Fibonacci series C++ Program with friend function

Fibonacci series C++ Program with friend function, classes, and objects in object-oriented programming.

#include<iostream>
using namespace std;
class T4Tutorials
{
private:
	int a=0;
	int b=1;
	int t,num;
	public:
		T4Tutorials()
		{
			cout<<"enter the number :"<<endl;
			cin>>num;
			cout<<"the fibonacci series is :"<<a<<b;
			for(int j=1;j<=num;j++)
			{
				t=a+b;
				cout<<t;
				a=b;
				b=t;
			}
		}
		friend int show(T4Tutorials);
	};
	int show(T4Tutorials num)
	{
		cout<<"\n";
	}
	int main()
	{
		T4Tutorials num;
		show(num);
	}

#include<iostream>

using namespace std;

class T4Tutorials

{

private:

int a=0;

int b=1;

int t,num;

public:

T4Tutorials()

{

cout<<"enter the number :"<<endl;

cin>>num;

cout<<"the fibonacci series is :"<<a<<b;

for(int j=1;j<=num;j++)

{

t=a+b;

cout<<t;

a=b;

b=t;

}

friend int show(T4Tutorials);

};

int show(T4Tutorials num)

{

cout<<"\n";

}

int main()

{

T4Tutorials num;

show(num);

}

Output

enter the number : 4

the fibonacci series is : 011235
