To install PHP, we will suggest you to install AMP (Apache, MySQL, PHP) software stack. It is available for all operating systems. There are many AMP options available in the market that are given below:

• WAMP for Windows
• LAMP for Linux
• MAMP for Mac
• SAMP for Solaris
• FAMP for FreeBSD
• XAMPP (Cross, Apache, MySQL, PHP, Perl) for Cross Platform: It includes some other components too such as FileZilla, OpenSSL, Webalizer, Mercury Mail, etc.

If you are on Windows and don’t want Perl and other features of XAMPP, you should go for WAMP. In a similar way, you may use LAMP for Linux and MAMP for Macintosh.

Skills allow you to achieve your desired goals within the available time and resources. As a hacker, you will need to develop skills that will help you get the job done. These skills include learning how to program, use the internet, good at solving problems, and taking advantage of existing security tools.

In this article, we will introduce you to the common programming languages and skills that you must know as a hacker.

What is a programming language?

A programming language is a language that is used to develop computer programs. The programs developed can range from operating systems; data based applications through to networking solutions.  

Why should you learn how to program?

• Hackers are the problem solver and tool builders, learning how to program will help you implement solutions to problems. It also differentiates you from script kiddies.
• Writing programs as a hacker will help you to automate many tasks which would usually take lots of time to complete.
• Writing programs can also help you identify and exploit programming errors in applications that you will be targeting.
• You don’t have to reinvent the wheel all the time, and there are a number of open source programs that are readily usable. You can customize the already existing applications and add your methods to suit your needs.

What languages should I learn?

The answer to this question depends on your target computer systems and platforms. Some programming languages are used to develop for only specific platforms. As an example, Visual Basic Classic (3, 4, 5, and 6.0) is used to write applications that run on Windows operating system. It would, therefore, be illogical for you to learn how to program in Visual Basic 6.0 when your target is hacking Linux based systems.

Programming languages that are useful to hackers

SR NO.	COMPUTER LANGUAGES	DESCRIPTION	PLATFORM	PURPOSE
1	HTML	Language used to write web pages.	*Cross platform	Web hacking Login forms and other data entry methods on the web use HTML forms to get data. Been able to write and interpret HTML, makes it easy for you to identify and exploit weaknesses in the code.
2	JavaScript	Client side scripting language	*Cross platform	Web Hacking JavaScript code is executed on the client browse. You can use it to read saved cookies and perform cross site scripting etc.
3	PHP	Server side scripting language	*Cross platform	Web Hacking PHP is one of the most used web programming languages. It is used to process HTML forms and performs other custom tasks. You could write a custom application in PHP that modifies settings on a web server and makes the server vulnerable to attacks.
4	SQL	Language used to communicate with database	*Cross platform	Web Hacking Using SQL injection, to by-pass web application login algorithms that are weak, delete data from the database, etc.
5	Python Ruby Bash Perl	High level programming languages	*Cross platform	Building tools & scripts They come in handy when you need to develop automation tools and scripts. The knowledge gained can also be used in understand and customization the already available tools.
6	C & C++	High level programming	*Cross platform	Writing exploits, shell codes, etc. They come in handy when you need to write your own shell codes, exploits, root kits or understanding and expanding on existing ones.
7	Java CSharp Visual Basic VBScript	Other languages	Java & CSharp are *cross platform. Visual Basic is specific to Windows	Other uses The usefulness of these languages depends on your scenario.

* Cross platform means programs developed using the particular language can be deployed on different operating systems such as Windows, Linux based, MAC etc.

Other skills

In addition to programming skills, a good hacker should also have the following skills:

• Know how to use the internet and search engines effectively to gather information.
• Get a Linux-based operating system and the know the basics commands that every Linux user should know.
• Practice makes perfect, a good hacker should be hard working and positively contribute to the hacker community. He/she can contribute by developing open source programs, answering questions in hacking forums, etc.

C Standard library function

In this tutorial, you’ll learn about the standard library functions in C. More specifically, what are they, different library functions in C and how to use them in your program.

C Standard library functions or simply C Library functions are inbuilt functions in C programming.

The prototype and data definitions of these functions are present in their respective header files. To use these functions we need to include the header file in our program. For example,

If you want to use the printf() function, the header file <stdio.h> should be included.

#include <stdio.h>
int main()
{
   printf("Catch me if you can."); 
}

If you try to use printf() without including the stdio.h header file, you will get an error.

Advantages of Using C library functions

1. They work

One of the most important reasons you should use library functions is simply because they work. These functions have gone through multiple rigorous testing and are easy to use.

2. The functions are optimized for performance

Since, the functions are “standard library” functions, a dedicated group of developers constantly make them better. In the process, they are able to create the most efficient code optimized for maximum performance.

3. It saves considerable development time

Since the general functions like printing to a screen, calculating the square root, and many more are already written. You shouldn’t worry about creating them once again.

4. The functions are portable

With ever-changing real-world needs, your application is expected to work every time, everywhere. And, these library functions help you in that they do the same thing on every computer.

---

Example: Square root using sqrt() function

Suppose, you want to find the square root of a number.

To can compute the square root of a number, you can use the sqrt() library function. The function is defined in the math.h header file.

#include <stdio.h>
#include <math.h>
int main()
{
   float num, root;
   printf("Enter a number: ");
   scanf("%f", &num);

   // Computes the square root of num and stores in root.
   root = sqrt(num);

   printf("Square root of %.2f = %.2f", num, root);
   return 0;
}

When you run the program, the output will be:

Enter a number: 12
Square root of 12.00 = 3.46

Library Functions in Different Header Files

C Header Files
<assert.h>	Program assertion functions
<ctype.h>	Character type functions
<locale.h>	Localization functions
<math.h>	Mathematics functions
<setjmp.h>	Jump functions
<signal.h>	Signal handling functions
<stdarg.h>	Variable arguments handling functions
<stdio.h>	Standard Input/Output functions
<stdlib.h>	Standard Utility functions
<string.h>	String handling functions
<time.h>	Date time functions
