Hi,
Could someone please help me to solve unhandled exception error when using visual C++ 2008? the error is displayed as follow: Unhandled exception at 0x00411690 in time.exe: 0xC0000005: Access violation reading location 0x00000008
Actually when I used visual c++ 6 in the past, there weren't any error and the program was running fine. But now ehen I use visual 2008, I am getting this Unhandled exception error.
Here is the program:
#include <stdio.h>
#include <stdlib.h>
#include <time.h>

// #include <winsock.h>
#include <windows.h>
#include "stdint.h"
// typedef __int64 int64_t // Define it from MSVC's internal type
// typedef unsigned __int32 uint32_t
#else
#include <stdint.h> // Use the C99 official header
#include <sys/time.h>
#include <unistd.h>
