1Pointer arithmetic There are four arithmetic operators that can be used in pointers: ++, --, +, - 2Array of pointers You can define arrays to hold a number of pointers. 3Pointer to pointer C allows you to have pointer on a pointer and so on. ...
7. 误解指针运算(Misunderstanding Pointer Arithmetic) 在C/C++中,指针的算术操作是以它们指向的对象的大小为单位来进行的。例如下面函数的功能是扫描一个int的数组,并返回一个指针,指向val的首次出现: 1int*search(int*p,intval)2{3while(*p && *p !=val)4p +=sizeof(int);//Should be p++5returnp;6}...
http://stackoverflow.com/questions/3523145/pointer-arithmetic-for-void-pointer-in-c When a pointer to a particular type (say int, char, float, ..) is incremented, its value is increased by the size of that data type. If a void pointer which points to data of size x is incremented, ...
The correspondence between indexing and pointer arithmetic is very close. By definition, the value of a variable or expression of type array is the address of element zero of the array. Thus after the assignment pa = &a[0]; pa and a have identical values. Since the name of an array is...

如果,将括号加于方括号前,char (* argv)[]这样就是数组指针,Pointer of Array。 所以,不考虑初始化的前提下,argv 其实就是一个双重指针,但是,又不能将它等价看作char **,这解析为一个指向字符指针的指针,它们两者的区别主要体现在以下代码片断的初始化的过程中。char *argv[]需要一个地址列表来初始化,而cha...
