指针运算 meaning in Chinese

pointer operations

To maintain type safety and security , by default c does not support pointer arithmetic
为了保持类型安全，默认情况下， c #不支持指针运算。
Pyrex itself gives you access to all the c - level constructs that are most important for speed , while saving you from all the c gotchas of memory allocation and deallocation , pointer arithmetic , prototypes , and so on
Pyrex本身可以让您访问那些对速度至关重要的c级代码，而节省了编写内存分配、回收、指针运算、函数原型等的工作。
