Thread: MY DECRYTER IS COMPLETED! cept 4 spaces...

If you want to have some fun crypting messages to ur friends to decrypt, use it :P if you want to crypt programs and actual files... gimme some time!! IF YOU KNOW HOW TO SKIP SPACES AND NEWLINES PLEASE PLEASE PLEASE TELL ME! THEN I WILL BE DONE!! please try it and tell me how it works(remember, no spaces or newlines)

file...

Awwww, I'm so proud.

One thing, though.. You shouldn't define functions in header files. You put prototypes in header files and the function definitions in a .c file.

that header file to me, isnt really a header file... kinda. those arent normal functions... kind. heh. Im using it as my own personal library for every c++ file i make. So itll be easier to make them. did you see my cpp file? lol its not even a page, thanks to my library.

That's not the point.

This is how it should be:

main.cpp

Code:

#include "abbrev.h"

int main()
{
    // foo
}

abbrev.h

Code:

#ifndef ABBREV_H
#define ABBREV_H

#define MAX 1024

/* Function prototypes */
int foobar(int a);
char fooey(char *str);
void fubar(double stuf_oreo);

#endif

abbrev.c

Code:

#include's

int foobar(int a)
{
   printf("%c", a);
   return 0;

}

char fooey(char *str)
{
   printf("%s", str);
   return *str;
}

//etc. etc. etc.

Then you compile both abbrev.c and main.c together.

hehe, try:
#include <io.h>
#include <fcntl.h>
#include <iostream.h>

void main()
{
int i, j = 0;
int key_length;
int fh_in, fh_out;
long buffer_length;
long bytes_read = 0, file_length;
char in_buf[65536], out_buf[65536];
char infile[256], outfile[256];
char key[64] = {0};

cout << "SRC: ";
cin.getline(infile, 256, '\n');
cout << "DST: ";
cin.getline(outfile, 256, '\n');
cout << "PSW: ";
cin.getline(key, 64, '\n');

fh_in = open(infile, O_BINARY | O_RDONLY);
fh_out = open(outfile, O_BINARY | O_WRONLY | O_CREAT);

file_length = filelength(fh_in);

for (i = 63; i > 0; i--) if (key[i] == 0) key_length = i;

while (!eof(fh_in))
{
buffer_length = file_length - bytes_read;
if (buffer_length > 65536) buffer_length = 65536;

read(fh_in, in_buf, buffer_length);

for (i = 0; i < buffer_length; i++)
{
out_buf[i] = in_buf[i] ^ key[j];
j++;
if (j == key_length) j = 0;
}

write(fh_out, out_buf, buffer_length);

bytes_read += buffer_length;
}

close(fh_in);
close(fh_out);
}

works on all files, very optimized

hi there!

ur problem is quite simple. anyway, try to look up standard C's "ctype.h". functions like isspace() etc... like that exists there.

sample:

fread(&chr, sizeof(char), 1, filename);
if(isspace(chr) || chr == '\n') {
...more code...
...more code...
...break out to skip...
}

that's all u can improve it.
