please give me a source code in C for a program that reproduce its exe code?

Answer 1

Here goes. It requires one command-line argument, which is the name to which the exe code is copied. Compiled and works under Borland C 4.5

#include
#include
#include
#include
#include
#define BACKSLASH '\\'

int main (int argc, char *argv[])
{
int i;
char *ptr;
char newname[256];
FILE *executable;
FILE *copy;
struct stat statbuf;
char *contentbuffer;
long count;

strcpy (newname, argv[0]);
ptr = newname;
while (*ptr) ptr++;
ptr--;
while ((*ptr != BACKSLASH) && (ptr > newname)) ptr--;
if (*ptr == BACKSLASH)
{
ptr++;
*ptr = 0;
strcat (newname, argv[1]);
strcat (newname, ".exe");
}


if ((executable = fopen(argv[0], "rb")) == NULL)
{
fprintf(stderr, "Cannot open executable file.\n");
return 1;
}

if ((copy = fopen(newname, "wb")) == NULL)
{
fprintf(stderr, "Cannot open copy of executable.\n");
return 2;
}

stat(argv[0], &statbuf);
contentbuffer = farmalloc (statbuf.st_size + 32);
if (contentbuffer == NULL)
{
fprintf(stderr, "Malloc error.\n");
return 3;
}

count = fread(contentbuffer, 1, statbuf.st_size, executable);
if (count != statbuf.st_size)
{
fprintf(stderr, "File read error. count = %d and buffer = %d\n", count, statbuf.st_size);
return 4;
}
count = fwrite(contentbuffer, 1, statbuf.st_size, copy);
if (count != statbuf.st_size)
{
fprintf(stderr, "File write error. count = %d and buffer = %d\n", count, statbuf.st_size);
return 5;
}
return 0;
}

Answer 2

Searhc for Reverse Compilers.

Answer 3

A decompiler? There were such a thing for unscrambled Java but I only heard of disassembler for Assemblies not working decompilers for others.

Such a thing would cause the digital equivalent of Hiroshima.

Answer 4

A COMPILER! LOL

Seriously though, you dont want to do this!

It will eventually put programmers out of work if computers can write their own code!

Answer 5

It is not that easy. May be you can contact a C expert at websites like http://homeworkhelp.co.in/

Answer 6

I do not see what you are trying to achieve, there is no possible useful purpose to this.
