We can define pointer of class type, which can be used to point to class objects.class Simple { public: int a; }; int main() { Simple obj; Simple* ptr; // Pointer of class type ptr = &obj; cout << obj.a; cout << ptr->a; // Accessing member with pointer } ...
A pointer to function can be initialized with an address of a function. Because of thefunction-to-pointerconversion, the address-of operator is optional: voidf(int);void(*pf1)(int)=&f;void(*pf2)(int)=f;// same as &f Unlike functions, pointers to functions are objects and thus can ...
The programming community is in consensus that these objects are considered true pointers. The standard does not prescribe the nature of a pointer; however, C is, by design, close to the machine and efficient with computing time and memory, and, therefore, in essentially all implementations of...

Pointers to objects A pointer to object can be initialized with the result of theaddress-of operatorapplied to an expression of object type (which may be incomplete): intn;int*np=&n;// pointer to intint*const*npp=&np;// non-const pointer to const pointer to non-const intinta[2];int...
C_POINTER($MyPointer) $MyPointer:=->$MyVar The -> symbol means “get a pointer to.” This symbol is formed by a dash followed by a “greater than” sign. In this case, it gets the pointer that references or “points to” $MyVar. This pointer is assigned to MyPointer with the ass...
