C++ Program with Friend function to display the pattern like pyramid
Write a C++ Program to display the pattern like pyramid using the alphabet using the friend function. The pattern is as follows :
If we declare a function friend int show(T4Tutorials p); as a friend in a class T4Tutorials then this function friend int show(T4Tutorials p); 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);

}
