how to go from ASCII to Byte?
I've got the following code:
| Code: |
char buf[256];
for(;;)
{
rc = recv(DestSocket,buf,sizeof(buf), 0);
printf("Received from Client: %s\n",buf);
}
return 0; |
Now i get the input like on the picture.
but I wanna convert it to bytes.
Like this
Received from Client hi => buf[] = {0x48, 0x61};
So it's easier for me to see what packets have been sent.

not sure which way you wanted to go but it is equally easy to typecast the other way
| Code: | #include "stdafx.h"
#include "windows.h"
#include <conio.h>
#include <iostream>
using namespace std;
int _tmain(int argc, _TCHAR* argv[])
{
int buf[] = {0x48, 0x61};
for ( int i = 0; i < (sizeof (buf)/sizeof (int)); i++ )
cout << (char)buf[i];
while(!_kbhit())
Sleep(100);
return 0;
} |

how about..
| Code: | #include "stdafx.h"
#include "windows.h"
#include <conio.h>
#include <iostream>
using namespace std;
int _tmain(int argc, _TCHAR* argv[])
{
int buf[] = {0x48, 0x61};
char charbuf[] = { 'H', 'a' };
for ( int i = 0; i < (sizeof (buf)/sizeof (int)); i++ )
cout << (char)buf[i];
for ( int i = 0; i < sizeof charbuf; i++ )
cout << "\n0x" << hex << (int)charbuf[i];
while(!_kbhit())
Sleep(100);
return 0;
} |
is that what he wants to do ?

Thanks all, fixed it.
I didn't need the iostream so just used stdio.h.
