# C++ Pointers to Classes
[ C++ Classes & Objects](#)
A pointer to a C++ class is similar to a pointer to a structure. To access members of a pointer to a class, you use the member access operator **->**, just like with a pointer to a structure. Like all pointers, you must initialize the pointer before using it.
In C++, a pointer to a class points to an object of that class. Similar to ordinary pointers, a pointer to a class can be used to access the object's member variables and member functions.
**Declaring and Initializing a Pointer to a Class**
## Example
#include
class MyClass {
public:
int data;
void display(){
std::cout<<"Data: "<< data << std::endl;
}
};
int main(){
// Create a class object
MyClass obj;
obj.data=42;
// Declare and initialize a pointer to the class
MyClass *ptr =&obj;
// Access member variable via pointer
std::cout<<"Data via pointer: "<data <display();
return 0;
}
When the above code is compiled and executed, it produces the following result:
Data via pointer: 42Data: 42
**Dynamic Memory Allocation**
A pointer to a class can also be used to dynamically allocate memory and create an object of the class:
## Example
#include
class MyClass {
public:
int data;
void display(){
std::cout<<"Data: "<< data <data =42;
// Call member function via pointer
