(*p)++和*（p++）和*p++的区别

Posted 2020-08-07

 * 和++优先级是同一级别，同一级别按照从右往左的顺序计算

所以:  *p++等价于*(p++) 

char *a="this a book";

   char *p = a;

   p++;

   printf("%c\n", *p);//output:h

   *p++;

   printf("%c\n", *p);//output:i

   /* overflow

   char x = (*p)++;

   printf("%d\n", x);

   */

   while (*p != ‘\0‘) {

       printf("%c", *p++);//is

   }

   printf("\n");
