Introduction Bootstrap

Bootstrap is the world’s most popular framework for building a responsive website with a mobile view. Its provides all feature for the responsive web. When you using CSS it can be very easy to create an HTML Structure.

Let’s start first with how can use Bootstrap and the important requirements for use-

Below code called Bootstrap CDN name “bootstrap.min.css”. It is very important for create a Bootsrap can use cdn Online or Ofline below are line you can from Click Here . Here are very different version Minimum Version of V2.3.2 or latest version V5.0.

Tutorials for PHP Conditioning

What is PHP Conditioning?

PHP, like other programming languages, allows you to build code that executes multiple behaviors based on the results of logical or equivalent testing conditions. This presupposes that test conditions may be written in terms of expressions that evaluate true or false, and that actions can be carried out based on the results.

PHP allows programmers to assess numerous situations and determine whether they are true or false during the programming process.

A conditional statement is a programming structure that conveys these circumstances and their associated behavior.

What are the types of conditional statements?

If the test condition is not used, PHP is used. There are several ways to use a sentence in PHP.

  • The if statement
  • The if…else statement
  • The if…elseif….else statement
  • The switch…case statement

Getting input from users in JavaScript

prompt( ) – The browser provides a built-in function that can be used to get input
from the user, named prompt. The prompt( ) method displays a dialog box that prompts
the visitor for input.

Once the prompt function obtains input from the user, it returns that input.

Syntax: – prompt(text, defaultText)

Ex:- prompt(“Enter Your Name: “, “name”);
prompt(“Enter Your Roll No. : “);

JavaScript Operators

  • Arithmetic Operators
  • Comparison (Relational) Operators
  • Logical Operators
  • Bitwise Operators
  • Assignment Operators

Arithmetic Operators

Arithmetic operators perform addition, subtraction, multiplication, division, exponentiation, and modulus operations.

%Modulus operator to get
the remainder in integer division
++IncrementA = 10;
A+ +
DecrementA = 10;
A− −

Relational Operators

<Less than5<2False
>Greater than5>2True
<=Less than or equal to5<=2False
>=Greater than or equal to5>=2True
=Equal to5==2False
!=Not equal to5! =2True
===Equal value and same type5 === 5
5 === “5”
!==Not Equal Value or Not
same type
5 ! == 5
5 ! == “5”

Logical Operators

&&Logical and(5<2)&&(5>3)False
||Logical or(5<2)||(5>3)True
!Logical not!(5<2)True

Bitwise Operators

<<Shifts the bits to left
>>Shifts the bits to the right
~Bitwise inversion (one‟s complement)
&Bitwise logical AND
|Bitwise logical OR
^Bitwise exclusive or

Bitwise logical AND &

Operand 1Operand 2Result (operand1&operand2)

What is git?

Git is software for tracking changes in any set of files, usually used for coordinating work among programmers collaboratively developing source code during software development. Its goals include speed, data integrity, and support for distributed, non-linear workflows.

Why do we need git?

Git is the most commonly used version control system. Git tracks the changes you make to files, so you have a record of what has been done, and you can revert to specific versions should you ever need to. Git also makes collaboration easier, allowing changes by multiple people to all to be merged into one source.

What is the role of Git repository managment systems?

  • Git is a free and open source distributed version control system designed to handle everything from small to very large projects with speed and efficiency.
  • It outclasses SCM tools like Subversion, CVS, Perforce, and ClearCase with features like cheap local branching, convenient staging areas, and multiple workflows.
  • A Git repository is the . git/ folder inside a project.
  • This repository tracks all changes made to files in your project, building a history over time.
