What is the difference between friend function and inheritance in c plus plus?
There is no such thing. When declaring a friend function only the explicitly-scoped friend is granted private access. The friend function may well be declared virtual within its own class but none of its overrides are granted access unless they are explicitly granted access.
What is the latent function of friends?
The only function of a friend is to extend the private class interface outwith the class, essentially making the friend part of the class interface.
Why a friend function cannot be used to overload the assignment operator?
Assignment(=) operator is a special operator that will be provided by the constructor to the class when programmer has not provided(overloaded) as member of the class.(like copy constructor). When programmer is overloading = operator using friend function, two = operations will exists: 1) compiler is providing = operator 2) programmer is providing(overloading) = operator by friend function. Then simply ambiguity will be created and compiler will gives error. Its compilation error.
Write down a program with Passing object to friend function?
Here's a simple example of a C++ program that demonstrates passing an object to a friend function: #include <iostream> using namespace std; class Box { private: int length; public: Box(int len) : length(len) {} friend void printLength(Box b); // Friend function declaration }; void printLength(Box b) { // Friend function definition cout << "Length of box: " << b.length << endl; } int main() { Box box(10); printLength(box); // Passing object to friend function return 0; } In this program, the printLength function is declared as a friend of the Box class, allowing it to access the private member length.
Why we make a function friend in c plus plus?
A "normal" function is just a function. Even a friend function is just a normal function. However, when a class declares an external function or an external class method to be a friend of the class, the friend function gains access to the private members of the class. class foo { friend void bar(foo&); int m_data; }; void bar(foo& f) { f.m_data=42; } In the example above, the foo class declares the bar function to be a friend function. As such, the bar function has unrestricted access to the private members of foo. In this case, foo::m_data is private (by default) and would therefore be inaccessible to bar were it not declared a friend of foo. Other than that, the bar function is no different to any other function. Note that you cannot declare friendship from outside of a class. The class itself must declare its own friends. However, the same function can be declared friends in more than one class, which can be a useful feature when two or more classes work closely together, as the friend function can be used to provide the "glue" that binds them together.

What responsibility have to do with privileges?
Responsibilities and privileges are interconnected concepts; privileges often come with the expectation of responsibility.

Fulfilling these responsibilities can help maintain or enhance trust and respect within a community. Conversely, neglecting responsibilities can lead to the loss of privileges.

Access privileges granted to a user program or process is defined as?
Access privileges granted to a user program or process are defined as the permissions or rights assigned to that program or process to perform specific actions on system resources, such as files, directories, or devices. These privileges determine what operations the program can execute, such as reading, writing, or executing files, and help enforce security by limiting access to sensitive information and functionalities. Proper management of access privileges is essential for maintaining a secure computing environment.
