Write a C++ program in which use of wild pointer are demonstrated.

Wild Pointer in C++ language

Wild pointer are pointers that have not been initialized and can make a program crash or behave oddly. This is due to the fact that in the C++ programming language, pointers that are not specifically initialized point to unpredictable address in memory.

Write a C++ program in  which use of wild pointer are demonstrated.

   

#include<iostream>

using namespace std;

int main()

{

int *ptr ;

cout<<"Address on ptr is : "<< ptr;

cout<<endl;

cout<<"Value of address that is on ptr is : "<< *ptr;

return 0;

}

Explanation

: Here ptr is a wild pointer because it has not been initialized. There is a difference between the NULL pointer and wild pointer. Null pointer points the base address of segment while wild pointer doesn't point any specific memory location.

The above program output is tested on www.jdoodle.com

Output:

Address on ptr is : 0x563a1ceceadc

Value of address that is on ptr is : -443987883
