Write a C++ program to display the diamond-like pattern using the Friend Function.
If we declare a function friend int T4Tutorials_Function(T4Tutorials t); as a friend in a class T4Tutorials then this function friend int T4Tutorials_Function(T4Tutorials t); can access the private and protected members of the classT4Tutorials. You must know that a global function can also be declared as a friend function of the class.
Syntax of friend function in C++
class class_name
{
…
friend return_type function_name(arguments);

}
