A void pointer, also known as a generic pointer, is a pointer that is not associated with any specific data type, making it suitable for pointing to any type of data. In other words, avoid pointercan point to an integer, a character, a string, or any other data type. This flexibility...
A pointer is a variable that is utilized for storing an object’s memory address. In C++, pointers are also used for iterating over an array’s elements or other data structures and many more purposes. Pointer variables are also created for user-defined types like structures. Let’s have ...
char *str = NULL; // Implicit conversion from void * to char * int i = NULL; // OK, but `i` is not pointer type 2️⃣ Function calling ambiguity void func(int) {} void func(int*){} void func(bool){} func(NULL); // Which one to call? Compilation produces the following ...
class node { private: int data; node* next; //pointer to object of same type public: //Member functions. }; ExplanationIn this declaration, the statement node *next; represents the self-reverential class declaration, node is the name of same class and next the pointer to class (object ...

Arrays:- When there is a need to use many variables then There is a big problem because we will Conflict with name of variables So that in this Situation where we wants to Operate on many numbers then we can use array . The Number of Variables also incre
The main() function uses a pointer of type Shape to point to objects of both the Circle and Rectangle classes, which represents dynamic binding. The appropriate draw() method is called based on the actual object being pointed to. This program will give the following output: Drawing a circle...
In C++, implement a recursive example in an OOP environment. 1) When passing an array to a function is it "by address" or "by value". Explain what happens and what is meant by the two terms. Write a function called my_str_n_cpy() that accepts pointer to a destinat...
