Your son can act as a pointer variable of sorts. The content of a can be obtained using pa.This is called dereferencing a pointer. Yes, but it needs to have the right type. D. Question 4. A pointer variable can be? True. False. Dereferencing a pointer can … B. change within a function. Join The Discussion. A pointer is also called reference type variable in generic way.int *pa = &a; can be stated like pa is a pointer to an integer.pa points to a.Just like a has a content (55), pa has a content (that's the address of a).As pa itself is a variable, it has an address too.. D. all. 2 Bytes. A C# pointer is nothing but a variable that holds the memory address of another type. If the pointer was set in a fixed block, the variable to which it points may no longer be fixed. The body of your question asks whether "a pointer is a data type or not". Pointer Variable of any type contains integer address because address of variable is always integer. In C++11, the nullptr keyword was introduced to represent the address 0. We need to store address of integer variable to integer pointer. This is somewhat analogous to a hotel. With pointer variables you can access but not modify data in other variables. Consider a method that returns a pointer to a local variable through an in, out, or ref parameter or as the function result. Home / Green Board / Miscellaneous / Question. What will be the size of integer pointer ? Answer: Option B . A. passed to a function as argument. You might tell your son that you will be in room 0x100 on your trip. But in C# pointer can only be declared to hold the memory address of value types and arrays. Oftentimes, these tricks are the only ways to … Passing pointers between methods can cause undefined behavior. C. return by a function. If you declare int *ptr, **ptr1;, then ptr1 has type "pointer to int *" and thus can point to ptr. 10 Bytes. A pointer is generally initialized as: datatype *variable name; This above declaration is a single pointer but there can be more … pointer-variable-name is a valid C identifier i.e. You can use reference operator & to get memory location of a variable or you can … There are two ways to initialize a pointer variable. How to initialize pointer variable. In your example int *ptr,*ptr1; both ptr and ptr1 have type "pointer to int", which can only point to an int, not a pointer. A pointer variable can be .

Consider the 32 bit compiler. As such, it can easily be flung off to a function in C programming. For example, given: int *ptr; ptr is a pointer object, and its type is int*, which is a pointer type. Pointers Pointer is a variable in C++ that holds the address of another variable.Like any variable or constant, you must declare a pointer before you can work with it. A. The general form of a pointer variable declaration is − type *var-name; Here, type is the pointer's base type; it must be a valid C data type and var-name is the name of the pointer variable. By any reasonable definition of the phrase "data type", pointer types are data types. the name of pointer variable. They have data type just like variables, for example an integer type pointer can hold the address of an integer variable and an character type pointer can hold the address of char variable.
