SUMMARY

Accessing private variables of a class from another class can be achieved using the concept of friend classes in C++. In the provided example, class One contains a private array, and class Two needs access to this array within its printNumbers method. By declaring class Two as a friend of class One, it can directly access the private members of One. This approach is essential for encapsulation while allowing controlled access to private data.

PREREQUISITES
  • Understanding of C++ class structures
  • Knowledge of access specifiers (public, private, protected) in C++
  • Familiarity with the concept of friend classes in C++
  • Basic understanding of encapsulation in object-oriented programming
NEXT STEPS
  • Research the implementation of friend classes in C++
  • Learn about access control mechanisms in C++
  • Explore best practices for encapsulation in object-oriented design
  • Study the implications of using friend classes on software maintainability
USEFUL FOR

C++ developers, software engineers, and students learning object-oriented programming who need to understand class access control and encapsulation techniques.

how can i access the private variables of a class from another class?

for example...
Code:
class One{
  public:
     One();
  private:
     int array[6][7]    
};

class Two{
  public:
     Two();
  private:
     void printNumbers();
};

void Two::printNumbers(){
     // i want to access the array in class One here
}
