In this example, we will declare an integer variable and an integer pointer that will store the address of the integer variable. #include<iostream>usingnamespacestd;intmain(){inta;//normal integer variableint*ptr;//integer pointer declaration//pointer initializationptr=&a;//printing the address ...

We already know that a pointer holds the address of another variable of same type. When a pointer holds the address of another pointer then such type of pointer is known aspointer-to-pointerordouble pointer. In this guide, we will learn what is a double pointer, how to declare them and ...

Smart pointers automatically handle many of these problems. They are basically an object which behave like pointers i.e. wrap a bare pointer but provides extra functionality. So we should use these in place of bare pointers. Now, let us understand the basics of how smart pointers work. Please...
A service may be written to run as either a stand-alone process or as a part of the Service Controller's process (which creates a thread per service, and the service is allowed to create more threads). If the service runs in SC, the SC creates the thread for a service then loads it...
In the following example we regard the task to perform one of the four basic arithmetic operations. The taskisfirst solvedusingaswitch-statement. Then itisshown, how the same can be doneusinga function pointer. It's only an example and the task is so easy that I suppose nobody will ...
