When To Use Pointer To Pointer C++ at William Seymour-symers blog

When To Use Pointer To Pointer C++. When * is used with pointers, it's called the dereference operator. Use pass by value if the type fits into 4 bytes and don't want to have it changed after the return of. Assigning the address of a variable to a pointer using the unary operator (&) which returns the address of that variable. The first pointer is used to store the address of the variable. A pointer to a pointer is a form of multiple indirection or a chain of pointers. It is a variable that points to a data type (like int or string) of the same type and is. The pointer to a pointer in c is used when we want to store the address of another pointer. Normally, a pointer contains the address of a variable. In c++ a pointer is a variable that is used to store the memory address of other variables. It operates on a pointer and gives the value pointed by the address stored in the pointer. C++ allows the use of pointers that point to pointers, that these, in its turn, point to data (or even to other pointers). How to use a pointer? The syntax simply requires an asterisk ( * ) for each level of indirection in. That is, *point_var = var.
