Constructor Fibonacci series C++ Program

Let’s see the Fibonacci series C++ Program with Constructor.

#include<iostream>
using namespace std;
class T4Tutorials
{
	public:
		T4Tutorials(int num)
		{
			int a=0,b=1,t,j;
			cout<<"enter the number :";
			cin>>num;
			cout<<"the fibonacci series is :"<<a<<b;
			for(j=1;j<=num;j++)
			{
				t=a+b;
				cout<<t;
				a=b;
				b=t;
			}
			cout<<"\n";
		}
};
int main()
{
	T4Tutorials obj(5);
}

#include<iostream>

using namespace std;

class T4Tutorials

{

public:

T4Tutorials(int num)

{

int a=0,b=1,t,j;

cout<<"enter the number :";

cin>>num;

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

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

{

t=a+b;

cout<<t;

a=b;

b=t;

}

cout<<"\n";

}

};

int main()

{

T4Tutorials obj(5);

}

Output

enter the number : 4

the fibonacci series is : 011235
