About Data Recovery and Data Wiping

i always wanted to write about data recovery and data wiping, so it is here:- 
Have you ever thought of the deleted data, and it's whereabouts actually when you permanently delete some file or data from your computer it is still present on the hard drive or fragments of it, it stays over there until new data overwrites the deleted data, 
So is this deleted recoverable?
Yes Of course, you can recover the data in many ways using many softwares like the one that is available for free cost is 
RECVUVA it is available on FileHippo (click the link to go over there). By the way it is free of cost.


according to 2012 reviews, they are as follows:-


1.) Digital Rescue Premium


2.) Advanced Disk Recovery


3.) Recover My Files


4.) Data Recovery Wizard


5.) Total Recall


6.) Handy Recovery


7.) Windows Data Recovery


8.) R-Studio


9.) Quick Recovery


10.) Stellar Phoenix


also you may wonder "when the deleted files are on my hard drive, there is no privacy for me any more, but the answer is No, you can wipe the deleted data from hard drive too, it's too easy with these softwares
My best suggestion is to use Ccleaner software from FileHippo (click the link to go over there), it is also free of cost.


if you install AVG PC TuneUp 2012, in tools it has disk wiper, which is also effective in erasing your drive's information.


so from all this one can understand deleting data or formatting drives is not just enough to get rid of our data from computers.

A c program for reversing the strings without using string functions

Many of my friends have asked me about a c program for reversing the words (strings) without any garbage values at the end of reversed words, so finally here it is:



#include<stdio.h>
#include<conio.h>
int main()
{
char a[100],b[100];
int count=0,i=0,c;
clrscr();
printf("enter a word : ");
gets(a);
for(i=0;a[i]!='\0';i++)
{
count++;
}
printf("\nthe number of letters in the entered letter is : %d\n",count);
c=count;
for(i=0;i<count;i++)
{
b[i]=a[c-i-1];
if(b[i]=='\0')
break;
}
for(i=0;i<count;i++)
{
printf("%c",b[i]);
if(b[i]=='\0')
{
break;
}
}
getch();
return 0;
}

thank you and feel free to comment and suggest.
