指针小问题
#include<stdio.h>typedef unsigned long ulong;
int main(void)
{
char * pc=NULL;
int * pi=NULL;
double * pd=NULL;
long double * pld=NULL;
printf("%5lu%5lu\n%5lu%5lu\n%5lu%5lu\n",
(ulong)(pc+1),(ulong)(pi+1),
(ulong)(pd+1),(ulong)(pld+ 1),
(ulong)(pc+3),(ulong)(pld+ 3));
return 0;
}
/*结果
1 4
8 12
3 36
*/
我想知道那个12和36怎么来的
