Fibonacci Series or Sequence


Levels of difficulty: / perform operation:

The Fibonacci numbers or Fibonacci series or Fibonacci sequence has first two numbers equal to 1 and 0 and the further each number is consist of the addition of previous two numbers
1st number = 0
2nd number = 1
3rd number = 0+1= 1
4th number = 1+1= 2
5th number = 1+2= 3
And so on.
The Fibonacci Sequence can be written as 0,1,1,2,3,5,8,13……..

C++ Program

#include <iostream>
    using namespace std;
int main() {
	int range, first = 0, second = 1, fibonicci=0;
	cout <> range;
	cout << "Fibonicci Series upto " << range << " Terms "<< endl;
	for ( int c = 0 ; c < range ; c++ ) {
		if ( c <= 1 )
		             fibonicci = c; else {
			fibonicci = first + second;
			first = second;
			second = fibonicci;
		}
		cout << fibonicci <<" ";
	}
	return 0;
