The this pointer holds the address of current object, in simple words you can say that this pointer points to the current object of the class. Let's take an example to understand this concept. C++ Example: this pointer Here you can see that we have two d
shared pointer in C++ is a reference counted pointer. It follows concept of shared ownership after initializing a shared_ptr you can copy it.
I hope this post will be helpful to understand the concept of pointers in C++. Here, I just wrote simple examples of pointers in C++. If you want to practice more examples on pointers, visit: C pointers examples/programs.C++ - Size of structure with no members C++ - exit(0) vs exit...
Let us try the following example to understand the concept of this pointer − #include<iostream>usingnamespacestd;classBox{public:// Constructor definitionBox(doublel=2.0,doubleb=2.0,doubleh=2.0){cout<<"Constructor called."<<endl;length=l;breadth=b;height=h;}doubleVolume(){returnlength*bread...
Second, it can sometimes be useful to have a member function return the implicit object as a return value. The primary reason to do this is to allow member functions to be “chained” together, so several member functions can be called on the same object in a single expression! This is ...
Labs, the bug is CVE-2018-8120 that was fixed in the May patch. The vulnerability exists in the kernel functionSetImeInfoEx. In the case where the pointer fieldspklListof the target window station has not been validated, the function directly reads the memory address pointed to by the ...
(a) Describe the concept of a cursor. (b) How is it used in embedded SQL? Give an example of a program that uses the non-generic version of a class from the STL and the equivalent program that uses the generic version. How do the two implementations differ? Why is ...

Lets take an example, to understand the complete concept.class Data { public: int a; void print() { cout << "a is "<< a; } }; int main() { Data d, *dp; dp = &d; // pointer to object int Data::*ptr=&Data::a; // pointer to data member 'a' d.*ptr=10; d.print(...
Many changes may take place between that time and the current time and there is no guarantee that the Active Directory replication mechanism will be able to reconcile everything accurately because (unlike public folders) there is no concept of a backfill request to allow one replica of the ...
