C 指针*p++与*++p
关于++i与i++,我们这里纠结了不止一次,到了指针,还得接着纠结:
#include <stdio.h>
int data[2] = {100, 200};
int moredata[2] = {300, 400};
int main(void)
{
int * p1, * p2, * p3;
p1 = p2 = data;
p3 = moredata;
printf(" *p1 = %d, *p2 = %d, *p3 = %d\n", *p1, *p2, *p3);
printf(" *p1++ = %d, *++p2 = %d, (*p3)++ = %d\n", *p1++, *++p2, (*p3)++);
printf(" *p1 = %d, *p2 = %d, *p3 = %d\n", *p1, *p2, *p3);
return 0;
}
