[縹緲]

如題,我在書上找到一個程式用來找並列埠位址

#include <stdio.h>
#include <dos.h>

void main(void)
{
unsigned int far *ptraddr;
unsigned int address;
int a;

ptraddr=(unsigned int far *)0x00000408;

for (a = 0; a < 3; a++)
{
address = *ptraddr;
if (address == 0)
printf("No port found for LPT%d \n",a+1);
else
printf("Address assigned to LPT%d is %Xh\n",a+1,address);
*ptraddr++;
}
}

但一直錯,而我這初學者又不知怎麼辦,請各位高手救命,謝謝~~~
