But that is a mistake.

System( ) Function in stdlib.h Library

The C library function system() passes the command name or program name specified by a command to the host environment to be executed by the command processor. After the execution of the command it returns a value depending on the status of the execution. 

Declaration: 
To use this function,

 int system( const  char *command )    

         When you call this function, It  will invoke the command processor to execute a command. If the command execution is terminated the processor will trasnfer the control back to the program that has called the system command.

Parameters:
                 String containing name of system command or requested variable. 

Return Value:
            It will return an integer value, but the interpretation of that is system dependant. So, on different systems it gets interpreted differently. If an error occured in the program execution, '-1' is returned, Ootherwise it returns the status of command.

Click here to know how you can restart your computer using system function.

Random Numbers Generation

Random Number generation is very important aspect of many games, Cryptographic key generation and for other programs with a lot of outcomes. Let us take a look at how we generate those in C language and PHP. 
Before you proceed to the explanation, you need to know that a computer can never generate a Random number. It has to use some parameters to generate that number and so such numbers can never truly be Random. So, they are called Pseudo-Random Numbers and this tutorial deals with these. 

We have a built-in library function namely 'int rand(void )' in C. It gives the random number between 0 and RANDMAX. 
The value of RANDMAX is entirely library dependent, but it is guaranteed to be at least 32767 on any standard library implementation.

Then how to get numbers in the range we want ?

Let's say we want numbers only in between 100 and 1000. It is not directly possible with rand().

We have to use some of our math skills here with the use of  the operator , modulo (%).

I am very sure that you have used this operator before. It gives the remainder when one number is divided by another. (Check this tutorial if you are unsure)

The classy part of using this operator is that the remainder is always less than divider. So, the expression "X % 101" (X is some number) gives always a number less than 101 and greater than or equal to zero.

Let's come to our question , to generate numbers in between 100(101=min) and 1000(999=max) ,we need the expression

                                      result = rand( ) % 899 +101

where 899 is max-min+1 (999-101+1).

Why is porn so addictive ?

Why Is Pornography So Addictive ?

             
     Have you ever wondered why Pornography is so addictive and why many people get addicted to it! You will find out everything about this during the course of this article.
     25% of the total search requests to any search engine is porn, though some people believe that it is a lot higher than those numbers. It is also the 4th most common reason given by people for going to the internet. Some stats even show that pornography is affecting the life of every individual on the face of the planet either directly or indirectly.
         Pornography addiction is spreading like an epidemic these days. Never in the history of Internet was porn as crucial and active as is in these days and it has changed from a global phenomenon to a global problem very fast. Some stats are showing that Pornography constitutes to about
       
          Pornography is in many ways like a drug to the brain and with continuous exposure people find themselves addicted to it and their tolerance increases much like any other drug. Just like a drug it leads to the loss of control over oneself and compulsiveness to engage in the activity more despite of the negative consequences. Long term exposure may lead to permanent changes in the neural network. Dopamine (DA) is produced when ever we feel happy or accomplish something. This Dopamine sort of  re-wires your brain to perform the same action again and again thus leading to addiction. So, what is produced as a New-Normal becomes more and more evident and our brain/body craves for this Dopamine to regain that new Homeostasis (the new equilibrium). This Dopamine is produced during sexual excitement and now you know the reason for addiction. Along with Dopamine some other hormones like Serotonin, Norepinephrine

     The more of Pornography you watch the more Dopamine (DA) is released
 and the more you will be forced to watch again forming a 'Trap Cycle', coming out of which is very difficult. More over, the more you watch the more your tolerance increases and it becomes more difficult to get turned on by Reality. This may also lead to finding your mate less attractive.
                 
                 
                    Here Comes the GOOD NEWS. As our brain is a USE IT or LOSE IT system the addicted people still have a way out. The neural connections which you use tend to get Stronger and Stronger while those which you don't tend to get weakened and ultimately you tend to lose those qualities. So, Get more good habits and Avoid or Ignore the bad habits and you will come out of the Trap Cycle. Some experts view pornography as a dysfunctional view of society towards sexuality.
   
     Any way now you know that Pornography become a great problem to a person and it potentially capable of getting you in to troubles. So, beware and BE AWARE.  :)
