常量指针(pointer to constant)和指针常量(constant pointer) 一个指针可以操作两个实体,一个是指针值(即地址),一个是间访值(即指向的实体)。于是指针的常量性也分为两种:常量指针(pointer to constant)和指针常量(constant pointer)。 指针常量是相对于指针变量而言的,也就是指针值不能修改的指针。常量指针是指向...
Constant Pointer to a Constant If you have understood the above two types then this one is very easy to understand as its a mixture of the above two types of pointers. A constant pointer to constant is a pointer that can neither change the address its pointing to and nor it can change ...

Pointer to constant assigned address that does not contain a value expand all in page Description This defect occurs when a pointer to a constant (const int*, const char*, etc.) is assigned an address that does not yet contain a value. For instance: int x; const int * ptr = &x; Ri...
A pointer to a constant is declared as :const int *ptr(the location of 'const' makes the pointer 'ptr' as a pointer to constant. Is an array a const pointer? yes, the array name isa constant pointer tothe first element of the array, and a constant cannot be change. An array name...

Pointers can be declared constant, which prevents the target of the pointer being written to. For example: Type pVoltage : POINTER TO CONSTANT INT; End_Type The compiler will report an error if you try and write a value via a constant pointer. For example: ...
