[algogeeks] Os/processor dependencies of object file(C compiled file)

2011-08-10 Thread mithun bs
Hi,

I know that the compiled code of a C file(after assembler converts assembly
code to opcode) cannot be run on a different OS or it cannot be run on a
different processor architecture.

So, I need to know what are the machine dependencies which are added in
object file.

One thing is the opcode will be different for each processor architecture.
But how is it dependent on Operating system?

Re: [algogeeks] Reverse Bits

2011-08-05 Thread mithun bs
Hi Rajeev,

I follow similar approach. The basic logic is swap bits of a pair, then swap
nibbles(2 bits) and then swap (4bits), 8bits  and go on.

So for ex. 0110 1101 1100 0101
In first step, I swap bits of each pair. So this becomes,

Input -  0110 1101 1100 0101
output- 1001 1110 1100 1010

In second step, I swap 2bits

Input - 1001 1110 1100 1010
output-0110 1011 0011 1010

I swap 4 bits now

Input - 0110 1011 0011 1010
output-1011 0110 1010 0011

Now I swap 8bits
Input - 1011 0110 1010 0011
output-1010 0011 1011 0110

So, now we have the bits in reverse order.

First step I do this way
x = ((x | 0x)  2) | (x2) | 0x;
Next step similarly
x = ((x | 0x)  4) | (x4) | 0x;

This is the logic.
Your code does the reverse way.

Regards,
Mithun

 Could anyone please explain the logic of this approach ? Thank You !!

 #define reverse(x) \
 (x=x16|(0xx)16, \
 x=(0xff00ff00x)8|(0x00ff00ffx)8, \
 x=(0xf0f0f0f0x)4|(0x0f0f0f0fx)4, \
 x=(0xx)2|(0xx)2, \
 x=(0xx)1|(0xx)1)

Re: [algogeeks] a C question

2011-08-05 Thread mithun bs
The culprit in this program is printing a float variable with %d specifier.

printf(%d\n, t);
Removing this line, the program behaves normally.

This line may crash your program. Also it may remove some bytes from your
stack.
I feel this is what happening.

Even I am not very convinced. Still trying to find out !!!
