int p, *pi; // This statement instructs the compiler to reserve a space for the variable p in memory to hold an integer value. pi=&a; // Assigns the address of the integer variable p to the pointer variable. For instance, if the address of p is 4581, then the value in the *pi...
A shared_ptr is used to represent shared ownership. It is a type of smart pointer that is designed for scenarios in which the lifetime of the object in memory is managed by more than one owner. Like theunique_ptr, shared_ptr is also defined in the <memory> header in the C++ Standard...

⟹ Key observation:We can play with the 16-byte bin that is used to serviceRequestobjects from the heap. If we could somehow get a dangling pointer to a Request object, we could corrupt that Request and then carefully use the corrupted object's overwrittenchar *strpointer to perform arbitr...
In the above example, I was trying to make the add10() function increment number 10, but it doesn’t seem to be working. It just returns 0. This is exactly the issue pointers solve. Using pointers in Go If we want to make the first code snippet work, we can make use of pointers...
