 'hsc'
          },
          {
            title: 'ssc'            
          }
        ]
      },

      {
        title: 'peon'
      },

      {
        title: 'Staff',
        schlList: [
          {

           })  
      }  
      $scope.loadSubCategory = function(){  
           $http.post("load_subcategory.php", {'product_id':$scope.category})  
           .success(function(data){  
                $scope.subcategories = data;  
           });  
      }  
 });  
 </script>

Step 3: Create PHP API SERVER SIDE files

load_category.php

<?php  
	 $db_con = mysqli_connect("localhost", "root", "[email protected]", "myDBName");  
	 $results = [];  
	 $query = "SELECT * FROM categories ORDER BY name ASC";  
	 $result = mysqli_query($db_con, $query);  
	 while($row = mysqli_fetch_array($result))  
	 {  
	      $results[] = $row;  
	 }  
	 echo json_encode($results);  
?>  

load_subcategory.php

<?php  
	 $db_con = mysqli_connect("localhost", "root", "[email protected]", "myDBName");   
	 $results = [];  
	 $data = json_decode(file_get_contents("php://input"));  
	 $query = "SELECT * FROM subcategories WHERE product_id='".$data->product_id."' ORDER BY name ASC";  
	 $result = mysqli_query($db_con, $query);  
	 while($row = mysqli_fetch_array($result))  
	 {  
	      $results[] = $row;
	 }  
	 echo json_encode($results);  
?>
