Full Discussion: C++ = new and delete

C++ = new and delete
This is one basic question regarding C++ new and delete operator.


# include <iostream>
int main()
{
int *ptr = new int(10);
int i=0;
for (i=0 ; i<10 ;i++)
ptr[i] = 10;

delete [] ptr;
printf("%d",ptr[5]); // It prints the value 10

}

In the above program memory for the *ptr is created using new operator and the same memory is deleted using the delete. But after deleting the ptr also I can able to access the memory location using the ptr .
So any one please explain me what new() and delete() actually does.
