关于限制指针的规则,我有点困惑.也许有人可以帮助我.

1. 定义嵌套的受限指针是否合法,如下所示:

   int* restrict a;
   int* restrict b;
   
   
   a = malloc(sizeof(int));
   
   
   // b = a; <-- assignment here is illegal, needs to happen in child block
   // *b = rand();
   
   
   while(1)
   {
       b = a;  // Is this legal?  Assuming 'b' is not modified outside the while() block
       *b = rand();
   }

2. 导出受限指针值是否合法,如下所示:

   int* restrict c;
   int* restrict d;
   
   
   c = malloc(sizeof(int*)*101);
   d = c;
   
   
   for(int i = 0; i < 100; i++)
   {
       *d = i;
       d++;
   }
   
   
   c …
