I have made a formula/algorithm for compression and decompression. The plus point of this formula is that it does not require the 7 different cases for compression or decompression at different bits.

why?

project status MDC

rahul1989 — Sat, 11 Aug 2012 06:03:00 +0000

i have finished the compression and decompression.

i started development on this project

MULTIPE DATA COMPRESSION AND ENCRYPTION BY USING ITERATIVE TECHNIQUE PROJECT COMPLETED ON DEAD LINE 31 JULY

rahul1989 — Tue, 31 Jul 2012 02:57:47 +0000

I HAVE SUCCESSFULLY COMPLETED THE DATA COMPRESSION AND DECOMPRESSION. I HAVE TESTED THE PROGRAM FOR 1257 BYTES. IT IS WORKING WELL. THE CONCEPT THAT I HAD APPLIED IS WORKING VERY WELL.

object

rahul1989 — Fri, 20 Jul 2012 04:28:02 +0000

i need descriptive explanation.

warning on arrays

rahul1989 — Sun, 01 Jul 2012 04:25:59 +0000

{

char r[10]=”this is a”;
char d[10]={{‘t’},{‘h’},{‘i’},{‘s’},{‘ ‘},{‘i’},{‘s’},{‘ ‘},{‘a’}};

printf(“string r[10] %s size %d\n”,r,sizeof(r));
printf(“single character d[10] %s size %d\n”,d,sizeof(d));

return 0;

}
during compilation it gives warning WHY ?

what wrong i had done in char d[10] ?

warning: braces around scalar initializer [enabled by default]

warning: (near initialization for ‘d[0]’) [enabled by default]

why value are not reading trough scanf

rahul1989 — Fri, 29 Jun 2012 22:57:52 +0000

#include
int main()
{
double a,b,c;

printf(“Enter the temprature in fahrenheit “);
scanf(“%e”,&a);
c=1.8*a+32;
b=1.8*a+32+273.16;
printf(“the conversion in fahrenheite %e celcius is %3.2e and is %6.2\n”,a,c,b);

return 0;
}

i am reading the value through scanf and storing the value in double a as highlighted.

i am getting only garbage at output why.
Enter the temprature in fahrenheit 21 //what had happened to a ? why its is not storing the value.

the conversion in fahrenheite 1.978588e+65 celcius is 3.56e+65 and is 3.56e+65
