Can 2 pointers point to same address?
Pointers: Pointing to the Same Address There is no limit on the number of pointers that can hold (and therefore point to) the same address.
Does pointers have its own address?
Yes, a declared pointer has its own location in memory. It is the compiler’s job to know where to “get the pointer.” When your source code refers to the pointer ‘a’, the compiler translates it into -> “whatever address value is stored in memory location 874”.
How do you make a pointer point to the same address as another pointer?
Pointer assignment between two pointers makes them point to the same pointee. So the assignment y = x; makes y point to the same pointee as x . Pointer assignment does not touch the pointees. It just changes one pointer to have the same reference as another pointer.
Is pointer the same as address?
A pointer is a variable that stores a memory address. Pointers are used to store the addresses of other variables or memory items. Pointers are very useful for another type of parameter passing, usually referred to as Pass By Address. Pointers are essential for dynamic memory allocation.
Are the expression * ptr ++ and ++ * ptr are same?
3) Are the expression ++*ptr and *ptr++ are same? The correct option is (b). Explanation: ++*ptr increments the value pointed by ptr and*ptr++ increments the pointer not the value.
Can pointers have the same name?
the question: can the code have a variable and a pointer with the same name? If they were each local to different functions (or different files) then they are in different ‘scopes’ then, YES then can have the same name. What you have is a variable names pointer whose type is int * , i.e. a pointer to an int .
Are the expression pointer plus plus and plus plus pointer are same?
Both operators have the same precedence, and right-left associativity. This means the expression will be grouped ++(*ptr) . The ++ part will be applied to the value of the *ptr part.
